BUTTERFLY VALVE

  • BUTTERFLY VALVES, CONTROL VALVES

    Our standard Batley Valve® BV 22000 Hyperseal can be drilled to suit international standards up to class 300lb and special valves can be manufactured with bodies drilled to suit flanges up to ANSI class 2500lb. The seat is designed to move slightly in the flow direction, this allows the pressure access to the back of the seat, thus making the seal progressively tighter as the pressure increases. Any slight deflection on the disc in the case of very high pressures, increases the tightness and shut of potential. 90° on/off action allows for fast operation and the low torque characteristics are an economic advantage in power operation.

  • TRIPLE OFFSET BUTTERFLY VALVES

    Tricentric® Metal Seated Valves perform favourably when compared to conventional resilient seated and high performance butterfly valves over all services ranges. Tricentric® Triple Offset Valves incorporate 3-way eccentricity. The metal seat is capable of a very tight seal at temperatures up to 1,500°F.
