2" Angle Type ESV
40 - 500 PSI, 2" NPT, Flanges Optional

Flowing pressure acting on the unbalanced stem area puts an axial force on the pin. At set point, the pin buckles and the valve closes for a bubble tight seal. In case of a downstream line break, the mass velocity impinging on the lower piston surface will force the pin to buckle and the valve will seal closed.

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
