This 3/4 inch dual check valve backflow preventer with atmospheric vent prevents the reverse flow of hot or cold polluted water from entering into the potable water supply. This valve is designed for continuous pressure non-health hazard applications in smaller supply lines, such as laboratory equipment, processing tanks, sterilizers, dairy equipment, and specifically for boiler feed lines. It consists of a brass body with stainless steel internal parts, integral strainer, two durable tight seating rubber check valves, and NPT female inlet and outlet connections.

This 3/4 inch bronze automatic reseating temperature and pressure relief valve with a 5 inch thermostat is installed directly in tank tapings and is used in commercial applications to provide automatic temperature and pressure protection for hot water supply tanks and hot water heaters. It features a bronze body with NPT male inlet and NPT female outlet connections, thermo-bonded coated thermostat, tamper resistant bonnet screws, automatic reseating feature, and test lever. The temperature relief is 210 degrees (99 degrees C) and the pressure relief is 150 psi.

This 1 inch stainless steel manifold with 2 circuits is made of heavy-walled stainless steel and designed for radiant heating and snow melting application with water or water/glycol solutions. Standard features include flow balancing valves and flow meters on each circuit. Manifolds are sold in pre-mounted pairs. The manifold has a maximum operating pressure of 87 psi at 167 degrees F.

This 3/4 inch boiler pressure relief valve is 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. It 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, not as an operating control. The pressure relief is set at 50 psi (344.7 kPa) with corresponding high pressure ratings up to 950,000 BTU/hr.

This 1/2 inch high capacity feed water pressure regulator is for use in commercial and residential hydronic heating systems to fill the boiler and piping system with water, and to maintain water pressure in the system at all times. It also provides make-up water to the system in the event of system leaks. It consists of a bronze body with union solder inlet and NPT threaded outlet connections, a tight seating check valve, purge lever for manual purging, and a stainless steel strainer. It has high capacity performance and a simplified servicing design. It is suitable for use in the boiler feed lines of hydronic heating systems. The maximum pressure is 100 psi (6.9 bar).

This 1 inch stainless steel manifold with 8 circuits is made of heavy-walled stainless steel and designed for radiant heating and snow melting application with water or water/glycol solutions. Standard features include flow balancing valves and flow meters on each circuit. Manifolds are sold in pre-mounted pairs. The manifold has a maximum operating pressure of 87 psi at 167 degrees F.

This 1 inch stainless steel manifold with 12 circuits is made of heavy-walled stainless steel and designed for radiant heating and snow melting application with water or water/glycol solutions. Standard features include flow balancing valves and flow meters on each circuit. Manifolds are sold in pre-mounted pairs. The manifold has a maximum operating pressure of 87 psi at 167 degrees F.

This air gap for reduced pressure zone assembly, 3/4 to 1 IN series 009 and 909, 1 to 1 1/2 IN series 009M2, and 1 1/4 to 2 IN series 995, provides an unobstructed, physical separation between the discharge end of a potable water supply line and an open receiving vessel. The installation of an air gap and drain line are recommended on reduced pressure zone assemblies. It can be installed vertically or horizontally (vent elbow required for vertical installation).

This 1/2 by 1/2 IN lead free dual check valve backflow preventer helps prevent the reverse flow of polluted water from entering into the drinking water supply at the service entrance or at individual outlets. This valve consists of a lead free brass body construction, with two plastic replaceable check valves and stainless steel springs. It is designed for non-health hazard residential water system containment, continuous pressure applications and is to be installed immediately downstream of the residential water meter, in a vertical or horizontal position. The minimum working pressure is 10 psi (69 kPa) and maximum working pressure is 175 psi (12 bar).
