Watts Regulators series 740 boiler pressure relief valves are used in hot water space heating boiler applications to protect against excessive pressure on all types of hot water space heating boiler equipment. It consists of a iron body construction with expanded outlet drain connections for hot water space heating boilers, non-metallic disc-to-metal seating, stainless steel spring, and test lever. Series 740 offers large discharge capacity, resists corrosive water conditions, resists sticking and freezing, and prevents water and sediment from being trapped in the seat. It is designed for emergency safety relief and shall not be used as an operating control.
- Iron body with expanded outlets for hot water space heating boilers
- Seat located above drain, water can't be trapped and sediment can't foul seat
- Non-mechanical seat-to-disc alignment will not stick or freeze
- Each hot water space heating boiler shall be equipped with a pressure relief valve set to relieve below the maximum boiler working pressure
- Water seal of high temperature resisting material isolates spring working parts from water during relief
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
