Product Range Features (Diaphragm Type)

■ Manual valves (push button type) 825

● Reliable operation Uses diaphragm construction that enables quick and sharp switching peculiar to this type. The valve seat is also reliable. ● Trouble free structure An extremely simple structure and a poppet-type seat method ensures freedom from galling, even if a certain amount of dust intrudes inside. Moreover, it will not stick even after being left unused for long periods. ● Can be used without lubrication. No sliding parts, and lubrication is unnecessary, and no breakdown problems due to inadequate lubrication. ● Any mounting direction is acceptable. This structure ensures operations without a hitch, no matter what the mounting direction is. ●Compact and lightweight An original compact design, and a light aluminum alloy body.

● Using nuts enables compact installation on panels (125P, 125HO types). ● Can also hold the pressed-down condition (125HO type). ● A vacuum valve with a non-leakage structure is also available.

Applications ● ON/OFF for pilot air ● Operation for single acting air cylinders and air grippers ● Filling or exhausting of air tank ● ON/OFF for air supply (125HO) ● ON/OFF for air jet and air blowing

■ Foot valves 829

● A holding mechanism maintains the unit in an operating condition, which can then be released by pushing a foot-operated latch located back of the pedal (250FL, 250-4FL, 25034FL).

Applications ● Operation for double acting air cylinders and air grippers ● ON/OFF for pilot air (Double air-piloted valve)

823

826

● Using nuts enables compact installation on panels (125V). ● A vacuum valve with a non-leakage structure is also available.

Applications ● ON/OFF for pilot air ● Operation for single acting air cylinders and air gripper ● Filling or exhausting of air tank ● ON/OFF for air supply ● ON/OFF for air jet and air blowing

■Mechanical valves (ball-cam type) 831

● Using nuts enables compact installation on panels (125B). ● A vacuum valve with a non-leakage structure is also available.

■ Manual valves (lever-operated type 3-position, 5-port) 827

● Operation of double acting air cylinders and air grippers (In the neutral position, the air cylinder and air gripper are in the free condition, and can be operated manually). ● A vacuum valve with a non-leakage structure is also available.

●ON/OFF for pilot air ●Operation for single acting air cylinders and air gripper ●Filling or exhausting of air tank ●ON/OFF for air jet and air blowing

828

● Sliding valve construction, and manually switched 4-port valve. ● Rotary type (swing lever) for reliable switching.

Applications ● For switching air cylinders

Applications ● Switching of pilot air ● Switching of air supply

■Mechanical valves (roller-cam type) 832

● Sturdy structure capable of withstanding harsh operation. Offers smooth pilot air switching.

Applications Applications

■ Manual valves

● ON/OFF for pilot air ● Operation for single acting air cylinders and air gripper ● Filling or exhausting of air tank ● ON/OFF for air jet

■ Micro valves 833

● Both normally closed and normally open types are available for 2-port and 3-port valves, to ensure applications of using every type of pneumatic signal. ● Virtually no change in operational force from low to high pressure range. ● No neutral position means smooth switching between the A port and R port.

Applications ● Confirms operations in pneumatic control circuits. ● Switches air pressure signals. ● Operation of air cylinder ● Filling or exhausting of air tank

When attaching a muffler on the R port

The cam acting direction of the roller-cam type (KMC) and one way roller-cam type (KMO) can be changed for use according to the piping requirement.

︵

For products with a special fitting (Rc1/8) on the 3(R) port, a muffler can be mounted to the 3(R) port, or piping can be connected to exhaust to the outside.

● While normal mounting uses 2 mounting holes of φ4.4 [0.173in.] on the body, use the neck for mounting when not using the roller plunger type in “pushed by load” applications. ● Since the exhaust hole is on the bottom surface of the valve body, leave a clearance of about 1mm [0.04in.] to avoid restricting exhaust. ● Always use the straight plunger type in “pushed by load” applications. ● While the cam and dog shapes normally set θ at about 30°, θ should be set even smaller when the speed reaches 500mm/s [19.7in./sec.] or more. ● For the valve strokes, see the table on p.834.

Micro valve mounting overview, and cam and dog shapes

Avoid over-tightening the R port fitting. For piping work, use a wrench to hold the fitting and prevent it from rotating.

Lubrication How to use as a divider valve

The 3-port, normally open type can be used as a divider valve. Let air in from the 2(A) port to flow toward the 1(P) port when OFF, and toward the 3(R) port when ON.

For this micro valve, use Turbine Oil Class 1 (ISO VG32). Depending on the piping conditions (length, height) etc., oil may fail to reach the micro valve. When it occurs, consider supplying turbine oil into the piping at periodic intervals.

2 （A） Flow (when OFF)

Dust protection 2 （A） Flow (when ON) Notes: 1. Avoid using the normally closed type as a divider valve. 2. When using as a divider valve, the Order Code is “-11-60.” Example: Roller-cam type divider valve KMC-11-60

Use appropriate protection when using the micro valve in locations subject to heavy dust, powder, machining chips, etc.

Micro Valve Parts Configuration
