8. Maintenance Notes
Anytime that the valve is serviced, the pressure drop
across the primary stage must be verified and can be reset
by adjusting the Top Cap on the first Pressure Stage.
Refer to Appendix A & C for component details.
1. With valve at no inlet pressure:
−
Install a 15,000 PSI gauges into Inlet and first
pressure stage test port (adjacent to inlet)
using 3/8" Autoclave fittings.
−
Remove the Top Cap Lock Screw on the first
Pressure Stage.
−
Tighten the Top Cap, then back it out if
necessary until a node lines up with the Lock
Screw hole.
2. Apply flow to the inlet at 7,000 -10,000 PSI.
3. Read the pressure differential between the 2
gauges. If the differential is less than 2500 PSI:
−
Stop the flow to the valve, allowing all
pressure to drain.
− Back out the Top Cap ONE node ONLY.
! CAUTION
NEVER OPEN THE TOP CAP MORE THAN 4 NODES FROM
TIGHTENED POSITION AND NEVER UNDER PRESSURE.
4. Repeat the flow test and readjust until the
differential is 2,500-3,500 PSI.
5. Replace the Top Cap Lock Screw and torque to 10-
foot pounds.
! CAUTION
WATCH THE WEEP HOLE IN THE SIDE OF THE BODY
ADJACENT TO THE TOP CAP MOUNTING HOLES. IF FLUID
IS DETECTED, SHUT DOWN POWER IMMEDIATELY. THE
TOP CAP COULD BE OPEN TOO FAR OR THE SEAL IS
DAMAGED.
Replacing Seals: When replacing valve seals, it is
recommended that the new seals be lubricated with Parker
Super Lube or equivalent. Install backup ring on low
pressure side of O-ring. For more details, see seal kits
sheets (2) in Appendix C, D or E. Make sure the backup
ring is lined up at the joint.

NOTE : Loctite #271 requires heat (such as a propane
torch) to disassemble.

9. Storage
When storing SkoFlo valves prior to first use, it is
recommended that the valves be stored indoors. If stored
outdoors, apply a light coating of protectant to the
exterior of the valve. The shipping plugs in the HP INLET,
RELIEF, and VENT should remain in place.
When storing SkoFlo valves after being in use, dismantle,
clean thoroughly and reassemble. Then store as noted
above.
