Fisher 377 Pressure-Sensing Trip Valve
Fisher 377 trip valves help you maintain normal process operation in applications where a specific valve or actuator action is required. When supply pressure falls below the trip point, the trip valve causes the actuator to fail up, lock in the last position, or fail down. When the supply pressure rises above the trip point, the 377 trip valve automatically resets, allowing the system to return to normal operation.
Features
- Fisher 377 Pressure-Sensing Trip conversion to any of the fail modes requires only minor hook-up changes.
- The trip point is adjustable for specific supply pressure requirements.
