Haskel 57175-60 Air Pilot Valve
Features & Benefits:
- Seated poppet or ball design for virtually zero leakage at high pressures with low viscosity fluids.
- They are NOT “bubble-tight” on gases.
- Normally-open models will generally hold a tighter seal on low viscosity liquids or gases because the seating force does not depend on the inlet pressure.
- Directly air-actuated for ideal system compatibility in wet or hazardous areas, or when used with air-driven pumps or boosters. Yet, if electronic or electrical control is preferred, they can be actuated with any of a wide selection of sub-miniature 3-way solenoid air valves available from many manufacturers.
- Employ the same basic area-ratio principle used in Haskel pumps, enabling high forces to be easily and directly controlled from low pressure plant main or instrument air.
- Although not normally considered for pressure control, all of the normally-open 2-way models can do double-duty in a circuit by also providing safety relief function simply by installing a small air regulator in the pilot line.
