A Shear Relief Valve is a type of valve consisting of one or two shear pins used to set the relief pressure. The shear pins are chosen from several standard-sized pins installed on the shear relief valve. A relief valve is a valve that controls the pressure in a system so as to avoid certain accidents like equipment failure.
Interflow in a Barksdale Shear-SealÂ® valve is a small amount of fluid flow from the Pressure A and B ports to the return port through the clearance between the rotor and the body. This interflow occurs whenever the valve is shifted from one position to another or when the valve is being used for throttling. This is due to the Shear-SealÂ® in the valve being only partially covered by the rotor. Interflow is not leakage and does not occur when the valve is fully engaged. The interflow in a Shear-SealÂ® valve is beneficial in that it reduces the hydraulic shock or âwater hammerâ that can occur when a. valve is closed rapidly. The small amount of interflow between ports acts as a cushion as the fluid flow is stopped in the system.
