Plunger valve

Short Description:

1. The sealing pair of plunger valve is composed of a stainless steel plunger, two elastic sealing rings and a metal support ring which can keep the fixed distance between the upper and lower sealing rings. The plunger, like a cork, is inserted in two sealing rings. Valve body and seal ring, plunger and seal
2. Wear resistance when closing the plunger valve, the valve rod drives the plunger to insert into the sealing ring, just like plugging the bottle plug into the bottle mouth. No matter how much force is exerted
3. It is convenient to disassemble and maintain. There is a certain clearance between the valve body and the valve cover of the plunger valve. Once the sealing ring is worn, it will match with the plunger
4. It is easy to open and close, and the operation is flexible. The sealing ring material selected for the plunger valve has small thermal expansion coefficient, good self lubrication, high strength and friction

Plunger valve is a kind of valve which can be opened or closed by rotating 90 degrees to connect or separate the channel port on the valve plug with that on the valve body.

Its plunger can be cylindrical or conical in shape. In the cylindrical plug, the channel is generally rectangular, while in the conical plug, the channel is trapezoidal. These plug shapes make the valves light. It is most suitable for use as a cut-off and make-up medium and as a shunt, but can sometimes be used for throttling depending on the nature of the application and the erosion resistance of the sealing surface.

1. The plunger valve is used for regular operation, which can be opened and closed quickly and conveniently.
2. The fluid resistance of the plug valve is small.
3. The plunger valve has the advantages of simple structure, small volume, light weight and easy maintenance.
4. Good sealing performance.
5. Without the limitation of installation direction, the flow direction of medium can be arbitrary.
6. No vibration and low noise.
