Overview
The Haskel 54492-1 is a 2-way normally open air pilot valve designed for pneumatically-actuated control in high-pressure hydraulic and fluid applications. Built by Haskel International, Inc.—a leading manufacturer of air-driven pumps, boosters, and precision pressure control components—this valve features a seated poppet design that provides virtually zero leakage at high pressures with low-viscosity fluids.
Key Features
- 2-way normally open configuration for direct air-actuated control
- Nominal area ratio of 55:1 with maximum inlet pressure of 5000 psig and Cv of 0.6
- Seated poppet design minimizes leakage on low-viscosity liquids
- Ideal for wet or hazardous environments with air-driven pump systems
- Optional electrical control via sub-miniature 3-way solenoid air valves
- Stainless steel, Buna N, and PTFE construction for corrosion resistance
