Lockout kit installation instructions for F952 DN 250 - 600 knife gate valves

To install on existing valves

1. Ensure pipeline is not pressurized and that
any hazardous medium is drained away.

2. Fully close valve. Remove clevis fasteners
and actuate cylinder or handwheel so clevis
lifts clear of gate.

3. Remove glandbox fasteners, then lift
glandbox off gate.

4. Remove all glandbox studs. Care should be
taken to avoid damage to the gate.

5. Ensure threaded glandbox stud holes are
clean, then install extended length studs
using Loctite provided.

6. Loop the free end of the lockout pin
connecting wire over each stud on one
side of the valve.

7. Check the condition of the packing.
Replace if necessary (separate instructions
available).

8. Reinstall the glandbox and fasteners. An
anti-seize compound should be used on the
nuts. Do not over tighten the fasteners.

9. Install the lockout bosses on the studs using
Loctite, and screw down until the bottom of
the hole is in line with the top of the gate.
Ensure the holes in the bosses on opposite
sides of the gate are aligned.

10. Insert the pins to verify installation. The gap
between the top of the gate and the bottom
of the pins should be kept to a minimum.

11. After pipe is pressurized, adjust gland as
necessary.
