Cat Pumps Accessory: 7076 / 7350 Pressure Regulator w/Handle   Leave a comment


Cat Pumps Accessory: 7076 / 7350 Pressure Regulator w/Handle


7076 / 7350 CAT Pressure Regulator w/Handle (1.0-12 GPM, 800-1500 PSI) 271, 277, 311, 317

SELECTION
This pressure regulator is designed for systems with single or multiple pumps, solenoid (gate) valves, nozzles, standard or “weep” guns.
Note: For multiple pump systems, it is best to use a pressure regulator not a pressure sensitive regulating unloader.
This regulator should meet both the desired system flow (combined nozzle flow rate requirement) and the desired system pressure.

NOTICE: Operation below the minimum flow of the regulator causes the regulator to cycle or chatter. Operation above the maximum flows of the regulator causes premature regulator wear, regulator cycling and prevents attaining desired system pressure.

INSTALLATION
This regulator operates properly when mounted in any direction; however, it is preferred to keep the plumbing to
a minimum and the adjusting cap easily accessible. The
best mounting location is directly on the pump discharge manifold head or in discharge line using a “T” fitting. Flexible, high pressure hose (minimum single wire braid) should be at least the size of the regulator ports when plumbing to and from the regulator.
The inlet connection is located on the side and is a 1/4” NPTF sized port. Plumb into this port for discharge flow from
the pump.
The by-pass connection is located on the bottom and is a 3/8” NPTF sized port. By-pass fluid is directed out of this port and can be routed to a reservoir or to a drain.

OPERATION
This pressure regulator maintains established system pressure in the discharge line and at the pump head when the trigger gun is closed, solenoid (gate) valve is closed or the nozzles are clogged, thus by-passing all unrequired flow. Squeezing the trigger gun or opening the solenoid (gate) valve allows for a quick return to established system pressure.

PRESSURE ADJUSTMENT
1. Setting and adjusting the regulator pressure must be done with the system “on”.
2. Start the system with regulator backed off to the lowest pressure setting (counterclockwise direction).
3. Squeeze the trigger and read the pressure on the gauge at the pump.
Note: Do not read the pressure at the gun or nozzle.
4. If more pressure is desired, release the trigger, turn adjusting cap one quarter turn in clockwise direction.
5. Squeeze the trigger and read the pressure.
6. Repeat this process until desired system pressure is attained.
7. Once the desired system pressure is reached, stop turning the adjusting cap and thread jam nut down towards upper body of regulator to lock in place.

NOTICE: A minimum by-pass flow of 5% of the regulator rated flow is required for proper regulator performance. If the entire output is directed through the nozzles (zero by-pass) the “cushioning” feature of the by-pass liquid is eliminated and the regulator can malfunction or wear prematurely.

8. If desired system pressure cannot be reached, review TROUBLESHOOTING chart.
9. When servicing existing systems, back off jam nut.
10. Follow adjustment procedures as stated above for new regulators.

Note: Do not adjust regulators pressure setting to compensate for a worn nozzle. Check the nozzle as part of the regular maintenance and replace if worn.
Note: A secondary pressure safety relief device (i.e., pop-off valve, safety valve) should be used along with this pressure regulator. Final adjustment for the relief valve should relieve at 200 psi above the system operating pressure.

Disassembly:
1. Disconnect by-pass and inlet plumbing from regulator.
2. Remove regulator from pump.
3. Secure lower body of regulator in a vise with adjusting handle facing upwards.
4. Remove adjusting cap and unthreading from upper body in a counterclockwise direction.
5. Remove upper body by unthreading from lower body.
6. Remove upper spring retainer, spring set and conical piston.
NOTICE: Exercise extreme caution to avoid contact and damage to outside diameter and sharp tip of conical piston.
7. Remove lower body from vise and place on flat surface with by-pass port facing upwards.
8. Using a tool with the same diameter as that of the conical seat drive out the conical seat and piston retainer.
NOTICE: Exercise extreme caution to avoid contact and damage to the inside diameter of the piston retainer as well as the outside diameter and tapered surfaces of the conical seat.
Note: With the regulator completely disassembled, inspect sealing area where the conical seat and piston retainer makes contact within the lower body of the regulator for grooves, pitting and wear. If damage is found, stop the repair and replace with new lower body or complete new regulator. If not, proceed with reassembly.

Reassembly:
1. Place lower regulator body with by-pass port facing downwards in a vise.
2. Lubricate and install o-ring onto outside diameter of conical seat. Press conical seat down into lower regulator body with tapered surface facing upwards.
3. Lubricate and install o-ring onto piston retainer. Press piston retainer with larger diameter facing downwards.
4. Place conical piston on a flat surface with sharp point facing upwards. Lubricate and install backup-ring, then o-ring onto outside diameter of conical piston. Lubricate outside diameter of conical piston.
5. Press conical piston with sharp point down into piston retainer.
6. Place upper body with large opening facing up.
7. Drop spring retainer into cap, ensuring spring pilot faces up.
8. Drop in 28 spring washers, alternating direction per exploded view on the last page.
Note: A small rod such as an ink pen can be used to guide the washers into the cap to ensure proper orientation is maintained.
9. Invert lower body assembly onto upper body and thread together.
10. Thread adjusting cap into upper body
11. Re-install regulator onto pump.
12. Reconnect by-pass and inlet plumbing to regulator.
13. Proceed to PRESSURE ADJUSTMENT.
