P/EB

The Deflagration-Proof and Endurance-Burning-Proof P/EB 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 an integrated Flame Arrester Unit. 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 flame transmission-proof Flame transmission-proof Characteristic of a device to avoid flashback. out-breathing on tanks, containers, and process 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 product losses almost up 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. , while at the same time protecting against atmospheric deflagration as well as endurance burning Endurance burning Stabilized burning for an unlimited time. . The PROTEGO® Flame Arrester Unit is designed to achieve minimum pressure losses with maximum safety. The PROTEGO® P/EB valve is available for substances in explosion group IIA (NEC group D MESG > 0.90 mm).

This feature isensured by the valve seats made of high quality stainless steel and with individually 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 a 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 them from sticking when sticky substances are used and to enable the use in corrosive fluids. After the overpressure is released, the valve re-seats and provides a tight seal.

The valve can be used at an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F and meets the requirements of European Tank Design Standard EN 14015 (Appendix L) and ISO 28300 (API 2000). EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
