LEGEND For Fig. 1

Component Sizing Ð 1¤2 nominal (for 5¤8 OD copper tubing) or 3¤4 nominal (for 7¤8 OD copper tubing).

Manual Air Vent Ð Standard component - Brazed into high point of hydronic cooling and/or heating coil circuit.

Automatic Air Vent Ð Brazed into high point of coil circuit.

Coil Connections (Positions A & B) Ð When isolation valve only is added to supply or return line, the isolation valve will be factory brazed to the coil stub-out. Addition of any other component or connection to the supply or return line will change the respective coil connection(s) to one of the following:

STANDARD: Swage ®tting for ®eld braze.

OPTION: Union(s) added by factory for ®eld connection.

Service Fittings (Positions C & D) Ð Optional ®ttings for attaching pressure/temperature sensing devices to obtain pressure drop or temperature differential accross coil. Used with ball valve or balance valve where extremely accurate water ¯ow balancing is required.

GAGE COCK: Pressure test only - In supply and return lines.

PRESSURE TEST PORT: Pressure test only - In supply and return lines.

INSERTION TEST PORT: Pressure/Temperature test - In supply and return lines.

Water Flow Balancing (Positions E, F, & H) Ð Only one device per total valve package to be used for balancing water ¯ow through the coil. When isolation valve (ball valve or ball valve with memory stop at positionH) is used for water ¯ow balancing, do not specify additional balancing device at positionE or F. When balancing device is speci®ed at position E or F, isolation valve does not require balancing feature at position H (See exception, 3-way motorized valve).

CIRCUIT SETTER: May serve as a positive shut-off valve in lieu of isolation valve at position H (check service requirements).

BALANCING VALVE: Check speci®cations for service ®tting requirements.

FIXED FLOW: No balancing required - When there are more devices on the supply line of the valve package than on the return line, the factory may move this device to position E to ®t valve package within allotted space. Consult your factory representative to match the available ®xed ¯ow valve to your job requirements.

Strainer (Position G) Ð Does not include blow down ®tting and should not be used in lieu of main piping strainers.

Isolation Valves (Positions H & J) Ð Normally requires one each on supply and return line (see exception under circuit setter). When position H is used for balancing (ball vall or ball valve with memory stop), check speci®cations for service valve requirements.

GATE VALVE: Shut-off only - Do not use for balancing.

BALL VALVE: Shut-off/balance - No memory stop.

BALL VALVE WITH MEMORY STOP: Shut-off/balance - Memory stop allows re-opening to balance point after usage as a shut-off.
