Wafer Butterfly Valve
Wafer Butterfly Valve stands as the most dependable industrial solution which fulfills all your requirements. The valve operates with a cartridge seat design and streamlined disc and robust stem-to-disc connection to deliver top performance in various industrial sectors including food and beverage and pulp and paper and chemical and mining and water treatment and power plants.
The valve features ISO5211 top flange and stem square mounting for direct actuator attachment and stem anti-blowout protection for safe operation in the field. The valve includes a dirtscraper which blocks moisture from entering the shaft area while its multiple standard alignment holes support different flange standards including EN1092 PN10 and PN16 and ASME B16.5 CLASS150 and JIS B2239 10K 16K and BS 10 table D & E. The cartridge seat design enables the valve to operate under high pressure conditions and complete vacuum conditions.
The Wafer Concentric Butterfly Valve includes a cartridge-style seat and streamlined disc and robust stem-to-disc connection which makes it suitable for various industrial uses including food and beverage and pulp and paper and chemical and mining and water treatment and power plant operations.
