pressure control servovalve DS6

Description:
The Selec pressure control Servovalve DS6 keeps a Oilpressure constant. The pressure is electricaly controlled and adjustable up to 300 bar. Its switchtime is extremely short and therefore well known for highspeed reactiontime application. Max. flow at
pressuredifference of 5 bar = 30 l/min.



pressure control servovalve DS11

Description:
The Selec pressure control Servovalve DS11 keeps a Oilpressure constant. The pressure is electricaly controlled and adjustable up to 210 bar. Its switchtime is extremely short and therefore well known for highspeed reactiontime applications. Max. flow at pressuredifference of 5 bar = 50 l/min.
