The LoPro™ Valve has a smaller profile, is lighter, lower in cost, and easier to maintain than similar competitive valves. With its small footprint, this valve fits easily into existing systems and saves space on new system designs. The LoPro Valve lifetime can extend to 1,000,000 cycles under clean conditions, greatly increasing system uptime. A formed stainless steel bellows prevents outgassing, virtual leaks, and particle entrapment between bellows convolutions and extends the LoPro Valves’ life cycle. The bellows’ stroke length is optimized to assure a longer cycle life while maintaining a high conductance.
Another standard feature is a one-piece machined aluminum body made of high grade, corrosion resistant, 6061-T6 Aluminum for significantly fewer entrapment areas, resulting in less contaminant build-up. In the event of power or air loss, the pneumatic LoPro Valve will automatically spring to close. Actuation can be pneumatic or manual.
The LoPro Valve is available in both angle and inline versions. Port sizes include outside diameters of 1, 1½, and 2 inches and standard port interfaces include KF flanges. For leak-tight operation, elastomer seals are available in Viton® for typical vacuum operating conditions, and in Kalrez® or Chemraz® for higher temperature conditions and increased chemical resistance.
