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.
Wilo Classic Star S 21FX 3 Speed Cast Iron Circulator, Rotated 90 Flange
Wet rotor circulation pump, with flanged connection. (Flange parallel to shaft). Pre-selectable speeds to adjust the capacity on "S" versions. Cast iron body for hot-water heating systems of all kinds, industrial circulation systems, cold-water systems and air-conditioning systems.
Grundfos UP15-29SF 1/8HP, stainless steel, flanged Circulator Pump, primarily used in open loop heating systems, such as radiant, solar, hot water recirculation as well as chilled water cooling and many others.
Wet rotor circulation pump, with flanged connection. (Flange parallel to shaft). Cast iron body for hot-water heating systems of all kinds, industrial circulation systems, cold-water systems and air-conditioning systems.
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.

In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. The dirt separator separates off these impurities, which are mainly made up of particles of sand and rust, collecting them in a large collection chamber, from which they can be removed even while the system is in operation. This device is capable of efficiently removing the smallest particles, with low head loss.

Grundfos 1/6 HP 115V Circulating Pump Cast Iron Body
The Grundfos UP26-120 U is a cast iron circulator pump for closed circulation of water. The Grundfos model utilizes a two-pole, single phase motor at 1/6 (0.16) HP and produces a flow range of 0-19 GPM and a head range of 0-38 ft. The Grundfos UP26-120 U circulator pump functions at 115V, 2.15 Amp, and 60Hz, and has a maximum pressure of 145 PSI. The optimal water temperature for this Grundfos circulator pump model is within the 32-203 F range.
The Grundfos UP26-120 U circulator pump utilizes a 1-1/4 inch union connection.
The AutoFill™ automatic filling valve is a pressure reducing valve with
a compensating seat, an inlet filter, a shut-off valve and a check valve.
It is installed on the water inlet piping in sealed heating systems, and
its main function is to maintain the pressure of the system to a preset
value, automatically filling up with water as required. This valve has been
designed as pre-adjustable, which means it can be adjusted at the required
pressure value before charging the system. After installation, during the
filling or topping-off phase, the water feed will stop automatically when the
set pressure is reached. There are no levers to flip or valve to close. Preassembled with the backflow preventer, it features an atmospheric vent
which is designed to protect drinking water systems from return flow, caused
by back-siphoning or backpressure, of contaminated fluids. The 573 series
has been specifically certified to standards CSA B64.3 and ASSE 1012.
