Pressure relief safety valves for power washing from brands such as General Pump, Giant, Fluid Controls & more. Options from 1/4 to 1/2 in & 1200-6000 psi.

1) Position the pop-off valve on the discharge side of the pumping unit between the pump and the unloader. The 1/4" MNPT or 3/8" MNPT is the inlet. (Mount unit directly onto the pump for best results.) 2) Adjust the valve relief pressure setting as follows: a. Start the pump with the shut-off gun open and adjust the system pressure to 600 PSI

7. Remove the guided p-valve, (19), valve springs (18), v-sleeves (21) and pressure rings (20). Inspect for wear and replace as necessary. Remove the spacer ring (17) from the plungers (8). 8. If the crankcase oil seals (15) are to be replaced, they can be removed by prying loose with a screwdriver. Take care not to make contact with the

The Automatic Thermal Relief Valve is a must for any system utilizing a closed loop bypass line or internal bypass. The valve is designed to protect your pump and accessories against

safety and pressure setting. • Fixed chemical injector is standard and mounts directly onto unloader to provide cleaning flexibility. *Gas Mounting Flange: SAE J609, Flange B, Extension 4 (1"Ø), Shaft Length= 3 1/4", Pilot Ø= 5 3/4", BC.

pressure loss to the work area. It is essential to provide a safety bypass valve between the pump and the work area to protect the pump from pres-sure spikes in the event of a blockage or the use of a shut-off gun. Finally, remember that high pressure operation in a pump system has many advantages. But, if

l Press-in seal cases and interchangeable valve assemblies for easy servicing. All High Pressure Systems require a primary pressure regulating device (i.e. regulator, unloader) and a secondar y pressure relief device (i.e. pop-off valve, relief valve). Failure to install such relief devices could result in personal injury or damage to pump or

Valve Replacement: All inlet and discharge valves can be serviced without disrupting the inlet or discharge plumbing. The inlet and discharge valves are identical in all 66 TSF series models. To service the valve assemblies: 1) Remove valve cap. Remove valve plug using 2, 4 mm x .7 mm threaded bolts. 2) Remove outlet valve assembly from plug.

• Integral Pressure Unloader with built-in by-pass standard on all units to assure system pressure control and pump protection. • Fixed chemical injector standard on all units offers cleaning flexibility.

Finally, remember that high pressure operation in a pump system has many advantages. But, if it is used carelessly and without regard to its potential hazard, it can cause serious injury.
