Taco 3350-T2 Bronze Cartridge Style Pressure Reducing Valve, 1/2", NPT, 10 - 50 psi
  • Automatically feed water to a hydronic system whenever pressure in the system drops below the pressure setting of the valve
  • 1-handed fast-fill lever speeds system filling time
  • Water media
  • Stainless steel and engineered plastics internal parts
  • 12 psi factory setting and 230 psi maximum inlet pressure Taco self-compensating cartridge style pressure reducing valve, sets a new standard for performance and serviceability. All the parts are contained in a 1-piece cartridge which can be easily removed and serviced without reducing the system pressure. A fast-fill mode that automatically returns to the normal mode when the set pressure is reached and delivers increased flow to speed system fill times. Its unique dial-in pressure setting allows for easy adjustment throughout the 10 - 50 psi range, without the need for an external gauge. Quality features include a stainless steel spindle, integral stainless steel coaxial strainer and easy, dial-up pressure setting that eliminates pressure gauges. The cartridge style design ensures unsurpassed output pressure stability. A balance between diaphragm position and spring tension based on the desired outlet pressure is consistently maintained, even when inlet pressures fluctuate severely. The unique 1-piece cartridge design significantly reduces diaphragm load, extending the overall product life. Unlike conventional PRV designs, the diaphragm does not double as a seal between the body and the cap. This allows for optimization of the diaphragm for its intended use - maintaining pressure stability. A unique encapsulated shaft seal system prevents flowing media from contacting the diaphragm, greatly extending diaphragm life. If the diaphragm ever does fail, the encapsulated shaft and body seals work together to stop water from exiting the valve. Use of a stainless steel coaxial strainer prohibits system debris from affecting the valves performance. An integral check valve allows the cartridge to be removed under system pressure for replacement or servicing.,
