Pneumatic Globe Valves Introduction： 

Pneumatic valve opening and closing pieces of plug-shaped flap, the sealing surface was flat or tapered surface, the valve flap along the center line of the fluid for linear motion. Stem movement form, lifting rod (stem lift, hand wheel does not lift, there are lifting rotary rod (hand wheel with the stem rotating together, the nut is located in the valve body). Globe valve only applies to fully open and fully closed, does not allow for regulation and throttling.

Pneumatic Globe Valves Advantage：

1 , Selection of sophisticated, in line with domestic and foreign standards, reasonable structure, handsome in appearance.

2 , the valve disc, seat sealing surface using iron-based alloy surfacing or Sellite ( Sellite ) cobalt-based hardfacing from welding, wear-resistant, high temperature, corrosion resistance, good scratch resistance, long life .

3, the stem by quenching and nitriding surface treatment, good corrosion resistance and scratch resistance.

4, Can adopt all kinds of pipe flange standard and flange sealing surface type, to meet various engineering needs and user requirements.

5, the full range of valve materials, packing, gaskets can be reasonable according to the actual conditions or user requirements matching, can be applied to a variety of pressure, temperature and media conditions.

6, inverted seal using threaded seal seat or body made of welded austenitic stainless steel, sealed, replace the filler can be carried out without downtime, convenient and does not affect the system operation.
