Design Features: The seat is made of a highly wear resistant elastomer with a phenolic backup ring on the 2–14" sizes and aluminum on sizes 16–36". This combination provides a soft, elastic seat which will not collapse under vacuum or high velocity service and eliminates the need for flange gaskets. The stem seals consist of a primary seal between the spherical disc hub and the spherical seat hub. The secondary seal is an O-ring at the top of the stem to retain lubrication and prevent atmospheric corrosion. The stem is blowoff proof. Lugged style valves are rated for bi-directional dead end service to the full pressure rating of the valve.
These valves can be furnished in a variety of trim materials. Ten position handles are available for manual operation as well as a gear operator with handwheel. Pneumatic or electric actuators with solenoids, positioners and limit switches can be specified for automated operation.
ISO mounting and double D shaft on 2” through 36”.
