Function and Description

Highly Developed Pressure Relief Valve

The P/ELR Type PROTEGO® valve is a highly developed pressure relief valve Soupape de surpression 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 Appareil 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 Pression d'ouverture 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. The valve offers reliable protection against overpressure Surpression Overpressure refers to an increase in pressure in a system or vessel above the normal operating pressure. and prevents excessive loss of product vapors close to the set pressure Pression de réponse 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 Course 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.

Advanced Manufacturing Technology

Due to our highly developed manufacturing technology, the tank pressure Pression de la cuve Tank pressure is the pressure within a tank. is maintained up to set pressure with a tightness that is far superior to the conventional standard. This feature is achieved by valve seats made of high quality stainless steel and with precisely lapped valve pallets (1), or with an air cushion seal Joint A seal prevents or limits unwanted transfer of product from one container to another. Seal is used as superordinate term for all types of sealing elements. (2) in conjunction with high quality FEP diaphragm Membrane A diaphragm is a thin layer of material, which has a large surface area. . The valve pallets are also available with a PTFE seal to prevent the valve pallets from sticking when sticky products are used and to enable the use of corrosive substance. After the overpressure is released, the valve re-seats and provides a tight seal.

Optimized Valve Design for Maximum Performance

The optimized fluid dynamic design of the valve body and valve pallet Clapet 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.
