Flowline pilot valves

For safety control systems to switch pneumatic or hydraulic control pressure on rising or falling flowline pressures
Pilot-operated, three port, two position valve with a spring-return action
NACE Standard MR-01-75 compliance


These flowline pilot valves are pilot-operated, three port, two position valves with a spring return action. The pressure at which the valve functions is variable by adjusting the spring force – a wide range of pressure settings is covered by using seven interchangeable sensing head assemblies.

The pilots can be supplied with either nomally open or normally closed slide configurations, and function with a "block before bleed" action. The pilots are used to switch a pneumatic or hydraulic control pressure on rising or falling flowline pressures in pipeline valve and wellhead safety control systems.

Construction materials, predominantly 316 stainless steel and CA104 aluminium-bronze, and seals of fluoroelastomers and PTFE materials ensure high corrosion resistance and comply with NACE Standard MR-01-75 (latest revision as applicable).
