When continuously energizing adjacent valves at the same time, ambient temperature rises since the coil generates heat. Implement measures to exhaust excess heat so that the temperature remains within the range of the table on the right. Coil

Working Principle
Core
The armature is attracted to the core by electromagnetic force as the coil is energized. When the applied current varies, the attraction force also varies proportionally to it. The flow rate is controlled by the movement (stroke) of the armature, depending on the balance between this attraction force and the spring load.

Note) Sliding resistance at this point is the hysteresis of the flow.

Model Selection ∆P = (P1 – P2) MPa ∆P : Pressure differential P1 : Inlet pressure P2 : Outlet pressure
Condition 1. P1 = 0.7 Mpa, P2 = 0 MPa (Atmospheric pressure) Refer to curve A when ∆P is 0.7 MPa.
Ex) At increasing current, the flow rate when 140 mA current is applied is 85 L/min. (See q.) If current decreases at this point, the flow rate may not change by 135 mA due to hysteresis. (See w.) The flow rate at increasing current and decreasing current are not the same due to hysteresis. (q 85 L/min., e 93 L/min.) Condition 2. P1 = 0.7 MPa, P2 = 0.2 MPa Refer to curve B when ∆P is 0.5 MPa. Ex) At increasing current, the flow rate when 150 mA current is applied is 65 L/min. (See r.) If the outlet pressure P2 increases by 0.15 MPa, ∆P decreases by 0.15 MPa and becomes 0.35 MPa (See curve C), and the flow rate when the same current is applied is 40 L/min. (See t.) • The flow rate decreases due to change (increase) in outlet pressure, even if the inlet pressure and current value are the same. Condition 3. In a vacuum • For vacuum specifications, the operating pressure range is from 0.1 Pa·abs to max. operating pressure differential. • A(2) port is applicable with vacuum pressure.

Q. Required flow rate = 0 to 75 L/min. P1 = No conditions, P2 = 0 MPa (Atmospheric pressure) In this case, all orifice sizes of PVQ30 series satisfy the required flow rate. (Flow rate when rated current is applied) The table below shows the pressure differentials to satisfy the required flow rate. In the flow rate characteristic charts, a pressure differential over the flow rate indicated by the dashed line (75 L/min.) up to the max. operating ARJ pressure differential will satisfy the required flow rate.

Note 1) Ambient temperature is for the valve proximal section (approx. 1 mm). When the valve is continuously energized at an ambient temperature of 50°C (when applying maximum current), the coil outer surface reaches 90°C. The temperature changes depending on the operating conditions, and the coil outer surface temperature must be kept at 90°C or lower. Note 2) Maximum operating pressure differential indicates pressure differential (difference between inlet and outlet pressure) which can be allowed for operation with the valve closed or open. If the pressure differential exceeds the max. operating pressure differential of orifice, the valve may leak. Note 3) For vacuum application, max. operating pressure range is 0.1 Pa·abs to max. operating pressure differential. A(2) port is applicable for vacuum pressure.

Glossary Proportional control Control the fluid proportionally according to input signal (current).
Max. operating pressure differential Indicates max. pressure differential (difference between inlet and outlet pressure) which is allowed for operation with the valve closed or open.
Max. operating pressure This indicates the limit of pressure that can be applied to the inlet. (The pressure differential of the proportional valve must be no more than the maximum operating pressure differential.)
Orifice diameter Diameter of the hole for sealing the valve body of the proportional valve. This does not indicate the effective cross section.
Hysteresis Greatest flow rate difference between current increase and current decrease (with the same current). (Percentage divided by max. flow rate)
Repeatability Deviation of output flow rate when the same current is applied. (Percentage divided by max. flow rate)
Start-up current Current at which the flow rate is actually output while increasing current from zero. (Percentage divided by rated current)

Caution
Operation in Vacuum
Caution
ARJ
This product makes proportional control possible with constant current.
When the product is used in vacuum, apply vacuum pressure to A (2) port.
If controlled with voltage, the output flow rate cannot be kept constant due to current fluctuation. Use stable DC power source of sufficient capacity without much ripple.
The pressure at P(1) port should be larger than the pressure at A(2) port.
Handling
Caution 1. This product is adjusted to the respective specifications at SMC factory before delivery. Do not disassemble the product or remove parts as it could cause breakdown of the product.
2. Flow rate is controlled by balancing the valve body. Do not expose the product to external vibration and impact as it changes the flow rate. Vibration may occur depending on the piping conditions or control methods.
Pressure Difference
Caution Leakage from the valve may be caused if the pressure difference is larger than the maximum operating pressure differential of the respective models.
