Solenoid Valves

Servo and Pressure Assisted Solenoid Valves

Servo Pressure Assisted Solenoid Valves

2 way pressure assisted solenoid valves utilise the pressure differential (higher inlet pressure against outlet pressure) to move the diaphragm or piston via pilot control.

With the inlet pressure P1 and the valve de-energised the pressure of the media forces the diaphragm or piston tight against the outlet orifice closing the solenoid valve and preventing flow.

When energised the coil lifts the armature opening an internal pilot hole allowing the pressure above the diaphragm or piston to be released downstream allowing the inlet pressure lift the diaphragm or piston into the open position allowing full flow of media through the valve to P2.  These valve must have at least the required minimum stated pressure differential (difference between inlet and outlet pressure) to operate correctly and are ideal for open to atmosphere and higher pressure systems.

Benefits of servo assisted solenoid valves:

2 way servo assisted solenoid valves typically offer higher flow, reduced cost (especially for larger valves above DN25); power consumption and heat generation giving advantages for most media applications and can be found in either Brass, Bronze, Ductile or Cast iron, Stainless Steel and Plastic bodied variants.

Other associated names for Servo Assisted solenoid valves are:

Servo Assisted Solenoid Valves - Pressure Assisted Solenoid Valves, Floating Diaphragm solenoid valves, Floating Piston solenoid valves, media assisted solenoid valve, differential pressure solenoid valve, Pilot operated solenoid valve.
