Taco 329-3 Cast Iron Boiler Feed Pressure Reducing Valve, 1/2", Sweat Taco boiler feed valves automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve. The dual control models combine the boiler feed with an in-line pressure relief valve. The built-in check prevents emptying the system if incoming pressure falls. They feature fast fill rates and an exclusive, lockable fast fill lever. Taco boiler feed valves have set the standards for dependable service. Each valve is adjustable from 10 - 25 psi, has a built-in check to prevent the emptying of the system if incoming pressure fails, and the easy to use fast fill lever is lockable.Sid Harvey Item #:329-3: Replaces Part #:'s : L41-607,

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.,

Taco air scoop's special design and internal baffles of Taco air scoops slow water velocity to separate the air from solution. Thanks to this design, Taco air scoops efficiently remove air to provide noiseless, air-free hydronic heating, cooling or combination systems. They also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank.
,
- 1-piece cast iron construction
- Never requires any servicing
- Engineered baffle separates air from water
- Each air scoop has a vent connection on top for the installation of a 1/8" Taco 400-3 or 416-1 Hy-Vent and 1/2" bottom tapping for a diaphragm expansion tank
- The 1-1/2 - 4" air scoops also have an additional top tapping for the connection of a plain steel expansion tank
- Water or water/glycol media
