The Pump Bypass Valve is of a fail open design, utilizing our DIN 2-way valve design. If air or electrical power is lost, the valve will go to the bypass position. In the bypass position, the DIN 2-way valve is in the open position, allowing flow to go over a series of orifices.
If Elwood's standard line of Pump Unloading Valves do not fit your system's requirements, please request a custom design and our team will design the valve to fit your needs!
