FV2000 SERIES VALVE FV-SERIES VALVES

Transcription

1 V00 SS VLV The ulflo V00 Series valve is similar to the V-Series valve, includes a new safer design that protects liquid and gasses from venting out of the valve during normal operation and adjustment conditions. This valve has been especially designed to prevent the adjusting screw from backing out while making adjustments to the pressure setting. n o-ring has been incorporated around the adjusting screw to further prevent liquid from escaping. PPLTON The ulflo V Series range in size from through and operate efficiently with liquids of any viscosity at pressures from to 0 P.S.. The V series valves are available in flange or screw type... in a choice of brass, cast iron, steel and stainless steel. Widely used in a variety of applications, the V series valves are ideally suited in hydraulic and lubricating systems for load regulation and system protection. Special trim or packings are available for use with fire resisting fluids and other liquids of this type. Unusual applications and special requirements should be referred to our engineering staff for recommendation. NSTLLTON ulflo valves can be mounted in any position. tee may be inserted in the pump discharge line to mount the valve. The correct size of valve should be installed, preferably matching the pump discharge line. Screw the valve into the nipple in the tee, or in the case of the flange style, bolt the valve to the companion flange screwed into the nipple. When the valve is used for frequent bypassing of oil pressure, its outlet should be piped back to the tank. are must be taken to have the discharge well below the oil level in the tank to prevent air entrainment and erratic operation. Only if the valve is used as safety or overload relief and operates infrequently may its discharge be piped back into the pump suction line. requent or continuous operation under these conditions will cause excessive heating of the oil and possible damage.

2 STTN s may be set with a hydraulic hand pump for cracking pressure. f a test stand is available, valve should be connected to the discharge header with the pump bypass open, and the bypass gradually closed until the desired pressure registers on the gauge. djust valve adjusting screw until valve slightly bleeds at the set bypass pressure and lock adjusting screw. ulflo valves are not designed to be positive shut-off, and will pass a minimal amount of leakage before the set pressure. f a valve is required to bypass a given amount of fluid at a given pressure, a test stand having a flow meter in the pump discharge line must be available. With a valve adjusted for cracking pressure as above, continue closing bypass until the required flow registers on the flow meter and observe pressure. eadjust pressure, if necessary, to obtain desired pressure at desired flow. MNTNN ulflo valves provide reliable chatter-free operation when the system is free of abrasives and foreign matter. ontinuous filtration of the liquid used is strongly recommended. TYPL SSSMLY O STN TYP VLV To dismantle valve for inspection cleaning: 1. emove cap. emove O-ing. emove lock nut. emove adjusting screw. emove bonnet 6. emove spring. emove piston 8. emove stop ring (Not ecommended) (Special tooling is required to install new stop ring.) nspect valve bore and piston for wear and scoring. eplace broken or damaged parts. lean all parts thoroughly and re-assemble by reversing the above procedure. No Leaking, ripping, Spills or Venting The ulflo V00 Series valve includes a new safer design that prevents liquid and gasses from venting out of the valve during normal operation and adjustment conditions. This valve has been especially designed to prevent the adjusting screw from backing out while making adjustments to the pressure setting. n o-ring has been incorporated around the adjusting screw to further prevent liquid from escaping. Operates fficiently and ffectively The V00 Series valves can be mounted in any position with sizes ranging from through, and will operate efficiently with any application or viscosity at pressures from to 0 psi. lange or screw connections are available in brass, cast iron, steel or stainless steel. ll parts are completely interchangeable and convertible with other ulflo V- Series valves. ulflo dvantages These valves offer ulflo s patented chatter-free performance and are ideally suited for hydraulic and lubricating system protection. ll ulflo valves include a patented modulating piston design with absolute or differential pressure operation. Our advanced modulating operation allows ulflo valves to be used in many different applications including positive displacement or centrifugal pump and system protection. ulflo valves can be mounted in any position. 1
