The PROTEGO® ER/V is a high-performance emergency pressure relief valve designed for storage tanks, containers, and process engineering equipment. Similar to the "LP" version, it utilizes "full lift type" technology, meaning the valve achieves its maximum discharge capacity with only 10% overpressure above the set point. This high flow capacity is critical for emergency scenarios, such as external fire exposure, where large volumes of vapor must be vented rapidly to prevent the vessel from rupturing.
A key advantage of the ER/V is its superior seal integrity, which significantly reduces product evaporation and environmental pollution by maintaining tightness right up to the set pressure. The valve pallet is securely guided within a reinforced housing, protecting it from harsh weather and ensuring reliable operation in explosion-hazardous areas. Available in a wide range of sizes (DN 200 to DN 700) and materials like stainless steel and aluminum, it represents a best-in-class solution for pressure management in API-compliant tank systems.
