3 way valve with pressure control

For hydraulic oils, lubricating oils, fuel oils and cooling lubricants emulsions.


Control is with pneumatic circuit:

• ON / OFF function changes from free discharge to regulated pressure

• max pressure is controlled setting the pneumatic pressure

• pneumatic control-setting group can be also remote mounted from - valve (suggested max 1 m tube).

• option: proportional control valve pressure and on-off fuctions controlled by PLC or external control
