Small Electric Valve With High Efficiency And Energy-saving Advantages To Occupy The Market
Jul 20, 2017

The valve is the control part of the fluid conveying system, which has the functions of cut-off, regulation, diversion, preventing countercurrent, voltage stabilizing, shunt or overflow discharge. Valves for fluid control systems, ranging from the simplest valve to a very complex control system, have a wide range of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metals and radioactive media. Valve and pipe connection mode is an important parameter, according to this classification are:
1, threaded connection: the valve body with internal thread or external thread, and pipe thread connection.
2, flange connection: valve body with flange, and pipe flange connection.

3, welding connection: The valve body with welding groove, and pipe welding connection.
4. Clamp connection: The valve body is provided with a clamp, which is connected with the pipe clamp.
5, the card sleeve connection: With the pipeline uses the card sleeve connection.
6, to clamp connection: with the bolt directly to the valve and two pipes in the form of the connection.

Valve Body Material:
1, metal Materials: valve body and other parts made of metal. such as cast iron, carbon steel, alloy steel, copper alloy, aluminum alloy, lead alloy, titanium alloy, Monel alloy and so on.

2, non-metallic Material: valve body and other parts made of nonmetal materials. such as plastics, ceramics, enamel, FRP and so on.
3. Metal lining: The valve body shape is metal, the internal contact with the medium of the main surface are lined, such as lining, plastic lining, ceramic lining.
