Assisted Lift Solenoid Valves
Assisted lift solenoid valves are a combination of a direct acting solenoid valve and a pressure assisted solenoid valve just that in this case the armature is now mechanically connected to a diaphragm typically by means of a spring, hence the term 'Assisted Lift'.
Vacuum Solenoid Valves
Assisted lift solenoid valves are often used within applications that include vacuum or very low pressure differential control points. Because of this they are sometimes referred to as Zero Pressure or Zero Rated solenoid valves.
Diaphragm Solenoid Valves
Assisted Lift solenoid valves often utilise a diaphragm to give them their special functionality. For this reason they are also often referred to as Diaphragm Solenoid Valves
