Torque arm. To reduce wear on packing rings, to
enable better sealing and to reduce torque.
Impactor handwheels. 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 handwheel. Two lugs cast under the wheel
strike simultaneous blows and give 3–10 times the
closing force of standard handwheels. Impactor
handwheels are supplied at manufacturer’s option
unless specified by customer (see page 21).
Flanges. Class 150–300: 1⁄16" raised face. Class 600:
1⁄4" raised face. Finish 125 –250 AARH for all valves.
