Pilot-operated, three port, two position poppet valve with a spring-return action
Low friction fluid seals used for all dynamic sealing
Wide range of pilot supply pressures
NACE Standard MR-01-75 compliant

Master shutdown valve Type 1175 is a pilot-operated, three port, two position poppet valves with a spring-return action.

Manufactured from materials complying with NACE Standard MR-01-75 (latest revision as applicable), the valve can be used in many oil field and gas field applications. The piston-type pilot section of the valve is equally versatile, responding to a wide range of pilot supply pressures and any one of a variety of hydraulic operating media.

With the valve unoperated, Port 3 is connected to Port 5, while Port 4 is isolated. Pilot pressure, applied above the piston, displaces the valve stem, interconnecting Ports 3 and 4 and isolating Port 5. Low friction fluid seals are used for all dynamic sealing so that the valve can be connected for either normally-open or normally-closed operation.
