GMK ANSI Standard Bellows Seal Gate Valve

One variety of gate valves is the GMK ANSI Standard bellows-sealed gate valve. To regulate the flow of fluid through a pipeline, gate valves feature an opening and closing gate. Rising from a handwheel at the end of a long bellow is the stem of the Bellows Sealed Valves. The majority of the bonnet bolt is made up of a hefty hex, making it simple to service. The flange can be finished off with a weld, a socket weld, or a National Pipe Thread connection. These specialized valves have many different uses, such as in fire-safe and zero-emission builds, as well as in secondary seals that produce fewer emissions, in welded bonnet designs, and in seats and wedges. Welding the bellows to the stem and the underside of the bonnet creates an impenetrable barrier. In contexts where alternative materials are utilized to make these valves, the Bellows seal cast steel valves are extremely prevalent. Valves can be found produced from a variety of materials, including austenitic steel, carbon steel, duplex steel, and other alloys. Stainless Steel Bellows Seal Valves come in a range of sizes and grades to suit a wide variety of needs. The valve gland or stuffing box may leak over prolonged use, however, the system as a whole is leakproof. The valve and pipeline need to be serviced regularly to control this.

  • The seal bellow: The bellow is the most important component of a bellow-sealed globe valve. Roll welding is the automatic joining of the cover to the stem. Because of the mental bellow, the root is safe from any seepage.
  • Two-way protection (bellows and packaging). The combination of a bellow and packing can provide a very effective seal.
  • The stem, nut, and sleeve can all be directly lubricated.
  • Comfortably shaped hand wheel is more convenient to use and has a longer lifespan.


  • Bellow seal element. The mental bellow can keep the stem part no leakage
  • Double seal design. Bellow and packing can protect against leakage and provide an excellent seal
  • Grease nipple. It can direct lubricate the stem, nut, and sleeve
  • Ergonomic handwheel. It provides longer service life and easier operation
  • Application: Hot oil system, steam system, hot and cold water system, etc
  • Suitable temperature: -196 degree C to 600 degree C
