Wafer/Lug 1-12Ԕ (25mm-300mm) SERIES 20/21 ACTUATOR MOUNTING FLANGE AND STEM CONNECTION 1-12Ԕ (25mm-300mm) BRAYS UNIQUE SEAT DESIGN Bray Controls offers a new line of butterfly valves with two-piece 316 Stainless Steel bodies in wafer style and lug style. 1Ҕ-1ݔ valves are wafer bodies 2-12Ԕ valves are wafer and lug bodies 1-6Ԕ valves are investment cast bodies 8-12Ԕ valves are sand cast bodies This special line of valves has the specific advantage of a high integrity corrosion resistant exterior for use in aggressive environments. is one of the valves key elements. The resilient seat features a unique ғtonque and groove retention method which holds securely between either slip-on or weld-neck flanges and also allows simple and fast field replacement. This resilient seat features lower torque than many valves on the market today and provides complete isolation of flowing media from the body. Designed for direct mounting of Bray power actuators and manual operators. This design meets ISO 5211. Extended neck allows easy access without interference with pipe flanges. No brackets or adapters are required. DISC/STEM An important feature is the one-piece design. This design provides outstanding protection from the particle entrapment and bacterial growth. The thin disc profile allows a high flow capacity (Cv rating, up to 50% greater than most through-stem designs) and greater pressure recovery thus resulting in lower pressure drops and a more energy efficient valve. Disc/stems are offered as investment cast 316 Stainless Steel or fabricated 316 Stainless Steel. PRIMARY AND SECONDARY SEALS The Primary Seal is achieved by an interference fit of the molded seat flat with the disc hub. The Secondary Seal is an interference fit as a result of the stem diamter. These seals prevent line media from coming in contact with the stem or body. FLANGE LOCATING HOLES Provide quick and proper alignment during installation, thus allowing the installer to center the valve in the pipeline between the flanges. > 316 STAINLESS STEEL VALVE FOR FOOD, BEVERAGE & CHEMICAL INDUSTRIES BUTTERFLY VALVES
