- Ordering Process
The opening and closing parts of H41N natural gas lift check valve are opened or closed by means of medium flow and force. Polytetrafluoroethylene or nylon plastic is used as sealing surface material. The micro deformation of polytetrafluoroethylene or nylon plastic under medium pressure is used to improve sealing performance, slow down the impact of medium pressure and prevent static pressure. Electricity sparks, protects valves and pipes.
Main uses
Natural gas lift check valve is suitable for gas pipeline to control the opening and closing device for connecting and cutting pipeline medium to prevent medium countercurrent. Its role is to prevent natural gas, gas, gas, liquefied petroleum gas pipeline in the back flow.
Scope of use
Range: DN15 ~ DN300
Pressure range: 1.6MPa ~ 16.0MPa
Temperature range: -20 C ~ 200 c
Medium range: gas, natural gas, liquefied petroleum gas, gas and other inflammable and flammable gases.
Performance specification
