Nitrogen-oxygen shut-off ball valve, shut-off ball valve, ball valve

Product Introduction

The nitrogen and oxygen shut-off valves are specially designed for the nitrogen-oxygen system in coal gasification. They are special hard-sealed ball valves that can adapt to high temperatures, high pressures, high wear resistance, fire prevention, anti-static, zero leakage, and oil-free working conditions. 

Diameter range: NPS 2" ~ 12" (DN 50 ~ DN 300) 

Pressure rating: CLASS 150 - 1500 (PN16 - PN250) 

Main materials: F316, INCONEL, MONEL, etc. 

Connection method: Flange end 

Operating methods: pneumatic, hydraulic, etc. 

Application scope: Petroleum, chemical industry, natural gas, coal chemical industry, power industry, etc.

The nitrogen-oxygen cut-off ball valve is mainly used in gas liquefaction equipment, air separation equipment; natural gas liquefaction, storage and transportation equipment; liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide cryogenic storage tanks and tankers; pressure swing adsorption oxygen and nitrogen production equipment, etc.The nitrogen-oxygen cut-off ball valve is mainly used in gas liquefaction equipment, air separation equipment; natural gas liquefaction, storage and transportation equipment; liquid oxygen, nitrogen, argon, hydrogen, carbon dioxide cryogenic storage tanks and tankers; pressure swing adsorption oxygen and nitrogen production equipment, etc. It is used to cut off and conduct the medium, and can promptly cut off the medium in case of failure. It is used to cut off and convey the medium, and can promptly cut off the medium in case of failure. This valve has the advantages of simple structure, small size, light weight, reliable sealing, convenient operation, flexible opening and closing, wide applicability, etc. This valve has the advantages of simple structure, small size, light weight, reliable sealing, convenient operation, flexible opening and closing, wide applicability, etc. It is widely used in LO2, LN2, LAr, LNG, LHe and other cryogenic media, and has fire prevention, anti-static and explosion-proof functions.
