Offers straight-through, unimpeded flow. The wiping action of the Teflon across the ball reduces particulate buildup, making this valve robust in particulate rich effluent streams.

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

Ball valve has less wetted surface than poppet valve. 

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.

Heater jacket is available to reduce by-product condensation.
