Pressure Balance Type Double Plug Valve
Product Description The KOSEN Pressure Balance Type Double Plug Valves is a valve that opens and closes the closing part (the stopper) rotating around the center line of the valve body. Plug valves are mainly used for cutting, distributing and changing the direction of media flow in pipelines....
The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
Oil lubricated hard seal cock valves can be divided into conventional oil lubricated plug valves and pressure balanced cock valves. A special grease is injected from the top of the plug into the valve body between the cone hole and the plug body to form oil film to reduce the valve opening and closing torque and improve the sealing and service life. Its working pressure can reach 64MPa, the maximum working temperature can reach 325 degrees, and the maximum diameter can reach 600mm.
Product features1. It has excellent high and low temperature performance, good pressure resistance, not curing, not dissolved, not dispersed characteristics.
2. It has the advantages of excellent tightness, adhesion and lubricity, very low volatile loss.
3. It is featured of excellent water resistance, electrical insulation and chemical stability, non - toxic, tasteless, resistant to ozone and weather aging.
4. It is material adaptable and has wide temperature scope when using, the suitable temperature range: - 40 ~ + 200 ℃.
It is suitable for insulation of motor and electron, seal of semiconductor, waterproof, conductive and flashproof of electrical insulator, high-voltage electronic connection system and electrical equipment which prevent moisture from entering, release and eliminate arc of corona, and can also be used for film removal, waterproof, damping, shock proof and oxidation proof.
