G114/G115 Series Bellows Control Valve

The bellows control valve is a pressure-balanced control valve with compact body structure, S streamlined fluid passage, low-pressure drop loss, large flow rate and wide adjustable range.

Bellows control valve due to the deformability of the bellows element itself and outstanding aging resistance, this bellows control valve control valve completely overcomes the weaknesses of packing aging and temperature sensitivity that usually exist in packing seal valves. Secondly, the double sealing structure of bellows and packing is adopted, which has better safety and reliability. Therefore, bellows control valve is widely used in automatic control systems for rare and special media such as highly toxic, highly corrosive, and radioactive media.
