Fisher 377 pressure-sensing trip valve is used for control applications where a specific valve/actuator action is required when supply pressure falls below a specific point. 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 Series trip valve automatically resets, allowing the system to return to normal operation. The trip valve can be top-mounted on a manifold, yoke-mounted, or bracket-mounted to match the application requirements.
