The NUTORK double offset butterfly valve is a high performance valve that offers superior service life and is trouble-free to maintain. The second offset in the design of promotes effortless operation by virtually eliminating disc-on-seat friction during seating and unseating. The disc lifts quickly out of the seat in the first few degrees of travel, and does not make contact with the seat again until it is nearly closed, reducing seat wear and the overall operating torque of the valve. The integrally cast disc travel stop perfectly locates the disc and seat, preventing over-travel and consequent seat damage. This design promotes the self-
alignment of the disc and seat, and therefore compensates for change in pressures and temperatures always ensuring of the disc and seat, and therefore compensates for change in pressures and temperatures always ensuring bi-directional bubble tight shutoff. Its double offset design minimize the wears points at the top and bottom seat. It has performed 100,000 mechanical cycle type testing and meet with zero leakage with high pressure air.
