The VKM-20 valve (oxygen mains valve) is intended for installation in the rupture of the oxygen pipeline at P≤ 20 MPa (200 bar). It is allowed to be used in contact with cryptoproducts (N, Ar, O2, Kr, Xe …) and mixtures based on them, CO2 That’s it.
The diameter of thehose is 8 mm.
The valve body has two threaded plugs (M12x1.5) with a plug and a pressure gauge (25 MPa) installed in them. The plug with the pressure gauge can be changed for the convenience of monitoring the pressure in the main line. The VKM-20 valve is usually installed on the main branches of the central pipeline, which allows, if necessary, to block individual branches of the network without disconnecting other consumers.
