Oliver Valves Instrumentation Check Valves – 3/8” to 1”, 6000 & 10000 PSI, UK

Oliver Valves instrumentation check valves are engineered for precision control in high-pressure instrumentation systems where unidirectional flow and protection from backflow are essential. Manufactured in the UK, these valves are available in sizes ranging from 3/8” to 1” and can operate under pressures up to 6000 PSI and 10000 PSI. Constructed from robust materials such as stainless steel (typically 316 SS), these check valves feature a spring-loaded poppet mechanism to ensure a fast and reliable seal under back pressure conditions. Their compact and rugged design is ideal for panel-mounted or inline applications in oil & gas, chemical, and hydraulic systems. These valves are well-suited for both liquid and gas services where clean and leak-tight operation is required.
