ZE/WU Sampling & Air Bleed Valve
Brand: PROTEGOThe Protego ZE/WU sampling and air bleed valve is used for flame transmission proof venting of pipelines and equipment that transports or processes flammable liquids, and for taking liquid samples.
The valve incorporates an end-of-line deflagration flame arrester. Should the gas/air mixtures or product vapor/air mixtures ignite during venting, the valve prevents flash back into the system to be protected.
The sampling and air bleed valve Protego ZE/WU consists of the threaded angle valve in pressure stage PN25 with hand wheel as standard design and female threaded connection (Pipe thread G 1/2" up to G 1") and the flame arrester with cover.
