Product Description
Wafer Type Double Eccentric High Performance Butterfly Valve
The double offset design assures reduced seat wear and bidirectional, zero leakage shut off throughout the full pressure range.
At the initial point of disc opening, the offset disc produces a cam-like action, pulling the disc from the seat. This cam-like action reduces seat wear and eliminates seat deformation when the disc is in the open position. When open, the disc does not contact the seat, therefore seat service life is extended and operating torques are reduced. As the valve closes, the cam-like action converts the rotary motion of the disc to a linear type motion to effectively push the disc onto the seat.
The wiping action of the disc against the seat prevents undesirable material build-up from slurries or suspended solids.
