Overview
The Haskel 54492-1 is a precision air pilot valve engineered for high-pressure industrial applications. As a 2-way normally-open design with a seated poppet construction, it delivers virtually zero leakage at pressures up to 5000 psig. This valve is ideal for systems requiring accurate pressure regulation and reliable venting in pneumatic or gas-driven pump systems, boosters, and specialized industrial equipment.
Key Features
- 2-way normally-open configuration for fail-safe operation
- Seated poppet design ensures minimal leakage on liquids and gases
- Directly air-actuated—no electrical components required
- Compact, lightweight construction for space-constrained installations
- Compatible with air-driven pumps and booster systems
- Field-adaptable for solenoid actuation if electronic control is required
