» Precision double “D” disc to stem connection drives the disc without the need of screws or pins
» Bray’s bonded seat design lowers torque and provides complete isolation of flowing media from the body
» The stem is retained in the body by means of a unique Stainless Steel
» Non-corrosive, heavy duty acetal bushing absorbs actuator side thrusts
» Double “U” cup seal design is self-adjusting, gives positive sealing in both directions, and prevents external substances from entering the stem bore
» Extended neck length allows for 2″ of piping insulation and is easily accessible for mounting actuators
» These seals prevent line media from coming in contact with the stem or body
» Spherically machined and hand polished to provide a bubble-tight shutoff, minimum torque, and longer seat life
