Overview for 2WK Solenoid Valve
Solenoid valve model: 2WK
Valve material: all copper (valve copper + coil copper)
Applicable fluid: air, water, oil
Type: Normally open (ie: power on - close, power off - open)
Voltage: AC220V DC24V DC12V
Pipe size: 1 1/4 (1.2 inch)
Oil seal material: NBR (-5~100℃)
Pressure: 0~1.0MPA
Note: DC12V and DC24V Pneumatic Solenoid Valve should be equipped with 2A current supply, which is beneficial to the normal operation of the valve!
Solenoid valve outlet pipe water can not be reflued, if it will flow back, you need to install check valve.
