Piston valve is a new product developed on the basis of extensive research and summary of stop valve and plunger valve. This new piston valve has many advantages: first, it adopts doubleSeal, (first metal to metal axial seal, then flexible seal ring to stainless steel valve seat radial seal) so the sealing performance is particularly good. Second, it has a long service life due to its pistonThe ring (flexible seal ring) is installed on the piston, so it is not directly eroded by the medium. Third, the flow of medium through the piston valve is large and the flow resistance is small. Fourth, the opening and closing stroke is short, occupying spaceSmall, more conducive to indoor or narrow space. Fifth, the maintenance is very convenient. If the valve leaks after long-term use, just turn the hand wheel a little more when it is closed, It can produce axial force, and the flexible seal ring will expand radially under the action of axial pressure, so the original sealing performance can be restored. If it is convenient to replace the sealing ring, take out the piston and replace it Piston ring.
It is widely used in the pipe network of water, gas and hot oil, steam and viscous medium ≤ 250 ℃. (if you need to use temperature ≤ 390 ℃ or ≤ 550 ℃, you can customize high-temperature sealing ring).
