U41SM- 16 c cast steel flange plunger pneumatic valve DN25

unsharp mask plunger pneumatic valve synopsis: plunger pneumatic valve by pneumatic valve, pneumatic valve cover, pneumatic valve stem, plunger, the hole planes, ring, hand wheel, etc. Parts ( As shown in figure) 。 When the hand wheel rotation, through the pneumatic valve rod drives the plunger in the middle of the hole rack up and down reciprocating movement to complete the pneumatic valves open and close function.
in the pneumatic valve USES the interference fit between plunger and seal ring, by adjusting the gland flange bolts, make the seal ring compression side force of the products and pneumatic valve hole in the side column and the Great Wall round seal, so as to ensure the sealing of the pneumatic valve, put an end to the inner leakage, pneumatic valve small open torque, at the same time to achieve rapid opening and closing of the pneumatic valve.
because of the sealing ring with strong resilience, high wear-resistant nontoxic new sealing material, have suffered long-term high temperature, high pressure without losing elasticity, so the sealing performance, reliable and durable.
flange plunger pneumatic valve installation and maintenance: plunger pneumatic valve when using just the appearance and hole cavity clean, don't have to unpick and wash and replacement.
the piston pneumatic valve can be installed in any position, see a pneumatic valve body medium flow direction indicated by the arrows.
after a period of use of sealing ring if there are any wear and leakage must first will pneumatic valve is turned off, then in the flange bolts evenly slightly tighten even when no leakage can be replaced at the same time, should prevent the plunger and the new seal ring cracks and bruised.
in a short period of time, heating and temperature difference between the larger pipeline, plunger pneumatic valve cannot be used.
