Series 200 High Performance Butterfly Valve
The INCOLOK® Series 200 double offset butterfly valve is a high performance valve that offers superior service life and is troublefree to maintain. Its reliable sealing performance and wide range of working conditions is the result of the technologically advanced double offset seat design. The second offset in the design of the Series 200 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 on to the seat, preventing over-travel and consequent seat damage. This design promotes the self alignment of the disc and seat, and therefore compensates for changes in pressure and temperature always ensuring bi-directional bubble tight shutoff.
