Bellows seal valves

Bellows Seal Valves for Corrosive Applications

Microfinish bellows seal valves include a formed bellows welded to the stem on one side and to the bottom of the bonnet at its bottom end, creating a tight seal. Bellows are available in many materials for most corrosive chemical applications.

In applications where total containment of toxic media is mandatory, Microfinish bellows seal globe valves excel. Our valves carry a maintenance-free guarantee of 5,000 cycles, and a higher cycle life of 10,000 cycles is available on request.

The valve line is offered in stainless steel 316L as the basic material configuration; however for severe service and corrosive applications, exotic materials like duplex, super duplex, Hastalloy-C22 and Titanium are also available.

Microfinish bellows seal globe valves have been reliably in service in nuclear, power and chemical plants for more than 20 years.They are especially effective in chemical plants handling fluids which require zero leakage to the atmosphere and maximum site safety.
