Watts Water 9DM2 Forged Brass Dual Check Backflow Preventer with Intermediate Atmospheric Vent, 3/4", Female Union

It prevent the reverse flow of hot or cold polluted water from entering into the potable water supply
• It consists of a brass body with stainless steel internal parts, integral strainer, and two durable, tight-sealing, rubber check valves
• For continuous pressure, non-health hazard applications in smaller supply lines
• It features a primary check valve utilizing a rubber disc seating against a mating rubber part to ensure tight closing
• A secondary check valve utilizes a rubber disc-to-metal seating
• In the event of fouling of the downstream check valve, leakage would be vented to atmosphere through the vent port thereby safeguarding the potable water system
• True line-sized construction allows the check modules to open further allowing dirt and debris to pass more freely reducing check fouling
• Maximum flow at low pressure drop
• Furnished with union connections to facilitate removal and replacement for maintenance
• Compact for economy combined with performance
• Design simplicity for easy maintenance
• Can be installed vertically or horizontally

Watts Regulators series 174A boiler pressure relief valves are used in hot water heating and domestic supply boiler applications to protect against excessive pressures on all types of hot water heating supply boiler equipment. It consists of a bronze body construction with NPT threaded female inlet and NPT threaded female outlet (drain) connections, non-metallic disc-to-metal seating, stainless steel spring, and test lever. Series 174A resists corrosive water conditions, 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.

Safety relief valves for pressure protection only of all types of hot water heating boiler equipment
• 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
• Water seal of high temperature resisting material isolates spring working parts from water during relief

Maid-O-Mist The number 7 series Auto-Vents are reliable, automatic air eliminating valves for concealed radiators, pipe lines, tanks and other devices where water or liquids are used for heating and cooling. They have proven to be the solution to problems that have confronted engineers and contractors in which air pockets or traps retard the free circulation of the liquids and reduce the efficiency of the system or appliance. The numer 7 series Auto-Vents air eliminators are made of brass and equipped with a self-closing, float-operated valve. The valve is equipped with a monel metal spring and a neoprene valve seat which is unaffected by high temperatures, oil and anti-freeze. No air chamber is required. The vent is regularly fitted with a patented cap that may be used as a check in case of a leak caused by core sand or scale.

Combination connection
• They vent air continuously and help your system work at peak efficiency
