Stainless Steel Pneumatic Ball Valve

Application

Ball Valve is ideal for isolating reactor, trap and scrubber on vacuum coating tool for harsh and corrosive environment.

Down-stream of chemical reaction chamber is challenged by by-product deposition and particulate. 

Wiping action of the Teflon across the ball reduces particulate buildup, making this valve robust in particulate rich effluent streams.

Body, stem, ball and end caps are made of 316L stainless steel. Fluoroelastomers are used to seal the stem from atmosphere.  PTFE (Teflon) seals around the ball to isolate processes.  Blow-out proof stem, full bore with internal surface of Ra < 0.4 give the valve extended life.

 

Features
Vacuum rating of 1x10-8 torr
Bakeable to 150oC (200oC intermittent)
Manufactured from 316L stainless steel
Particulate resistant ball/seat design lengthens mean time to repair
High conductance; straight through flow
Service valve without removal from the system
"Fail Safe" air-to-open, spring-to-close available
80-120 psig operating air pressure
Available connection : Weld Tube, KF, ISO

Stainless Steel Manual Ball Valve

Application

Offers straight-through, unimpeded flow, wiping action of the teflon across the ball reduces particulate buildup;  typical of dirty environment

Ball valves are commenly used on MOCVD and CVD equipment down stream from chamber (for process control) or vacuum pump (for abatement control)

Ball valve has less wetted surface than poppet valve.   1/4 turn handle is easy to use

Heater jacket is available to reduce by-product condensation.
