Qigao cast steel gate valve

Cast steel gate valve
: It is one of the most commonly used cut-off valves. It is mainly used to connect or cut off the medium in the pipeline and is not suitable for regulating the flow of the medium. Cast steel gate valves are suitable for a wide range of pressure, temperature and diameter, and are especially suitable for medium and large diameter pipelines. Nominal size D~D Nominal pressure.~. The sealing surface is made of asbestos graphite or flexible graphite. The working temperature is ℃. The operating modes include manual, gear transmission, electric, pneumatic, etc. It is suitable for water, steam, and oil medium pipelines. Product Features
. Compact structure, reasonable design, good valve rigidity, smooth passage and small flow resistance coefficient.
.The sealing surface is made of stainless steel or carbide and has a long service life.
.Using asbestos graphite or flexible graphite sealing, reliable operation, light and flexible.
. Various piping flange standards and flange sealing surface forms can be used to meet various engineering needs and user requirements.
.Widely used in pipelines of various systems in petroleum, chemical industry, hydraulic and thermal power stations.
