APPLICATIONThe Fulflo “V” Series range in size from 3/8”through 2” and operate efficiently with liquids ofany viscosity at pressures from 2 to 1000 P.S.I.The “V” series valves are available in flange orscrew type...cartridge or handwheel in a choiceof brass, cast iron, steel and stainless steel.

Widely used in a variety of applications, the “V”series valves are ideally suited in hydraulic andlubricating systems for load regulation andsystem protection. Special trim or packings areavailable for use with fire resisting fluids andother liquids of this type. Unusual applicationsand special requirements should be referred toour engineering staff for recommendation.

INSTALLATIONFulflo valves can be mounted in any position. Atee may be inserted in the pump discharge lineto mount the valve. The correct size of valveshould be installed, preferably matching thepump discharge line. Screw the valve into thenipple in the tee, or in the case of the flangestyle, bolt the valve to the companion flangescrewed into the nipple. When the valve is usedfor frequent bypassing of oil pressure, its outlet

should be piped back to the tank. Care must betaken to have the discharge well below the oillevel in the tank to prevent air entrainment anderratic operation.

Only if the valve is used as safety or overloadrelief and operates infrequently may itsdischarge be piped back into the pump suctionline. Frequent or continuous operation underthese conditions will cause excessive heating ofthe oil and possible damage.

SETTING VALVESValves may be set with a hydraulic hand pump forcracking pressure. If a test stand is available, valveshould be connected to the discharge header with thepump bypass open, and the bypass gradually closeduntil the desired pressure registers on the gauge.Adjust valve adjusting screw until valve slightly bleedsat the set bypass pressure and lock adjusting screw.

Fulflo valves are not designed to be positive shut-off,and will pass a minimal amount of leakage before theset pressure. If a valve is required to bypass a givenamount of fluid at a given pressure, a test stand

TYPICAL DISASSEMBLY OF STANDARD TYPE VALVE

having a flow meter in the pump discharge line mustbe available. With a valve adjusted for crackingpressure as above, continue closing bypass until therequired flow registers on the flow meter and observepressure. Readjust pressure, if necessary, to obtaindesired pressure at desired flow.

MAINTENANCEFulflo valves provide reliable “chatter-free” operationwhen the system is free of abrasives and foreignmatter. Continuous filtration of the liquid used isstrongly recommended.

To dismantle valve for inspection or cleaning:1. Remove cap “B”2. Remove O-Ring “E”3. Remove lock nut “F”4. Remove adjusting screw “C”5. Remove retainer “D”6. Remove spring “G”7. Remove piston “I”8. Remove stop ring “H” (Not Recommended)

(Special tooling is required to install new stop ring.)

Inspect valve bore and piston for wear and scoring.Replace broken or damaged parts. Clean all partsthoroughly and re-assemble by reversing the aboveprocedure.

TYPICAL DISASSEMBLY OF HANDWHEEL TYPE VALVE

To dismantle the valve for inspection or cleaning:1. Release spring tension by backing off handwheel as far as it

will go.2. Remove lock nut “A” or set screw and take off handwheel “B”3. Remove lock nut “D”4. Unscrew and remove gland “E”5. Unscrew and remove bonnet “F”6. Remove O-Ring “H”7. Remove adjusting screw “C” (turn clockwise and pull out from

bottom of bonnet “F”)8. Remove O-ring packing “G”9. Remove spring “J”

10. Remove piston “K”11. Remove stop ring “L” (Not Recommended)(Special tooling is required to install new stop ring.)

Inspect valve bore and piston for wear or scoring. Replace brokenor damaged parts. Clean all parts thoroughly and re-assemble byreversing the above procedure.
