Pilot controlled servo valves, type ICS
Introduction
ICS servo valves belong to the ICV (Intelligent Control Valve) family and are one of two product groups.
The function of ICS valves is dependent on the pilot pressure applied from either a pilot valve or external pilot pressure source.
ICV types – ICS - Industrial Control Servo – ICM - Industrial Control Motor
ICS 1 pilot has one pilot pressure connection and ICS 3 pilot has three pilot pressure connections.
The valve comprises three main components: valve body, function module and top cover. ICS servo valves are pilot operated valves for regulating pressure, temperature, and ON/OFF function in refrigeration systems. ICS valves are designed for low and high-pressure refrigerants. ICS valves can be used on the high and lowpressure sides, in wet and dry suction lines and in liquid lines without phase change (i.e. where no expansion takes place in the valve).

Applicable to all common refrigerants including R717 and R744 (CO2) and non corrosive gases/liquids. Direct coupled connections to eliminate leak potential Low temperature steel body (-76 to 248oF) Low weight and compact design. V-port regulating cone ensures optimum regulating accuracy particularly at part load. Function module has a Teflon (PTFE) piston ring ensuring precise control accuracy. Modular Concept – Valve overhaul is performed by simply replacing the function module – Possible to convert ICS servo to ICM motor valve
RD4YA222 → DKRCI.PD.HS0.A1.22 / 520H0413
The associated Danfoss pilot valves can be either screwed directly into the ICS valve or connected via an external pilot line. Several pilot valves can be used on one ICS valve to provide numerous variations in control functions. The ICS valve top cover includes a pressure gauge connection port which can be used to monitor the valve inlet pressure when setting and adjusting the pilot valves. The spindle in the top cover can be used for manually opening the ICS valve.
Manual opening. Pressure gauge connection port to measure valve inlet pressure. The top cover can be rotated into any one of four positions without affecting the operation of the valve.

Pilot controlled servo valves, type ICS
Design
ICS valves are designed as pilot operated valves requiring minimal pressure differential to open. If the pressure difference is 0 psi/0 bar, the ICS valve will be closed. If the pressure difference is 3 psi / 0.2 bar or more, the ICS valve will be fully open. At pressure differences between 1 psi / 0.07 bar and 3 psi / 0.2 bar, the opening degree will be correspondingly proportional. The ICS is available for use with either one, two, or three pilot valves. Two of the three pilot pressure connections (S1 and S2) are connected in series while the third (P) is connected in parallel to S1 and S2. This allows different combinations of pilot valves to be used, thus providing numerous variations in control functions.
Approvals The ICV valve concept is designed to fulfil global refrigeration requirements. For specific approval information, please contact Danfoss. The ICS valves are approved in accordance with the European standard specified in the Pressure Equipment Directive and are CE marked.

The ICS main valve is a pilot operated valve. The types of pilot valves used determine the function. The ICS main valve with pilot valve(s) controls refrigerant flow by modulation or on/off in accordance with the pilot valve and main valve status. The manual spindle can be used to open the valve plate.
The maximum pressure (p2) can act on the top of the servo piston (3b). p2 normally corresponds to the pressure, p1 - ICS main valve inlet pressure. Inlet pressure p1 is led, via the drilled channels (1a, 1b, 2f, 2b (pilot), 2a, 2d) in the valve body (1) and cover (2) through the individual pilot valves and onto the top of the servo piston (3b).
The degree of opening of the main valve is determined by the pressure difference (differential pressure) between pressure p2, which acts on top of the servo piston (3b), and pressure p3, which acts on the underside of the servo piston.
The degree of opening of the individual pilot valves determines the magnitude of pressure p2 and thus the degree of opening of the main valve. The equalization hole (3f ) in the servo piston (3b) ensures that pressure p2 is balanced in accordance with the degree of opening of the pilot valve.
If this pressure difference is 0, the main valve will be fully closed. If the pressure difference is 3 psi (0.2 bar) or greater, the main valve will be fully open. At pressure differences (p2 - p3) between 1 psi (0.07 bar) and 3 psi (), the degree of opening will be correspondingly proportional. The port of the throttle cone (3e) is V-shaped, which provide good regulation characteristic to pilot operated main valves even at low loads. P3 pressure is equal to the valve outlet pressure (P4), due to a clearance between the spindle (3g) and the spring support plate (3h) in the function module. The opening degree of the ICS valve is therefore controlled by the application of P2 pressure acting on top of the servo piston, which is equal to or greater than valve outlet pressure (P4). p2 = p4 ~ closed p2 = p4 + 3 psi (0.2 bar)~ fully open p4 ≤ p2 ≤ p4 + 3 psi (0.2 bar) ~ proportional degree of opening.

Note: When ICS valves with 3 pilot ports are used with external pressure connector (fig. 2, pos. 61), the valve port inlet pressure will be isolated. Single Pilot Function The ICS can be fitted with just a single screwedin pilot valve or external pilot connection. The degree of opening of the main valve will be in accordance with the control status of the pilot valve or external pilot flow control. ICS main valve with one pilot connection is fully closed when the pilot valve is fully closed and fully open when the pilot valve is fully open. Otherwise the degree of opening of the main valve is proportional to the degree of opening of the pilot valve. Multiple Pilot Function The ICS 3 pilot version can be fitted with one, two, or three pilot valves so that up to three multiple functions are possible. If the external pilot connection is used, more functions can be added.

