The PROTEGO® ER-V-LP is a sophisticated emergency pressure relief valve specifically engineered for storage tanks, vessels, and silos where high flow efficiency is critical. Its primary function is to protect equipment from catastrophic failure by releasing large quantities of vapor in the event of an emergency, such as an external fire. Using patented "full lift type" technology, the valve begins to open at its set pressure and reaches its maximum flow capacity with only a 10% pressure increase. This allows operators to set the relief pressure significantly closer to the tank's maximum allowable working pressure (MAWP) compared to conventional valves, optimizing system pressure management.
A standout feature of the ER-V-LP is its exceptional tightness, which far exceeds standard industry requirements. By maintaining a superior seal right up to the set-to-operate pressure, the valve minimizes product loss and reduces environmental impact. The design is built for durability, featuring a sturdy, reinforced housing that protects the internal guided valve pallet from harsh weather and external environmental factors. It is suitable for use in explosion-hazardous areas and is widely considered a leading technology for API-compliant tanks.
