I-795/906 / Installation-Ready ™ Knife Gate Valve / Installation and Maintenance Instructions
3a. CLOSE VALVE: For handwheel operated valves, operate the
handwheel slowly in the “closed” direction (clockwise) to bring the
seat toward the valve body . Ensure that the tab of the seat is facing the
slot in the valve body, as shown in step 1 . To prevent damage to the
surfaces of the seat, do not attempt to operate the handwheel at an
increased rate, or by using a drill or impact gun .
3b. For pneumatically and hydraulically operated valves, actuate the
valve closed to bring the seat toward the valve body .
WARNING
• Keep hands away from the edges of the knife
seat while replacing it into the valve body.
• Keep hands away from the seat cartridge and
yoke while actuating the valve.
Failure to follow this instruction could result in
personal injury.
4. REPLACE RETAINING BOLTS: When the retaining plate is
1 inch/25 mm or less from the valve body, insert the four hex cap bolts
and flat washers through the retaining plate and into the valve body, as
shown above .
5. TIGHTEN RETAINING BOLTS: Tighten the four hex cap bolts evenly
by alternating sides (as shown in the sequence above) until the lock
washers are fully compressed . There should be metal-to-metal contact
between the plate and the housing .
