backup onto the upper shoulder of stem. Lubricate seal and ball
surface with o-ring grease.
3. Lubricate the top of the upper shoulder of stem with Jet
Lube and slip the thrust washer onto the stem.
4. Lubricate the top of the thrust washer and packing gland
threads with Jet Lube and slip the packing gland onto the stem.
5. With the stem at to the left, screw the packing gland/stem
assembly into the body center opening until the opening of the

to 150 in. lb. (17 Nm) in 25 in. lb. (2.8 Nm) alternating incre-
ments.
11. Back seat glands off on both sides and retorque to 75 in. lb.
(8.5 Nm) in 25 in. lb. (2.8 Nm) alternating increments.
12. While holding seat glands secure with a wrench, tighten

Precautions
Hold the seat glands with a wrench when tightening or
loosening the tubing connections.
DO NOT OPERATE THE VALVE WITH
MORE THAN 75 IN. LBS (8.5 Nm)

Ball valves can trap pressurized media inside the valve.
Relieve this pressure by turning the handle to the “half-
open” position before disassembling the valve.
Section 4.0
Maintenance

4.1.2 While holding the seat glands and the body
secure, loosen the tubing connections
4.1.3 With the handle in the “Full Open ” position,
gradually tighten the glands alternating from one gland to
