Principle Features

 
  • Diaphragm technology is better in high traffic, poor water conditions and high back pressure.
  • Equilibrated Diaphragm seat ensures stable outlet pressure even with sudden and varying inlet pressure changes.
  • Maximum Flow rate with Minimum Fluctuation in reduced pressure.
  • Stainless steel spring is not in contact with the potable water, hence the spring remains corrosion free.
  • In-built strainer prevents dirt particles from reaching internals of the valve to avoid valve failures.
  • Reinforced Canvas Rubber Diaphragm gives strength and longer life.
  • Internal moving parts are made of high quality plastic with SS304 insert for longer smoother life and also prevents water hammer.
  • 'Cartridge' design internals -entire working mechanism is in a cartridge which operates independent of the body. Thus servicing is without removing body from pipe work.
  • Valve is provided with provision for inserting pressure gauge on the outlet sides.
  • The outlet pressure can be adjusted by turning the adjustment nut.
