Cam-Tite Bellows Stem Seal
Cam-Tite Ball Valves are also available with a bellows stem seal. This stem seal device, manufactured by Kerotest Manufacturing Corp., provides a hermetic stem seal via a unique quarter-turn bellows design.
The interface design for the bellows stem seal to the Cam-Tite Ball Valve was a joint effort between Engineered Valves and Kerotest in which the bellows assembly becomes integral to the bonnet of the valve. This allows for disassembly should replacement of internal components be required. The device can also be easily actuated. Bellows stem seals are available in ANSI Class 150 and 300 in a variety of materials.
