Buckling Pin Technology

< PRODUCTS /Model "W-B" – Actuator pilot for a differential set pressure source

The Model "W-B" pilot allows sensing a differential pressure source with a 316 piston, trim, and cylinder and at a differential set pressure, send clean fluids to a valve actuator through a 2- position – 3-way spool valve for a spring ended actuator or a 2-position – 5-way spool valve for a pressure-pressure actuator. This allows you to turn any quarter-turn valve into a relief valve or an emergency shutdown valve.

• The spool valve is sized for the actuator speed required.

• The spool valve can work with clean fluids to 250 PSI.

• The Buckling Pin spool pilot valve can have set points from 1 to 5,000 PSI differential pressure but is not adaptable for fluids that will solidify in the piston chamber.

ADVANTAGES: Excellent accuracy, simplicity(one moving part) and proven reliability. The sensing accuracy is +/– 5% of set point.

APPLICATIONS: Turn any quarter-turn valve into a relief valve or an emergency shutdown valve. Sense differential pressure across an orifice, filter or obstruction.

PROXIMITY SENSOR OPTION: Gives a remote indication of the pin buckling and the spool shifting.

RESETTING: To reset the pilot, vent the differential system pressure, remove the holding nut, discard the buckled pin, push the spool in, install a new pin, screw in the holding nut and put system differential pressure again on the Buckling Pin piston. Put the low differential pressure on first and then the high differential pressure.

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.
• No required replacing of pin yearly due to fatigue.
• 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.
