Description
Pre-engineered Process Control Valves to Meet Various Process Conditions
We are providing high performance control valves for industries such as oil and gas, petrochemicals, food, chemcial and water treatment to maintain safety, reliability, and performance.
It has a compact structure, opening and closing flexible, strong corrosion resistance, short stroke (generally 1/4 nominal diameter) and other advantages. It is widely used in petroleum, chemical and other pipeline systems to do cut off the medium, but need to emphasise that the fluoroplastic lined globe valve is strictly prohibited to be used as a flow control, so as not to throttle the mouth of the high-speed media flow erosion damage to the sealing surface.
The valve stem is designed as a one-piece structure to prevent the fluctuations caused by the possibility of internal parts flushed out of the valve body, reliable and safe to use.
Structural features: B.B or W.B, sealing surface using alloy steel or hard alloy, sealing material pair reasonable, long service life, valve flap is conical, the valve stem is equipped with inverted sealing
The surface of the valve stem by nitriding treatment, it has a good resistance to corrosion, friction resistance, packing using flexible graphite.
The sealing is reliable, flexible, open and close with small torque, it can be used in a variety of piping standards and connections.
Various piping standards and connection forms are available (e.g. socket welding, butt welding, threaded connection).
In the fluid system, the control valves are widely used to control the direction of the fluid, pressure, flow of the device.
Valves can be used to control the flow of various types of fluids such as air, water, steam, a variety of corrosive media, mud, oil, liquid metals and radioactive media.
Valve is an significant control components in pipeline and equipment fluid delivery system , it is used to change the access section and the direction of media flow, with infusion, cut-off, throttling, check, shunt or overflow pressure relief and other functions.
