ORI is the authorized representative for Rupture Pin Technology, Inc. based in Oklahoma, USA for the whole European market, including sales and after market activities.
ORI has promoted Rupture Pin valves in the Italian market for several years, and has been awarded key contracts for the supply of buckling pin valves; primarily for the overpressure protection of flare systems.

 

Rupture Pin Technology invented the buckling pin valve in 1986, commercial sales started in 1990.  The buckling pin technology has proven itself over the years and is specified by more and more engineering companies and end users, especially as the most reliable overpressure protection system for larger valve applications. 

Rupture Pin Technology shipped it's 10,000th custom manufactured valve in February of 2006.

 

 

The Rupture Pin Technology buckling pin valve can be used as pressure relief or emergency shutdown (shutoff) with predetermined accuracy and dependability.  The valve consists of a piston or plunger on seat, restrained from movement by a slender round pin, the buckling pin.  The piston (plunger) is the only moving part and will maintain a bubble tight seal while under pressure. 

The pin will buckle at a predetermined set pressure from an axial force created by the system pressure acting on the piston.  When the pin is buckled, at set pressure, the action of the valve to fully opened (or closed) is extremely rapid even more than a rupture disc.

The Rupture Pin valve is self contained and self actuating.  The pin is held by both ends with close tolerance inserts and is external of the system; therefore not affected by system conditions.

 

An alternative design is to use the Rupture Pin Valve as switching pilot for the operation of pneumatic actuators, specially in use with butterfly valves. This innovative design is being used in very aggressive processes like sea water or wet H2S or CO2.

 

The Rupture Pin Technology buckling pin valves are available in sizes from 1/8" to 48" in any materials of construction that is compatible to your system.
