Butterfly valves WAFER J9 double-acting pneumatic actuator

J9 is a concentric butterfly valve with WAFER connection, designed for shut-off and regulation in pipe systems for water and other media. The valve is built in ductile iron with a disc in AISI 316 and an EPDM seal; NBR seals and other materials in the disc and body are available on request. The pneumatic actuator version is available in double-acting and single-acting versions in sizes DN40 to DN300 for PN10/16, and the same valve body can also be operated with a lever, gearbox, or electric actuator at 230 V or 24 V DC. The integrated ISO flange to ISO5211 makes mounting and changing the actuator easy, and the face-to-face length follows EN558/1-20, giving dimensionally accurate fit between flanges. The working temperature is -10 to +120 °C.
