Working principle of threaded piston valve

The threaded piston valve is manufactured by precision cylindrical grinding machine on the surface of the piston. The sealing ring adopts a non-toxic new sealing material with strong elasticity and high wear resistance, so the sealing is reliable and durable. This improves the service life of the plunger valve.
Working principle of threaded piston valve
The closing of the threaded plunger valve is composed of a stainless steel plunger, two elastic sealing rings at the top and bottom, and a metal partition frame. The sealing effect is achieved by the tight fit between the plunger and the sealing ring. The plunger is inserted into the two sealing rings, and the sealing area is much larger than that of a normal globe valve; When opening and closing the plunger valve, the plunger slowly moves in the sealing ring, and the contact surface is almost not worn. When closing, the plunger is inserted into the lower sealing ring, cutting off the flow channel; When opened, although the plunger is detached from the lower sealing ring, it is still hidden inside the upper sealing ring, maintaining isolation from the outside world and preventing leakage.
