Caleffi 548 Series Hydro Separator-1-1/4" Sweat Union w/Insulation

Hydro Separator available in 1"-2" NPT & Sweat Unions. MAX operating pressure: 150 psi. Temperature range with insulation: 32-230 F. Medium: Water & Non-Hazardous Glycol solution. MAX percentage glycol: 50%.

Series 548 Hydro Separator This device consists of several different functional components, each meet specific requirements, typical of the circuits used in heating and air-conditioning systems. • Hydronic separator: To keep connected hydronic circuits totally independent from each other • Dirt remover: To permit the separation and collection of any impurities present in the circuits. Provided with a valved connection with discharge piping. • Automatic air vent valve: For automatic venting of any air contained in the circuits. Provided with a valved connection for maintenance purposes. The hydronic separator should be sized according to the maximum flow rate value at 2" 37 the inlet. The selected design value must be the greatest between the primary circuit and the secondary circuit. When a single system contains a primary production circuit, with its own pump, and a secondary user circuit, with one or more distribution pumps, operating conditions may arise in the system whereby the pumps interact, crating abnormal variations in circuit flow rates and pressures. The hydronic separator creates a zone with a low pressure loss, which enables the primary and secondary circuits connected to it to be hydraulically independent of each other; the flow in one circuit does not create a flow in the other if the pressure loss in the common section is negligible. In this case, the flow rate in the respective circuits depends exclusively on the flow rate characteristics of the pumps, preventing reciprocal influence caused by connection in series. Therefore, using a device with these characteristics means that the flow in the secondary circuit only circulates when the relevant pump is on, permitting the system to meet the specific load requirements at that time. When the secondary pump is off, there is no circulation in the secondary circuit; the whole flow rate produced by the primary pump is by-passed through the separator. With the hydronic separator, it is thus possible to have a primary production circuit with a constant flow rate and a secondary distribution circuit with a variable flow rate; these operating conditions are typical of modern heating and cooling systems.

Caleffi 132 Series QuickSetter Balancing Valve with Flow Meter-1" NPT: 3-10 GPM

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.
