- Universal trim: 13 Cr stem, wedge in CA 15 or 13 Cr faced and CoCr alloy faced seat API trim 8 suitable for applications up to 850 deg F (454 deg C)
- Seat face CoCr alloy hard faced, ground and lapped to a mirror finish
- Conical seat machined to fine surface finish
- Body guided disc accurately mates the hard faced surface of the disc (hard faced with 13 Cr, CoCr alloy, SS 316 or Monel) with the surface of the body seat, which is ground and lapped to a mirror finish
- The disc guides are hard faced to extend the wear life of the disc guides
- Body and bonnet castings are precision machined
- One-piece bonnet for better alignment, fewer parts
- Stuffing box machined to fine surface finish
- Body and bonnet joint accurately machined to fine surface finish
- Fully enclosed gasket
- Gland has two-piece construction for easy alignment
- Rotating stem nut is austenitic ductile iron grade D-2C, renewable in-line
- Torque arm reduces wear on packing rings and enables better sealing and reduces torque
- Impactor hand wheels: globe and stop check valves require higher closing torques than gate valves with the same seat diameter and pressure class
- The most economical mechanism for tight shutoff is the impactor hand wheel
- Two lugs cast under the wheel strike simultaneous blows and give 3 to 10 times the closing force of standard hand wheels
- Impactor hand wheels are supplied at manufacturer's option unless specified by customer
