Caleffi Series 676 Two-way Thermoelectric Zone Valve
Zone valves are used to control hot and chilled water in heating and air conditioning
systems. Coupled with an electro-thermal control actuator and
managed by a room thermostat, they allow automatic on/off control of the
hydronic circuit on which they are installed.
Their special feature is their compact size and they can therefore be installed
almost anywhere including baseboard or directly in fan-coil units.
Grundfos UP15-29SU model circulator incorporates a stainless steel body design and 1-1/4" union connection, smaking it suitable for a wide range of open and closed loop radiant heating, hydronic heating, hot water recirculation, solar & other applications.
Balancing Valve with Flow Meter, offers direct reading of flow rate, no sight gauge clouding or scaling. Has brass valve body and flow meter, rotatable valve for flow rate adjustement, and graduated scale flow meter with magnetic movement flow rate indicator. MAX working pressure: 150 psi. Temperature range: 14-230 F. Max percentage of glycol: 50%.
The 132 series balancing valve accurately sets the flow rate of heating and cooling transfer fluid
supplied to fan coils and terminal units or where flow balancing is required in solar thermal
systems. Proper hydronic system balancing ensures that the system operates according to design
specifications, providing satisfactory thermal comfort with low energy consumption. The flow
meter is housed in a bypass circuit on the valve body and can be shut off during normal operation.
The flow meter permits fast and easy circuit balancing without added differential pressure gauges
and reference charts. The balancing valve is furnished with a preformed insulation shell to
optimize thermal performance or both hot and cold water systems.
Grundfos UPS15-35SFC is a 1/6HP, 3-Speed Circulator Pump with stainless steel housing, suitable for a wide range of open loop and closed loop applications, including radiant heating, hydronic heating, solar, hot water recirculation, chilled water cooling and many others. 3 speeds of the Grundfos UPS15-35SFC model allow to adjust pump's parameters to match system requirements and achieve optimal performance.
The gas pressure switch is mounted on the casing of the water heater adjacent to the heater's thermostat/gas control valve. It
should be mounted close enough so that the supplied 1/4" tubing will reach from the gas pressure switch fitting to the thermostat/gas valve pressure tap port. The two provided screws are self-tapping and drilling. The screws do not require the use of a drill and their 1/2" length assures that the inner tank will not be penetrated
Pro-Tek® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems.
Pro-Tek® 922 is a concentrated corrosion inhibitor treatment specially formulated for hot water closed loop heating systems. Many water sources used in hydronic heating systems can be very corrosive to metals when heated. Pro-Tek 922 will help to reduce corrosion on aluminum, brass, copper, iron, and stainless steel. Pro-Tek 922 has also been tested and is compatible with standard PEX and Onix tubing typically used in hydronic installations.
Grundfos Brute Three Speed Bronze Recirculator Pump
The Grundfos UPS26-99BFC (52722518) model incorporates a three speed motor for increased versatility, a built-in check valve and a bronze housing for ehnaced corrosion resistance. The wet rotor design allows it to be virtually silent while operating, while built-in motor protection assures long life of the circulator. Performance parameters (flow rates and pressure drop) of the Grundfos UPS26-99BFC model make it well suited for a wide range of applications, from radiant and hydronic heating, to domestic hot water recirculatio, solar, chilled water cooling and many others.
Z-one valves are used to automatically shut-off the flow or redirect hot and
chilled water in hydronic heating and air conditioning systems. The motorized two position, on/off/, spring return A1 series actuator has an
end mounted push button for quick installation to valve body. The actuator is
equipped with or without auxiliary switch and configured Normally closed or
Normally Opened with wire or terminal connections.
The thermostatic mixer is used in systems producing domestic hot water or in radiant panel heating systems. Its function is to maintain the temperature of the mixed water supplied to the user constant at the set value when there are variations in the supply conditions of the incoming hot and cold water.
The valve has been specifically certified to ASSE 1017.

The zero leakage high temperature zone valve body Z2 series is 2-way straight
through and the valve body Z3 series is 3-way diverting. The Z1 series
actuator is easily attached by a push button lock and without tools.
The high temperature and high close-off performance characteristics of these
zone valves, combined with the compact size, makes them suitable to fit inside
baseboard or directly in fan coil units.
