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 of using Buckling Pin ESV's are as follows:
• 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 beauty of our system is in its simplicity. (In many, there is only one moving part and
.....in all designs, the precise pin is the sensor and actuator.)
• The standard accuracy is +/- 5%.
• Buckled pins can be replaced in minutes.
• Replacement pins are relatively inexpensive and, if ordered from the factory before noon,
.....they can be shipped the same business day.
