Designed for optimized efficiency with flow approximately 10% greater than our nearest competitors. It ensures safe working pressure, even with the increased flow made possible by ERL pumps.
Used for liquid transfer in irrigation, general industrial, power generation, mining, storm water, snow making, and sump service. This valve will remain closed until the pressure overcomes the force of the respective set point spring. Made of cast ductile iron with stainless steel housings and impellers where required by the application. Available 4”x 6” and 6”x 8”, it features built-in lifting eye for convenient installation and repair.
Designed For Liquid Cargo Tank Barges
The ERL Pressure Relief Valve or Cargo Relief Valve is designed specifically for tank barges. ERL has optimized our valve to flow ~10% more than our competition. This ensures that your barge remains within safe working pressure when using the ERL high flow vertical turbine pumps. Available Inlet Flanges include: 150lb and 300lb
Meets 46 CFR 54.15-10 For Increased Flow Capacity Required For ERL Cargo Pumps
The ERL Pressure Relief Valve ensure the pressure does not exceed the “maximum allowable working pressure” of the barge, even with the increase flow available with ERL’s Cargo Pumps.
The ERL Pressure Relief Valve is design to automatically maintain safe design working pressure in your cargo discharge piping. This valve will remain closed until the pressure overcomes the force of the respective set point spring. Once this occurs, the valve will recirculate cargo back into the tank of the barge.
Stainless Steel Internals
The ERL Pressure Relief Valve internal parts are manufactured using 316, 17-4PH and 416 stainless steel to ensure extended service life.
Safe & Easy Lifting Eye
The ERL Pressure Relief Valve is the only PRV designed with a built in lifting eye. This provides a safe and easy method to install our valve on a tank barge.
Every ERL Pressure Relief Valve undergoes a set point pressure and a shell test at a board certified VR facility. Every ERL Valve is serialized and provided with documentation of the test. We also test and measure flow capacity at our in-house Pump Test Stand to verify the actual flow rate.
