General Description

George Fischer offers three differentpressure regulating valve designs thateither reduce, retain or relieve pressure.These valves provide highly accurateand stable pressure control irrespectiveof fluctuations of inlet pressure orchanges in flow demand.

The valve body works by balancing anadjustable spring force, that pushesdownward onto a diaphragm, againstthe force of the process fluid pushingupward. The valve is adjusted by anadjusting screw and secured with alocknut. The mechanic parts of the valveare isolated from the process fluid.

George Fischer pressure regulatingvalves can handle a wide range of flowand pressure control applications.

As in all George Fischer productofferings, the safety, reliability, durabilityand quality of the finished product areof paramount importance. In addition toquality products that meet localstandards, we always strive to provide ahigh standard of service and technicalsupport.

General

The Type V782 Pressure Reducing Valve(PRD) reduces pressure to a given value.Utilizing the differential pressure thevalve adjusts itself to the set workingpressure and maintains it on thedownstream side irrespective offluctuations of inlet pressure or changesin flow demand. The valve works bybalancing an adjustable spring force,that pushes downward onto adiaphragm, against the force, of theprocess fluid pushing upward. The valveis adjusted by a set screw and securedwith a locknut.


• Dimension range3/8" – 1-1/2"

(16 mm – 50 mm)



• NPT, spigot, socketunion, or flangedend connections

General

The Type V86 Pressure Retaining Valve

(PRT) is installed to maintain constantback pressure in the line upstream ofitself. An increase in pressure upstreamwill cause the valve to open, therebymaintaining the set constant backpressure. The valve works by balancingan adjustable spring force, that pushesdownward onto a diaphragm, againstthe force of the process fluid pushingupward. The valve is adjusted by a setscrew and secured with a locknut.

General

The Type V786 Pressure Retaining Valve(PRT) is installed to maintain constantpressure in the line upstream of itself. Anincrease in pressure upstream will causethe valve to open, thereby maintainingthe set constant pressure. The valveworks by balancing an adjustable springforce, that pushes downward onto adiaphragm, against the force of theprocess fluid pushing upward. The valveis adjusted by a set screw and securedwith a locknut.

General

The Type V85 Pressure Relief Valve (PRL)may be used in all pipelines where nogreater pressure than the set linepressure is desired. The valve operateswhen the set line pressure is exceededby 10%. The lift being proportional to theincrease in pressure. The excess liquid isdischarged through the branch. Thevalve works by balancing an adjustablespring force, that pushes downward ontoa diaphragm, against the force of theprocess fluid pushing upward. The valveis adjusted by a set screw and securedwith a locknut.
