what are the common material of the cock valves?

Cock valves may not be well known to the general public, but they are used in many of our piping systems.The plug body with through hole is used as the valve of the opening and closing part, and the plug body rotates with the stem to realize the opening and closing action.Plug valve is the earliest use of a valve, simple structure, quick switch, fluid resistance is small.There are many materials of plug valve in our market.

Stainless steel cock valve

The stainless steel plug valve is made of stainless steel.It can be divided into four types according to the structure: compact type plug valve, self-sealing type plug valve, packing type plug valve and oil-filling type plug valve.According to the channel form, can be divided into two drum plug valve, three-way plug valve and four-way plug valve three.Its simple structure, relatively small size, light weight, easy to maintain.Low fluid resistance and tightness

Cast steel cock valve

Cast steel plug valve is a closed piece or plunger type rotary valve, by rotating 90 degrees so that the valve plug on the channel mouth and the valve body on the channel mouth interlinked or separate, to open or close a valve.It is most suitable to be used as cutting and switching medium and shunt, but it can also be used for throttling depending on the nature of use and erosion resistance of sealing surface.Plug valve is widely used in oil field exploitation, transportation and refining equipment, but also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, hvac industry and general industry.

All copper cock valve

All copper cock valves may be cylindrical or conical in shape.In a cylindrical plug, the channel is generally rectangular;In a cone plug, the channel is trapezoidal.These shapes make the structure of the plug valve lightweight.It is most suitable for cutting and switching media and shunt application, but it can also be used for throttling depending on the applicable nature and the erosion resistance of the sealing surface.And copper is also a very good metal performance, corrosion resistance is also very strong.
