Product Description
- The stem is retained in the body by means of a unique stainless steel Spirolox® retaining ring, a thrust washer and two C-rings, manufactured from brass as standard, stainless steel upon request
- The retaining ring may be easily removed with a standard hand tool
- The stem retaining assembly prevents unintentional removal of the stem during field service
- Non-corrosive, heavy duty acetyl bushing absorbs actuator side thrust
- Double "U" cup seal design is self-adjusting and gives positive sealing in both directions
- Extended neck length allows for 2 in of piping insulation and is easily accessible for mounting actuators
- Casting is spherically machined and hand polished to provide a bubble-tight shut-off, minimum torque and longer seat life
- These seals prevent line media from coming in contact with the stem or body
- Primary seal is achieved by an interference fit of the molded seat flat with the disc hub
- Secondary seal is created because the stem diameter is greater than the diameter of the seat stem hole
