The PROTEGO® sampling and air bleed valve Sampling and air bleed valve A deflagration-proof sampling and air bleed valve can be used both for manual venting of system components and for extracting samples of flammable liquids. is used for flame transmission-proof Flame transmission-proof Characteristic of a device to avoid flashback. venting of pipelines and 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. that transports or processes flammable liquids and for taking liquid samples. The valve incorporates an end-of-line deflagration Deflagration Explosion propagating at subsonic velocity (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. . Should the gas/air mixtures or product Product Includes equipment, protective systems, devices, components and combinations of these. vapor/air mixtures ignite during venting, the valve prevents flash back into the protected system.

The simple and sturdy design makes it suitable for nearly all flammable liquids. This 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. can be installed in any position. Flame transmission protection is guaranteed against atmospheric deflagrations of gas/air mixtures or product vapor/air mixtures of explosion Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. groups up to IIB IIB (NEC group D to C) up to an operating temperature Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. of up to 1.1 bar / 15.9 psi.
