VALVE PACKAGES (cont)

Two-Way Motorized Control Valve

The 2-way motorized valve motor drives valve open and a spring returns valve to normally closed position (no water ¯ow with unit OFF).

Supply connection at coil will be swage ®t for ®eld braze (standard) or union (option). Return connection at coil will be factory brazed if isolation valve only. Addition of any other component will require swage ®t for ®eld braze or optional union connection.

Check job speci®cations for system pressure, pres- sure drop limitations and ¯ow rate prior to selecting valve package components or valve package size (1¤2 , 3¤4 , etc.).

2-PIPE SYSTEM (One Valve Package) or 4-PIPE SYS- TEM (Two Valve Packages) Application:

·2 Pipe - Hydronic Heating Only

·2 Pipe - Hydronic Cooling Only

·2 Pipe - Hydronic Cooling with Total Electric Heat

·4 Pipe - Hydronic Cooling and Heating

NOTE: A 1¤4-in. bypass line is included in the piping pack- age when a 2-way valve is speci®ed with a control pack- age containing an automatic changeover device.

Two-Way Motorized Control Valve with Aquastat Bleed Bypass Line

The 2-way motorized valve motor drives valve open and a spring returns valve to normally closed position (no water ¯ow through coil with unit OFF).

The aquastat bleed bypass bleeds a small amount of water from supply to return when control valve is closed (required for system water temperature sensing by aqua- stat). Aquastat (A) clips on supply line upstream from aquastat bleed bypass (as shown at right). It senses system water temperature to prevent cooling operation with hot water in system piping or heating operation with chilled water in system piping. Additional aquastat re- quired to lock out the optional auxiliary electric heat when hot water in system.

Supply and return connections at coil will be swage ®t for ®eld braze (standard) or unions (option).

Check job speci®cations for system pressure, pres- sure drop limitations and ¯ow rate prior to selecting valve package components or valve package size (1¤2 , 3¤4 , etc.).

2-PIPE SYSTEM (One Valve Package) Application:

·2 Pipe - Hydronic Cooling and Heating

·2 Pipe - Hydronic Cooling and Heating with Auxiliary Electric Heat

NOTES: Additional aquastat required as noted above.
