![]() ![]() Maintenance of the valve is quick and relatively simple. This eliminates excessive wear between the seat and disc-sealing interface both during the opening and closing strokes extending the sealing life of the valve. The valve has a double offset design providing a camming action. This prevents excessive disc deflections, which maintains a constant disc/seal contact stress ensuring a bi-directional sealing valve at both low and high pressures. This single piece construction also provides a rigid assembly when pinned to the disc via means of shaft pins (peened over and locked). ![]() If failure of the shaft -to -disc connection, or internal failure of the shaft occurs due to excessive torque, no portion of the shaft can be ejected from the valve as result of internal pressure. ![]() The shaft is of one piece construction with an anti-blowout feature on the non-drive side and a reduced diameter at the actuator end. Geometry: Double offset giving low unseating and seating torques electroless nickel plated spherical blade periphery is an option.Body styles: Double Flanged, Wafer Lugged, Wafer Flangeless.Fire safe and non-Fire safe: Certified Fire safe to BS 6755 part 2 and BS EN ISO 10497. ![]()
