Description for Taco 3350-2

Taco's Cartridge Style Pressure Reducing Valve is used to automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve.
With its one-piece cartridge containing all the parts, you can easily remove and service the valve without reducing line pressure. A one-handed, fast-fill button delivers increased flow to speed system fill times, while its unique dial-in pressure setting allows you to make easy adjustments throughout the 10 - 50 PSI range without needing an external gauge.
Features Include:

  • One-Piece Cartridge--For fast serving and maintenance under pressure.
  • Self Compensating--Pressure balanced diaphragm ensures unmatched output pressure stability, even when inlet pressure fluctuates severely.
  • Stainless Steel Spindle+Reduces erosion and corrosion for premium performance over the life of the valve.
  • Integral Stainless Steel Coaxial Strainer+Prevents system debris from affecting valve performance.
  • Dial-Up Pressure Setting+Eliminates pressure gauges.
  • Quiet Operation, Easy Installation+In any position.
