THE VAMEIN 100 SERIES WAFER TYPE BUTTERFLY VALVE
We manufacture WAFER TYPE valves from DN-50 mm (2") to DN-1200 mm (48") in standard execution and from DN-1200 mm. (48”) to DN-2000 mm. (80”) as special production.
Assembly between flanges: Multiflange system from DN-50 (2") to DN-300 (12") allowing the assembly between PN-6, PN-10, PN-16, ANSI-125/150 Lbs and B.S. 10-D/E flanges, with only one model.
From DN-350 (14") flanges are assembled according to PN-10, PN-16, ANSI-125/150 Lbs. BS, AWWA, and any other standard on request.
Standard working pressure: 16 Bar (DN 50-300) and 10 bar (DN 350-1200). For higher working pressures, ask our Technical Department.
Temperature limits: –40ºC to +180ºC (depending on liners and coatings).
Our design includes four centring holes to allow a perfect alignment and quick fitting between flanges, up to DN-500 mm (20"). From DN-600 mm (24") and abore, we include tapped holes on both sides of the body as well as the four centring holes.
As this is a pattern to be fitted between flanges, the mechanical stress of the pipe is transmitted to the valve only by compression on the body and there is no mechanical tension stress which might create watertightness problems. (It is necessary to take into consideration that DN-600 mm - 24" bodies and larger have four tapped holes on bothsides.
