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 with integral press fitting ends, a tight seating check valve, stainless steel strainer, and purge lever for manual purging. 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 air gap for reduced pressure zone assembly, 1/2 IN series 009, 3/4 IN series 009M2 and 009M3, and 1/2 to1 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).

Compression x SS-T20 BSP Fittings are available for a range of applications, including connecting RadiantPEX/RadiantPERT to Stainless Steel Manifolds or to 3/4 in. male BSP x male sweat fittings. SS-T20 Compression Fitting models are also used to connect RadiantPEX-AL to stainless steel and T20 manifolds. SS-T20 Compression Coupling Kits (non-BSP) join lengths of RadiantPEX/RadiantPERT.

This 3 inch lead free reduced pressure zone backflow preventer assembly prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards. This assembly consists of an epoxy coated cast iron body, domestic outside stem and yoke resilient seated gate valves, captured spring check valves, replaceable seats, top mounted test cocks, and a field reversible pressure differential relief valve. The coating on this backflow assembly uses ArmorTek technology to resist corrosion due to microbial induced corrosion (MIC) or exposed metal substrate. This backflow assembly contains an integrated flood sensor with SentryPlus™ Alert technology to detect excessive water discharges from the relief valve. When activated through an add-on sensor connection kit, the flood sensor relays a signal that triggers notification of potential flooding to service personnel. The add-on sensor connection kit is available for building management systems and cellular communication.

This valve actuator is desiged for low wattage, individual radiant circuit control. It provides on/off flow control to individual radiant circuits. Incorporates an indicator window that allows a visual indicator whether the valve is fully open or closed. Flow can be balanced prior to installing by turning the adjustment valve under the blue cap. Actuator is 24 VAC (1.6 W) with four wires to connect to the thermostat and close an end switch.

This 5/8 inch x 1200 foot coil of RadiantPEX+ (TM) is used for radiant heating, snow melting, supply and return piping. It is an integral ethylene vinyl alcohol din standard O2 barrier that limits oxygen diffusion through the wall of the tubing. It has a protective polypropylene layer to the outside of the EVOH oxygen barrier. It is rated maximum temperature 200 degrees F and maximum pressure rating 160 psi.
