Product Description
Pneumatic Emergency Shutdown Ball Valves (ESDV)
Emergency shutdown valves (ESDV) are critical safety components designed to rapidly isolate fluid flow in pipelines during hazardous situations. These pneumatic-actuated ball valves provide reliable emergency protection for oil, gas, and industrial process systems.
Critical Safety Features
Zero Leakage Performance
Designed to meet API 508 and ISO 5208 standards for seat leakage testing, ensuring minimal to zero leakage when closed.
Fire-Safe Construction
Certified to API 607, API 6FA, and BS 6755 Part 2 standards, these valves maintain operational integrity during external fire exposure.
Rapid Emergency Response
Quarter-turn ball valve design enables fast closure within 10 seconds of activation, with full open-to-close timing of 1-2 seconds per inch of valve size.
Flow Optimization
Full bore design minimizes pressure differential and turbulence, functioning virtually like a straight pipe section during normal operation.
Fail-Safe Operation
Pneumatic spring-return actuators ensure automatic closure during power or pressure loss, with manual field reset capability for safety verification.
