Operating Procedure - SPX FLOW Power Team A Operating Instructions

NOTE:
• This valve has a low-torque design for use with
either single-acting or double-acting cylinders.
• Move the valve handle to any position by
loosening the cap screw and rotating the stem
in increments of 22 1/2° to the position desired.
Torque the cap screw 60/80 in. lbs. See Figure 1.
1. Remove the port plugs from the pump, valve and
cylinder.
2. Apply a high quality, nonhardening pipe thread
sealant or PTFE tape to the external threads of all
hydraulic connections. IMPORTANT: Use only one
layer of PTFE tape. Apply tape carefully, two
threads back, to prevent it from being pinched
by the fitting and broken off inside the pipe end.
Any loose pieces of tape could travel through
the system and obstruct the flow of oil or cause
jamming of precision-fit parts.
3. Connect the stressing hose from the stressing jack
to the "A" port of the valve. See Figure 2.
4. Connect the return hose of the stressing jack to the
"B" port of the valve. NOTE: Always connect the
return line to port "B".
5. Attach the tool to the tensioning cable.
6. Shift th valve to port "A". The jack will tension the
cable.
7. To hold cable tension, shift the valve to the center
position.
8. Shift the valve to return port "B". The cable tension
will be held while the wedge ram extends and builds
pressure. The pilot-operated check valve will open
when the correct pressure ratio has been reached,
allowing the stressing jack to return.
WARNING:
For use on PE30 Series pumps
replace the mounting screws with longer mounting
screws (No. 10856). See Figure 2.
