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.
