Function and Description
Highly Developed Pressure Relief Valve
The PROTEGO® Type ER-V-LP valve is a sophisticated pressure relief valve for applications in which a high flow efficiency is of the essence. It is primarily used as an emergency pressure relief valve on storage tanks, vessels, silos, and process engineering equipment. It offers reliable protection against excessive overpressure and prevents excessive product loss at pressures as high as close to the set pressure. It is designed to release particularly large quantities to prevent the vessel from rupturing in an emergency case.
Patented Valve Pallet Technology
The valve will start to open as soon as the set pressure is reached and only requires a 10% pressure increase or opening pressure differential until full lift. Continuous investments in and a commitment to research and development have enabled PROTEGO® to develop a New Valve Pallet Technology for which a patent has been granted. This Patented Valve Pallet Technology enables the typical safety valve characteristics to be applied to low pressure ranges while also maintaining a low leakage rate.
Adopting this new patented Valve Pallet Technology permits the valve to be set to just 10% below the maximum allowable working pressure of the tank and still vent the required flow.
Advanced Manufacturing Technology
Due to the sophisticated manufacturing technology, the tank pressure is maintained up to the set pressure, with a tightness that is far above the common standards. Once the excess pressure is released, the valve re-seats and seals tight again.

Diagrama de flujo volumétrico
Los diagramas de flujo volumétrico han sido determinados con un banco de pruebas de caudal calibrado y certifi - cado por TÜV. El flujo volumétrico V. en [m³/h] y el CFH se refi eren a las condiciones estándar de referencia de aire según ISO 6358 (20°C, 1bar). La conversión a otras densidades y temperaturas están referidas en el Vol. 1: “Fundamentos Técnicos”.
