Innovative unique patented PRD differ from traditional devices. It shears or break the pin rather buckling or bending the pin


  


Ideal for flare applications

The Accu-shear Devices’ high temperature ability and large diameters make it ideal for flare applications and other ‘rough’ services. The metal seals allow for an extremely repeatable and robust Device that is unmatched in the industry.



Butterfly Style Device

Butterfly style design creates faster pressure relief and more efficient use of pipe layout that might allow for reduced valve size and project cost.



Robust Design

ASME Certified Accu-Shear Device is made of high-quality materials and precision machined components. It is simple and direct in its design with a minimum amount of parts, resulting in reliable operating performance



ASME UD Stamped

Accu-Shear is ASME certified ensuring consistency of our manufacturing and testing processes. Each device is rigorously tested with three test reports supplied on each shipped device



Fast Reset Times

Accu-Shear resets manually in seconds with easily replaceable pins-Virtually NO DOWNTIME for the entire line and low labour cost to reset (requires one person and a crescent wrench).



Preload Pin

A preloaded pin allows for operational pressure variances in the line, fluctuating over time, without the fatiguing of the pin and thus maintaining an accurate tight release. The patented triple offset seal and associated pre-load technology of the AccuShear results in: More reliable performance as un-predictable seating and breaking frictional forces are nearly eliminated.



Accurate Burst Pressure

Pins are set to exacting standards and meet a wide range of process requirements. Between 15 PSI to 45 PSI. Accurate Release: +/- 5% – every time!



Multiple Valve And Seal Trims

Accu-Shear devices are available in a variety of materials and seal trims to ensure compatibility with your process the device can handle wide temperature ranges, corrosive material, and other obstacles.

The industry proven seal design (based on metal seated triple offset butterfly valves) allows for metal, Teflon or other seal materials to be used interchangeably with no adverse effects on performance or design.
