Design Features:
1. card sleeve type soft sealing plug valve sealing is done by the sealing surface around the card sets, the unique 360 ° metal lip protection fixed card sets;
2. The valve has no cavity to accumulate the media;
3. The metal lip provides the self-cleaning function in the spinning process, which is suitable for the viscous and easily fouling conditions;
4. Two-way flow, it is more convenient to use installation;
5. The material and flange dimensions of the parts can be selected according to the actual working conditions or users’ requirements, and meet all kinds of engineering needs.
Newsway Valve company plug valve is a rotary valve with a closing piece or a plunger. By rotating 90 degrees, the channel port on the valve plug is communicated or separated with the channel port on the valve body to realize opening or closing.
Its valve plug can be cylindrical or conical. In cylindrical valve plugs, the channels are generally rectangular; in conical valve plugs, the channels are trapezoidal. These shapes make the structure of the plug valve lighter. It is most suitable as a cut-off and connection medium and shunt, but depending on the applicable properties and the erosion resistance of the sealing surface, it can sometimes be used for throttling.
The plug valves are classified according to the use: soft seal plug valves, oil lubricated hard seal plug valves, lift plug valves, three-way and four-way plug valves.
Soft-sealed plug valves are often used in harsh environments such as corrosive, highly toxic and high-hazardous media, where leakage is strictly prohibited, and where the valve material does not pollute the media. The valve body can be selected from carbon steel, alloy steel and stainless steel according to the working medium.
Lubricated hard seal plug valves can be divided into conventional oil lubricated plug valves and pressure balanced plug valves. Special grease is injected from the top of the plug body between the cone hole of the valve body and the plug body to form an oil film to reduce the opening and closing torque of the valve and improve the sealing performance and service life. The working pressure can reach 64MPa, the maximum working temperature can reach 325 degrees, and the maximum diameter can reach 600mm.
Lifting plug valves have various structural forms. When the valve is opened, the plug is raised, and the plug is rotated 90 degrees to the full opening of the valve to reduce the friction with the sealing surface of the valve body; when the valve is closed, the plug is rotated 90 degrees to the closed position. Drop to contact the sealing surface of the valve body to achieve sealing.
Three-way and four-way stopcocks are suitable for changing medium flow direction or for medium distribution. According to the requirements of the working conditions, you can choose soft sealing bushing or soft sealing, hard sealing lift plug valve.
