Globe Valve

DIN Bellow Seal Globe Valve

DIN bellow seal globe valve that its opening and closing is plug valve, sealing surface appears flat or cone, disc make linear movement along the center-line of fluid. Stem form of exercise, there is lifting lever (valve rod, the hand wheel (not lifting), there are also lift rotating lever (hand wheel rotating lifting with the valve stem and nut in the body). Globe valve is used for full open and closed,but not to adjust the flux. DIN Bellows Seal Globe Valve is a new kind of globe valves with dual-seal. So its sealing is very good. The sealing surface is bead welding with hard alloy and the stem surface is in"nitrogen treatment". Hence it is the valve of attrition-resistant, good anti-corrosion performance and long service life.

Advantage:

  1. Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage.
  2. Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.
  3. Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
  4. Grease nipple. It can direct lubricate the stem, nut and sleeve.
  5. Ergonomic hand wheel. It provide longer service life and easier operation.
