Bellow Sealed valve manufacturer in USA:

Valvesonly is a leading Bellow Sealed valve manufacturer in USA. The structure of a Bellow Sealed valve is used to balance the pressure. The Valve is constructed with bellows rather than stuffing boxes unlike other valves. Bellow sealed valves prevent leakage of medium to the atmosphere and are commonly used in pipelines with zero leakage. Because the valve is entirely closed, the seal prevents leaking. This valve is designed for pipelines that carry steam, flammable, explosive, or hazardous media. This sort of valve does not require a flow rate that is fully open or fully closed. Even if the bellows are broken, this valve may resist leaking due to valve system packing because of its structure.

A Bellow Sealed Valve, also known as a “Zero Leak Valve” or a “Emission Free Valve,” is an industrial process valve that is designed to eliminate valve leakage. A metallic Bellow Cartridge attached to the valve bonnet at one end and the stem at the other end adds to/supplies the traditional gland packing in these valves. A bellow is a long tube that looks like an accordion. The bellow expands or contracts in response to the valve stem’s stroke action. The process fluid cannot pass through any sliding or rotating seals. The fluid will enter the valve through the seat of the valve and make contact with the bellow, but not with the stem.

Types of Bellow Sealed Valve:

  • Bellow Sealed Gate Valve.
  • Bellow Sealed Globe Valve.

Bellow Sealed Globe Valve:

A Bellow Sealed Globe valve has a compact structure which is used to balance the pressure. It adopts the structure with bellows instead of stuffing boxes like all other valves. The seal prevents leakage from the valve as it is completely locked. The bellow sealed Globe Valve is suitable for pipelines where steam, flammable, explosive and hazardous media passes through. It does not require fully opened or closed flow rate. Due to this structure, this valve can avoid leakage due to packing of the valve system even if the bellows are broken.

Bellow Sealed Gate Valve:

A Bellow Sealed Gate valve has a compact structure which is used to balance the pressure. It adopts the structure with bellows instead of stuffing boxes like all other valves. The seal prevents leakage from the valve as it is completely locked. The bellow sealed Gate Valve is suitable for pipelines where steam, flammable, explosive and hazardous media passes through. It does not require fully opened or closed flow rate. Due to this structure, this valve can avoid leakage due to packing of the valve system even if the bellows are broken.
