2" - 6" Inline ESV
40 - 1,440 PSI, 150#, 300#, 600#
RF Flanges

Flowing pressure acting on the stem area puts an axial force on the pin.
At set point, the pin buckles and the piston rapidly moves to a bubble tight closed position.

Advantages:
• Only one moving part, has extreme ..
..accuracy and proven reliability...

Additional Advantages:
• You get safety without venting
..pollution.
• No product loss by venting.
• No flare system required.
• No yearly valve testing.
• The pin obeys Euler's Law precisely
..and cannot fatigue.
• There is no set pressure variation
..with ambient temperature change
..on the pin.
• The precise pin is the sensor and
..the actuator.
• The standard accuracy is +/– 5%.
• Buckled pins can be replaced
..in minutes.
• The pin cannot fatigue
