In 1986, Shell and Exxon came to Mr. Julian Taylor of Taylor Tools and asked him to solve a serious problem with pilot operated valves that were failing to operate 5% of the time. The set pressure was 83 bar (1220 psi) and the tolerance was +/-1.5%. This tolerance was not possible with conventional methods. \r\n\r\nMr. Taylor developed the Rupture Pin pressure relief valve. This Rupture Pin valve was used in parallel with the existing pilot operated valves. He used Euler#s Law of Compressed Columns to meet the stringent requirements handed to him. \r\n\r\nAfter meeting the challenge presented and obtaining approval of ASME Section VIII, paragraph UG 127(c), Code Case #2091-3, for Buckling Pins, volume sales of the Rupture Pin Valve started in 1990. With the need for pressure relief of slurries and more viscous fluids requiring full flow orifices, Mr. Taylor developed the Buckling Pin valve in 2002. The Buckling Pin valve closes to isolate pressure, which can be accomplished with a piston, flapper, or any quarter-turn valve.\r\n\r\nToday Rupture Pin Technology and Buckling Pin Technology are located in Oklahoma City, Oklahoma. They are still owned and operated by Mr. Taylor and enjoy an honored and excellent reputation in the pressure relief and emergency shutoff business. Our customers come to us for solutions to problems with any pressurized system, whether it is relief or shutoff. Over 13,650 valves have been sold through trained independent representatives around the world and have a remarkable 99.9% customer satisfaction rate.\r\n\r\nvisit us at www.rupturepin.com; www.bucklingpin.com; or www.taylorvalve.com
