The VH is to be used when higher o/p pressures (above 5 bar) are needed which the standard W3 cannot support (though the range of VH is 1.5 to 10 bar). This need arises mostly in hydropneumatic type systems and where PRVs have to be installed in basement only ( and not in ducts outside apartments) for reasons like ease of access; limited space in duct; or inaccessible ducts .


Pressure Reducing Valves protect household water installations for industrial or commercial applications within the range of their specification. By installing a pressure reducing valve, pressurisation damage is avoided and water consumption is reduced. The set pressure is also maintained constant even when there is wide inlet pressure fluctuation. Reduction of the operating pressure and maintaining it at a constant level minimizes flow noise in the installation. The VL is specialy designed for lower outlet pressure without compromising on the flow rate. These are especially used when more then 4 branches are drawn from one downtake line and the last branch tends to get very high pressure in spite of using a PRV.

  • Built-in filter to prevent dirt particles from reaching internals thus avoiding static pressure failures.
  • Since the prv is Diaphragm operated it has better pressure control ,less noise and maintenance compared to the older piston operated PRVs.
  • Moreover, Diaphragm is thin walled , corrugation shaped for better flexibility & smoother operation. Increased surface area of diaphragm reduces overall size of PRV. i.e. compactness.
  • Nylon reinforced NBR Diaphragm for better strength and longer life.
  • Transparent filter cap which shows dirt accumulated on filter. (currently in 40 & 50 mm size only)
  • Easy clean attachment (optional) helps flush out all dirt particles collected on filter at mere turn of a knob. No need to open the valve for cleaning. No downtime. No technician.
  • Moving parts are of low weight engineering plastic (with metal insert) to ensure quick response time to changes in inlet pressure or flow conditions thus reducing noise levels significantly and give smoother pressure control.
  • ‘Cartridge’ design internals - entire working mechanism is in a cartridge which operates independent of the body. Thus, servicing is without removing body from pipeline.
  • The valve cartridge is of high quality synthetic material and can be fully exchanged.
  • ‘Dual open’ design. Filter can be opened and cleaned from other side without disturbing pressure settings or removing working mechanism (cartridge).
  • In-built provision for inserting pressure gauge.
  • Inlet pressure balancing - Fluctuating inlet pressure does not influence outlet pressure.
  • Light weight.
  • Stainless steel spring & spring plate and powder coated Gun Metal / Bronze body (optional) for rust free, corrosion free, dezincification free valve for longer life.

*OPTIONAL Easy Clean feature in VH-SC variant.
Has built in filter of SS304 with Standard 200 micron filter and with easy cleaning attachment.
