Accu-Shear pin devices compliant with global code regulations that will protect yourself and your company. Our ASME certified Accu-Shear pressure relief devices have a revolutionary design that is different from other traditional Buckling Pin Devices and Valves like Rupture Pin, Buckling Pin, Rupture Disc and BPRV. The device does what its name implies; it shears or breaks the pin as opposed to compressing or bending the pin that you see in most pressure relief valves.

The Accu-Shear device opens and closes like a butterfly valve, and the pin is situated on the outside the device which allows for easy and efficient replacement. The Accu-Shear pin is designed to break cleanly every time. During the manufacture process, every fifth pin is broken to insure the material or tolerance has not changed. Our Accu-Shear pins are less costly than our competitor’s pins and are easily replaced without needing to tear down the entire system.
