Pneumatic Actuated Gate Valve

Pneumatic Actuated Gate Valve – Fail-Safe Pneumatic Operation for Emergency Shutdown Systems

Pneumatic Actuated Gate Valves combine gate valve isolation with spring-return pneumatic actuators providing fail-safe action (fail-open or fail-close) critical for African oil & gas safety systems, emergency shutdown (ESD) applications, and process safety instrumented functions (SIF) requiring guaranteed valve position on loss of instrument air. The pneumatic actuator responds rapidly (typically <5 seconds full-stroke) for emergency isolation.

Essential for African safety-critical applications from Nigerian offshore ESD systems to South African chemical plant safety instrumented systems (SIS), pneumatic actuated gate valves serve DN 50 to DN 900 (2″ to 36″) automated safety applications in Class 150-900 ratings per IEC 61508 (SIL rated). The fail-safe spring-return design guarantees valve position during power failures, instrument air loss, or emergency conditions—critical for African facilities requiring SIL 2/SIL 3 safety integrity levels and rapid emergency response.
