P/ELR

The Pressure/vacuum relief valve Pressure/vacuum relief valve is an umbrella term that includes pressure or vacuum relief valve as well as pressure and vacuum relief valve. P/ELR Type PROTEGO® valve is a highly developed pressure relief valve Pressure-relief valve Valve designed to open and relieve excess pressure and to reclose and prevent the further flow of fluid after normal conditions have been restored. with excellent flow performance. It is primarily used as a device Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. for relieving pressure Relieving pressure The relieving pressure is the vacuum or overpressure at which the valve reaches the lift required for the mass flow to be discharged. in tanks, containers, and process engineering equipment Equipment Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion. . The valve offers reliable protection against overpressure Overpressure Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. and prevents excessive loss of product Product Includes equipment, protective systems, devices, components and combinations of these. vapors close to the set pressure Set pressure Set pressure is the gauge pressure at the device inlet at which the relief device is set to start opening under service conditions. . The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to full lift Lift Lift is the actual travel of the valve pallet from the main valve out of the closed position. . Continuous investments in and a commitment to research and development have allowed PROTEGO® to develop a low pressure valve which has the same opening characteristic as a high pressure safety relief valve. With this “Full Lift Type” technology, valve can be set at just 10% below the maximum allowable working pressure of the tank and still safely vent the required mass flow.

The optimized fluid dynamic design of the valve body and valve pallet Valve pallet Valve pallet is the generic term for the assembly that rests on the valve seat. is a result of many years of research, resulting in a stable operation of the valve pallet, optimized performance, and reduced product losses.
