Main features
Non-rising stem design: the stem does not move with the lifting and lowering of the gate, which reduces the overall height of the valve and saves installation space.
Excellent sealing: soft sealing or metal sealing technology is adopted to ensure the sealing performance of the valve in the closed state and prevent media leakage.
Strong corrosion resistance: stainless steel has excellent corrosion resistance, can resist the erosion of a variety of chemical media, to extend the service life of the valve.
High strength and pressure resistance: stainless steel and precision manufacturing process makes the valve has high strength and pressure resistance, can withstand high working pressure.
Easy to operate: provide manual, electric, pneumatic and other operating methods to meet the operating requirements of different working conditions.
Application Areas
Stainless steel non-rising stem gate valve is widely used in the following fields:
Petroleum, natural gas industry: used for oil and gas pipeline system in the medium cut-off and regulation, to ensure the safe operation of the pipeline system.
Chemical industry: in the chemical production process, used to control the flow of various corrosive media, to prevent media leakage and pollution.
Water treatment industry: used in urban water supply, drainage system cut-off and regulation, to ensure the rational use of water resources and emissions.
Power industry: It is also used in the fluid control system of thermal power plants, nuclear power plants and other occasions to ensure the normal operation of power equipment.
Technical specifications and materials
Technical specifications and material selection of stainless steel non-rising stem gate valves vary according to manufacturers and product models, but generally include the following:
Range of specifications: including a variety of through diameter specifications, such as DN15 to DN1000, etc., to meet the needs of different piping systems.
Material selection: valve body, valve cover and other key components made of stainless steel (such as 304, 316, etc.), the gate and seat according to the characteristics of the medium to choose the appropriate sealing material (such as rubber, PTFE, etc.).
Operation mode: manual, electric, pneumatic and other operating modes can be selected.
Connection: flange connection, butt-welding connection and other connection methods can be selected.
