BioviZion fractional-size valve line includes EnviZion valve platform in a compact package for 0.25 to 0.5” applications. Features include a mechanical thermal compensation system whereby a sealing force is constantly applied to prevent external leaking over a range of temperature changes. A quick change bonnet eases valve maintenance, and high strength stainless steel studs eliminate the need for small fasteners that are prone to galling, breaking and misplacement. The patented design of the diaphragm stud simplifies diaphragm installation. Assembled with a simple mount-and-turn motion, the valve is maintained in approximately 3 min without using any special tools or difficult torquing procedures. The valve’s 360° active seal protection provides leak-free operation, helping eliminate the risk of contamination and the need to re-torque after thermal cycling.
