Product Details

Product Overview
The surface of the plunger of the cast steel plunger stop valve is processed by a high-precision cylindrical grinder, and the sealing ring is made of a non-toxic new sealing material with strong elasticity and high wear resistance, so the sealing is reliable and durable, thereby improving the service life of the plunger valve. The flange plunger valve can be processed according to American standards, Japanese standards, national standards, etc. It is installed on the steam pipeline, with no leakage at the valve stem, making it an ideal valve for boiler steam. No fluid loss improves energy efficiency and production equipment safety, reduces maintenance costs and frequent maintenance, reduces operating costs, and provides a clean and safe working environment.

Product Features
1. When opening and closing the plunger valve, the plunger moves slowly in the sealing ring, and the contact surface is almost not worn.
2. The sealing ring adopts a non-toxic new sealing material with strong elasticity and high wear resistance, so the sealing is reliable and durable.
3. The interference fit is used between the plunger and the sealing ring in the valve to ensure the sealing of the valve and prevent internal and external leakage.
4. When closed, the plunger is inserted into the lower sealing ring to cut off the flow passage; When opened, although the plunger detaches from the lower sealing ring, it is still hidden inside the upper sealing ring to maintain isolation from the outside and prevent leakage.
