- Specifications: DN15~DN400
- material: Silicon brass, stainless steel, cast steel
- Product description
Oxygen specific cut-off valve is made of silicon brass or stainless steel casting material, with high mechanical strength, wear resistance, good safety and so on. Used in the oxygen pipeline, with the best anti explosion flame retardant performance, eliminating the safety factors on the oxygen pipeline. The oxygen valve is forced to seal the valve, so when the valve is closed, the valve must be applied to the valve pressure to force the sealing surface does not leak. Oxygen valve is a kind of special valve of the oxygen pipe network. Stood in the city of liquefied petroleum gas reserves, the oxygen valve is also used in refinery, petroleum chemical plant, petrochemical plant of liquefied gas system, as a control device for opening and closing the closure of media.

3 valve installation, the body must be the direction of the flow arrow logo and the media flow to the media.
4 the installation of the valve can not affect the sealing performance of the valve, flange gasket should adopt PTFE or metal spiral wound gasket.
5 valve can not be installed near open flame and oil use point, and should be located in the protection cover does not produce sparks in.
6 grounding valve installation should have good equipment, the flange end of the guide screw holes must have a good grounding, in order to prevent static electricity.
7 on the installation of large diameter valves and pipes should be given enough support.
8 valve should be regularly maintained, maintenance or testing, to ensure the safety and sealing of the valve.
9 valve maintenance, repair, including the repair of the valve only by the manufacturer or other qualified units to perform.
