This 1 1/4 inch boiler pressure relief valve is 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 an 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. It 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, not as an operating control. The pressure relief is set at 30 psi ( 206.8 kPa) with corresponding high pressure ratings up to 2,105,000 BTU/hr.

This 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 an iron and bronze body construction with NPT threaded inlet and outlet connections, a tight seating check valve, purge lever for manual purging, and a stainless steel strainer. This regulator has high capacity performance and simplified servicing design. It is suitable for use in the boiler feed lines of hydronic heating systems.

This 1 1/4 inch lead free reduced pressure zone backflow preventer assembly is designed to prevent the flow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as health hazards and for contaminants at the service line entrance. This assembly consists of a lead free bronze body, NPT end connections, quarter turn ball valve shutoffs with tee handles, top mounted test cocks, two in-line independent check valves, captured springs, and replaceable check seats with an internal relief valve for reduced space requirements.

This 1/2 inch 2-piece full port lead free ball valve is used in residential and commercial potable water applications, suitable for a full range of liquids and gases. This valve features a lead free brass body and adapter, female threaded end connections, adjustable packing gland, chrome plated lead free brass ball, virgin PTFE seats and seals, a bottom loaded blowout proof stem, and steel handle. The temperature range is minus 40 to 400 degrees F (minus 40 to 204 degrees C) and the pressure rating is 600 psi (41 bar) WOG non-shock and 150 psi (10.3 bar) WSP.

This 3/4 inch 2-piece full port lead free ball valve is used in commercial and industrial applications for a full range of liquids and gases. It features a lead free brass body with solder end connections, bottom-loaded blowout-proof stem, virgin PTFE seat, thrust washer, and adjustable stem packing seal, chrome plated lead free brass ball, lead free brass adapter and steel handle.

This 1/2 inch lead free anti-siphon vacuum breaker backflow preventer for hot or cold water prevents the reverse flow of polluted water from entering into the potable water supply due to backsiphonage. It consists of lead free construction, chemical resistant silicone seat disc, chrome hood, and an atmospheric vent to prevent spilling. It has a full size orifice to assure pipe size capacity and maximum flow. It is ideal for low flow, non-continuous hot or cold water health hazard applications such as on laboratory equipment.
