ER/V

Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a flame. Emergency 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.

Function and Description

Highly Developed Pressure Relief Valve

The ER/V type PROTEGO® valve is a highly developed emergency pressure relief valve with high flow capacity. 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 emergency pressure relief for storage tanks, containers, silos, 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. ; it 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 impermissible product vapor loss close to the set pressure. It is designed to relief particularly large amounts to prevent the vessel Vessel Container or structural envelope in which materials are processed, treated or stored. from rupturing in an emergency case.

Full Lift Technology

The device will start to open as soon as the set pressure is reached and only requires 10% overpressure to full lift. Continuous investments into 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. This “full lift type” technology allows the valve to be set just 10% below the maximum allowable working pressure of the tank and still safely vent the required mass flow.

Advanced Manufacturing Technology

Due to the highly developed manufacturing technology, the tank pressure Tank pressure Tank pressure is the pressure within a tank. is maintained up to the set pressure, with a tightness that is far superior to the conventional standard. This feature is achieved by valve seats made of stainless steel with an inserted O-ring O-ring O-rings are ring-shaped gaskets with a round, o-shaped cross section seal Seal 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. , a precisely lapped valve pallet, as well as a reinforced housing design. After the excess pressure is relieved, the valve reseats and provides a tight seal again.
