WAFER BODY BUTTERFLY VALVES (ACTUATOR VALVE)

BUTTERFLY VALVES WITH ACTUATOR Wafer butterfly valves with epoxy coated ductile iron body are designed to control various media in commercial and industrial applications. The valve is mounted between two standard ANSI/ASME Class 125/150 and other international flanges. It eliminates the need for a flange gasket seated on the flange gasket. The disc is precision machined 316SS. Two-piece body and disc design increases flow capacity and reduces turbulence. Features ISO5211 top mounting for manual, air or electric actuators Unique soft seat reduces torque and extends seal life Epoxy coated ductile iron body 316SS disc with 2-piece body design increases flow capacity EPDM, NBR (Buna-N), FPM or VMQ sealing options PTFE graphite reinforced body bearings Pressurized 230 PSI (16 Bar) Multi-standard flanged mounting holes Optional 10-position locking lever Applications Wafer body butterfly valves are used to control the flow of water, oil, air, vacuum and other media compatible with building materials. Valves can be operated by manual, air or electric actuators. Four gasket options available: EPDM, NBR (Buna-N), FPM, VMQ Temperature range EPDM Gaskets: -20 to 120ºC Buna-N Gaskets: -15 to 85ºC FKM: -15 to 200ºC VMQ: -30 to 200ºC Operation Direct mount wafer butterfly valves can be easily installed with an optional manual operator, air actuator or electric actuator using the standard ISO5211 top mount. Turning the square shaft a quarter turn moves the stainless steel disc and opens or closes the valve. The unique soft seat reduces the torque required to close the valve and extends seal life.
