DRINKING WATER WAFER BUTTERFLY VALVE EPDM SEAT
VAMEIN, KTN, FERGO
Range: DN50 – DN1200
Pressure: PN16 / 10
Maximum temperature: -40ºC / 180ºC
Drinking water wafer butterfly valves: The butterfly valve was specially designed for drinking water applications. The body is made of GGG40 (EN AK210W GJS 400-15) with an epoxy paint finish, the disc is made of stainless steel 1.4408 (CF8M), the sealing collar is made of EPDM.
The butterfly valve is DVGW drinking water certified. All butterfly valves can be easily automated to the standardized (EN ISO 5211) mounting flange.
Approval DVGW drinking water with pneumatic quarter-turn actuator single acting, electric quarter-turn actuator J4C-S85, running time (90°): 29s ± 10%, multi voltage 24V – 230V – 240V AC/DC and DVGW drinking water with gearbox
