Lever/Pressure Operated Control Head, P/N 82-878751-000

The Lever/Pressure Operated Control Head allows manual or pressure actuation of several
system components, including HFC-227ea cylinder valves and nitrogen actuators (see
Figure 3-18).
SAFETY PIN
4.50 in.
(114.3 mm)
Before resetting the lever/pressure operated control head, all pressure must be
relieved from the cylinder and actuation lines.
Pressure can be relieved from unvented actuation tubing by loosening the
fitting on the control head slightly and allowing the line to bleed out completely.
Failure to perform this action can result in damage to the control head.
WARNING
When attaching the Lever/Pressure operated control head to the valve, the
swivel nut must be tightened to a toque of 55ft·lb. Failure to tighten the swivel
nut may result in leakage during actuation.
