ductile iron disc check valve, tilting disc check valve
Tilting Disc Check/butterfly Valve, GGG40/DUCTILE iron, CASTING, WITH HAMMER, BS5155/EN/DIN/ASME
Standard:BS5155 OR EQUIVALENT
Nominal diameter: DN300-DN1000mm
Tilting Seat Buffering Check Valve of the sealing surface is declined against the outlet with small dropping angle to reduce the
vibration meanwhile there is buffering device in the body which can buffer by the flow to prevent the pump from turning back and
super-high water hammer pressure.

Product description:
Tilting disc check valve, ductile iron disc check valve with hammer
Features
Non slamming closure
Smooth and noiseless sealing
Low head loss, low cost operation.
Blow out proof design
Rugged construction
Extended hinge shaft and counterweights on both sides of the valve
Precision machined titling disc and seat for tight shut-off in reverse flow direction
Corrosion resistant inner parts ensure long term service under adverse conditions
All parts, including the seat, are easily field replaceable, thus minimizing down time
Designed with off center pivot to avoid the tendency of the disc to slam on the seat and to aid the operation at low pressure differentials
Application:
It is suitable for all kinds of pipelines with nominal pressure PN1.0MPa~42.0MPa and Class150-2500, nominal diameter DN15~1200mm
and NPS1/2~48, and at working temperature 196~540 C. It is used to prevent backflow of media. Through the selection of different materials, it can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and many other medias.
