CAUTION
To avoid damage to the tangential pins, disk pins, valve disk, or shaft(s) resulting from the application of excessive force,
use appropriate care when driving the pins into the disk hub and shaft(s). Use the right tool. Do not use excessive force.
12. Install the appropriate tangential pins, and disk pins. Use 2 tangential pins that will go through the upper shaft
and 1 disk pin that will go through the lower shaft.
13. Refer to the Anti‐Blowout Design, Packing, Valve Shaft, Disk and Bearing Maintenance procedures in this manual
to re‐install the packing and anti‐blowout design.
Gasket Retainer
Valves with a two‐piece shaft use a gasket retainer and gasket (keys 20 and 21) to cover the lower shaft opening in the
valve body. The gasket is held in place by the gasket retainer and four hex head bolts and lockwashers (keys 23
and 22). When re‐assembling the valve, use a new gasket.
Be sure to center the gasket over the lower shaft bore before retightening bolts. Tighten down bolts evenly in a
crossover or star pattern.
Refer to table 6 for proper torque values.
