Flame Arrester Condensate Drain on Valves
The PROTEGO® ZE/TK condensate drain valve is used for flame transmission-proof Flame transmission-proof Characteristic of a device to avoid flashback. condensate drainage of devices or plant 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. (e.g., tanks, pipelines, etc.) where flammable liquids can form condensate and flammable product Product Includes equipment, protective systems, devices, components and combinations of these. vapor/ air mixtures could develop. They can also be used for the venting of tanks, plant components, and pipes that transport or process flammable liquids. The drain valve incorporates an End-of-Line Deflagration Flame Arrester Deflagration flame arrester Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester. .
Main Component – PROTEGO® Flame Arrester Unit
The Condensate Drain Valve PROTEGO® ZE/TK consists of the ball valve Ball valve A ball valve is a flow control device which uses a drilled ball to control flow of the medium. (1) with hand lever (2), a female threaded connection (e.g., pipe thread G½” up to G1”), and the 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. (3) with cover (4). The elbow fitting (5) is also available as an optional outlet. The Flame Arrester (3) consists of the flame arrester casing and FLAMEFILTER®. The ball valve is opened with the hand lever. When draining condensate, a suitable container is required. When draining flammable and/or toxic products, observe the appropriate safety provisions.
For Explosion Group IIB
The simple and sturdy design is suitable for nearly all flammable liquids and can be installed in any position. Flame transmission protection is guaranteed against atmospheric deflagrations of 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 (NEC groups 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 operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 1.1 bar/15.9 psi. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