Technical leaflet Function (continued)
Pilot controlled servo valves, type ICS In the ICS three pilot version, the pilot ports are related as follows: The pilot valves fitted in ports SI and SII are connected in series. The ICS 3 pilot operated main valve will be fully closed if just one of the series-connected pilot valves is closed and the P port is plugged. The main valve can only open if both pilot valves are open at the same time. The pilot valve fitted in port P is connected in parallel to the pilot valves in ports SI and SII. The ICS valve will be fully open if the pilot valve in P is fully open, irrespective of the degree of opening of pilot valves SI and SII. The ICS valve will be fully closed if the pilot valve in P is fully closed and at least one of the valves in SI or SII is fully closed at the same time. The relation between the pilot valves in ports SI, SII and P is shown in Table 1. If the ICS is not fitted with three pilot valves, the unused port(s) must be sealed with a pilot cap A or a combination of pilot cap A and blanking plug B. If the pilot cap and blanking plug are fitted as an assembled unit, A + B, the channels from the specific port will be closed. (See Figure 1) If only cap A is fitted, the channels from the ports in question will be open. If the degree of opening of the ICS main valve is not to be a function of the main valve inlet pressure, or if more than three
regulating functions are required, ports SI, SII or P can be fitted with a nipple for the connection of external pilot pressure. This applies to all ICS versions. The pressure to which the external pilot line is connected will then determine the main valve function. Pilot valves installed in external lines must be mounted in a type CVH housing. Depending on the function of the pilot valves, the ICS regulating characteristic becomes: on/off proportional integral or cascade. ICS main valves are therefore especially suitable for all forms of temperature and pressure regulating systems. An overview of the types of pilot valves available can be found in Table 2, or technical leaflet: “Pilot valves for operated main valves” (RD4XC). On the following pages, a number of standard configuration examples can be found. These are only for explanatory purpose. However, by using the literature regarding pilot valves these examples are easier to comprehend.

Pilot controlled servo valves, type ICS
Steps for ordering valves assembled with pilots: Step 1: Specify ICS valve (ICS type, connection size/type), Tables 4-8, pages14-18. Step 2: Specify regulator configuration, consult Danfoss for variations not listed, Figures 3-14 Step 3: Specify coil voltage and accessories where applicable. Note: Review default pilot types/ranges and note any substitutions from Table 2, page 8. Example for ordering: Dual inlet pressure regulator type ICS with ¾” Port size, 1” SOC connections and gauge valve with adapter for fitting into regulator. Item 1: ICS 25-20-D with 1” SOC connections (see Figure 11) Item 2: ¼” gauge valve with adapter, p/n 148B418062 (selected from ICS accessories) Standard configurations Figure 3 - Solenoid Valve

Correction factor for ∆p 4 psi, f∆p = 0.87 Correction factor for liquid temperature f Tliq = 0.92
Running conditions in a plant are as follows: Te = –20°F Qo = 130 TR Liquid temperature = 50°F Max. ∆p = 4 psi
Qn = Qo × f∆p × f Tliq = 130 × 0.87 × 0.92 = 104 TR From the capacity table a ICS25-15 with Qn capacity 174 TR is selected.
The capacity table is based on nominal condition (pressure drop ∆p = 3 psi, Tliq = 90°F) Therefore the actual capacity must be corrected to nominal condition by means of correction factors.

Calculation example (R 717 capacities): Running conditions in a plant are as follows: Te = –20 F Qo = 130 TR Circulation rate = 3 Max. ∆p = 4 psi
Correction factor for ∆p 4 psi, f∆p = 0.87 Correction factor for circulation rate frec = 0.75 Qn = Qo × f∆p × frec = 130 × 0.87 × 0.75 = 85 TR From the capacity table a ICS 25 with Qn capacity 112 TR is selected.
The capacity table is based on nominal condition (pressure drop ∆p = 3 psi, circulation rate = 4) Therefore the actual capacity must be corrected to nominal condition by means of correction factors.

Nominal capacities Calculation example (R 717 capacities): An application has folowing running conditions: Te = –20 F Qo = 8 TR Circulation rate = 3 Max. ∆p = 4 psi
Correction factor for ∆p 4 psi, f∆p = 0.87 Correction factor for circulation rate frec = 0.9 Qn = Qo × f∆p × frec = 8 × 0.87 × 0.9 = 6.3 TR From the capacity table a ICS 25 with Qn capacity 9.8 TR is selected.
The capacity table is based on nominal condition (pressure drop ∆p = 3 psi, circulation rate = 4) Therefore the actual capacity must be corrected to nominal condition by means of correction factors.

Nominal capacities Calculation example (R 717 capacities): An application has folowing running conditions: Te = 0°F Qo = 20 TR Tliq = 50°F Max. ∆p = 4 psi
Correction factor for ∆p 4 psi, Tliq = 0.87 Correction factor for liquid temperature fTliq = 0.92 Qn = Qo × f∆p × f Tliq = 20 × 0.87 × 0.92 = 16 TR From the capacity table a ICS 25 with Qn capacity 23.4 TR is selected.
The capacity table is based on nominal condition (pressure drop ∆p = 3 psi, Tliq = 90°F) Therefore the actual capacity must be corrected to nominal condition by means of correction factors.

Discharge line Calculation example (R 717 capacities): An application has folowing running conditions:
Correction factor for ∆p 5.8 psi, f∆p = 0.72 Correction factor for liquid temperature fTliq = 0.92 Correction factor for Tdisch. 120°C , fdisch. = 0.95 Qn = Qo × f∆p × f Tliq × f Tdisch. = 18 × 0.72 × 0.92 × 0.95 = 11.3 TR
Te = 0°F Qo = 18 TR Tliq = 50 °F Max. ∆p = 5.8 psi Tdisch. = 120°F
From the capacity table a ICS 25-10 with Qn capacity 11.5 TR is selected.
The capacity table is based on nominal conditions (∆p = 3 psi, Tliq = 90°F, Pdisch.= 185 psi, Tdisch.= 180°F ) Therefore the actual capacity must be corrected to nominal condition by means of correction factors.
