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
