DR/ES-V

PROTEGO® DR/ES-V 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. Series uniquely combines the function of an In-Line Detonation Detonation Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). Flame Arrester 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. with the function of a 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. in one 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. . The device protects against deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). and stable detonation Stable detonation A detonation is stable when it progresses through a confined system without significant variation of velocity and pressure characteristics. . The weight-loaded pallet type valve (5) integrated in the shock absorber Shock absorber A shock absorber is a device that reduces the kinetic energy of a detonation. (1) of the In-Line Detonation Flame Arrester is designed as a pressure relief valve. 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. of the valve is adjusted in the factory and can range from 2 to 35 mbar (0.8 to 14 inch W.C.). After the pressure increases 40% from its set pressure, the valve completely opens to yield the maximum volumetric flow.

The PROTEGO® Flame Arrester Unit (2) consists of several FLAMEFILTER® discs and spacers firmly held in the FLAMEFILTER® casing FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. (4). The gap size and number of FLAMEFILTER® discs depend on the operating conditions of the flowing mixture ( explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. group, pressure, temperature). This device is available for explosion groups from IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm). The standard design is approved for an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F and absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 1.2 bar / 17.4 psi. Devices with special approval for higher pressures and temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
