In the role of a mechanical safeguard, a shear pin is a safety device designed to shear in the case of a mechanical overload, preventing other, more expensive or less-easily replaced parts from being damaged. As a mechanical sacrificial part, it is analogous to an electric fuse.

Jan 18, 2016 · Shear Pin Devices. A shear pin device is actuated by inlet static pressure. The device is designed to function by the shearing of a load-carrying pin that supports a pressure-containing member. The force of overpressure forces the pin to buckle and the device to open.

Shear pin devices offer many advantages over other types of devices. Once the device is set in the factory, changing the pins in the field is very simple. No nuts to adjust length of pin . No need to remove the device from the line.

Innovative unique patented PRD differ from traditional devices. It shears or break the pin rather buckling or bending the pin. The Accu-shear Devices’ high temperature ability and large diameters make it ideal for flare applications and other ‘rough’ services.

Often referred to as ‘Electronic Shear Pins’, ‘Torque Limiters’, or ‘Shock Relays’, these sensitive controls can monitor changing workloads and signal process changes and shut down motors to protect them from dangerous conditions. There are four models with varying capabilities that align to the most common applications.

“Accu-Shear” Shearing Pin Device At EnviroValve, we know there is a better way to design and build an industrial pressure relief device. We take pride in the fact that our innovative PRD technology offers real and practical benefits to our clients around the world.

The PRV utilizes shear pins to relieve overpressure during drilling and other operations. Hardened stainless steel stems and stainless steel liner subs provide improved corrosion resistance resulting in higher reliability and longer valve life.

May 5, 2017 · A very popular alternative to both rupture discs and ‘UV’ certified PRVs, the buckling pin device works similarly to a spring loaded PRV but has the spring replaced with a pin. Upon reaching the desired set pressure the pin buckles and allows to …

Feb 3, 2024 · Shear pins are mechanical devices that are designed to break or shear when a certain level of force is applied. They act as a kind of fuse, absorbing excess force and preventing it from damaging other parts of the equipment.

Ameridrives Power Transmission and Ameridrives Couplings shear pin devices are preset to release at a specified torque value in order to protect drive systems from expensive damage and lost production.
