Function
-M-Flow rate
1,200 … 2,900 l/min -Q-Temperature range –10 … +60 °C
-L-Operating pressure
2 … 10 bar/28 … 145 psi -W-
Solenoid actuated soft start valve for gradual pressure build-up in
pneumatic systems. This ensures safe start-up of pneumatic systems.
A minimal amount of air flows into the system via an adjustable flow control valve. Output pressure is built up slowly. Downstream cylinders and working devices are slowly advanced to their initial positions. When the output pressure reaches approx. 50%of the supply pressure, the valve switches to full flow. For F solenoid coils –12, 24, 42 V DC
–24, 42, 48, 110, 230, 240 V AC (50 … 60 Hz)
On-off valve in combination with service units
Manual override, detenting
-H-
Note
Manual override can be detented and secured in the initial position.In the depressed position, the man­ual override is advanced automati­cally to its initial position when the valve is actuated.
-H-
Note
Control voltage should not be switched to downstream solenoid valves until after pressure has been built up.
