DESCRIPTION

The Bell & Gossett Automatic Flow Limiting Valves (AFLV) are

designed to automatically control the flow in piping system to

selected preset limit. As pressure differential increases, a

cartridge inside the valve body reduces the flow area to

accurately maintain the pre-selected flow rate.

Operational Limits

Maximum Operating Temperature: 250ºF (121ºC)*

Maximum Operating Pressure: 300 psig (206

9 kPa)*

Differential Pressure Flow Control

2 to 60 psig (14 to 414 kPa) nominal

INSTALLATION INSTRUCTIONS

1. For installing NPT Connections:

a) Install the AFLV in the piping system/circuit where it is

desired to maintain the flow at a preselected value.

Apply pipe joint compound sparingly to the male pipe

threads only.

b) Install the unit so that the flow arrow on the body

housing points in the direction

of flow.

c) Supports both sides of the unit with wrenches during

installation to prevent putting stress on the joint

joining the two sections.

2. For installing Sweat Connections:

a) Clean tube ends and valve connections thoroughly

according to good piping practices with a fine grade

emery cloth or fine grit sandpaper.

SAFETY

INSTRUCTION

This safety alert symbol will be used in this manual to draw

attention to safety related instructions. When used, the safety

alert symbol means ATTENTION! BECOME ALERT! YOUR

SAFETY IS INVOLVED! FAILURE TO FOLLOW THESE IN-

STRUCTIONS MAY RESULT IN A SAFETY HAZARD.

CAUTION: The generous use of pipe joint com-

pound when installing the AFLV will foul the valve

operating mechanism preventing it from functioning

properly. Pipe joint compound must be conservatively

applied to male threads only. Failure to follow this

instruction can result in moderate personal injury and/or

property damage.

INSTALLER: PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.

* Refer to chart A for solder joints for limitations.

CAUTION: The use of PTFE impregnated pipe

compound and PTFE tape on pipe threads pro-

vides lubricity, which can lead to overtightening and

breakage. Do not overtighten. Failure to follow this

instruction can result in moderate personal injury and/or

property damage.

b) For soldering, use 95-5 (Tin-Antimony) solder and a good grade of flux. c) Use a torch with a sharp pointed flame. d) When sweating the joints, first adjusting the Automatic Flow-Limiting Valve in the full open position, then wrap the valve with a cool wet rag and then direct the flame with care to avoid subjecting AFLV to excessive heat. Allow the valve to cool before touching or operating. e) Check the soldered connection for leaks.
