40003916-500 Series

Replacement Powerhead

APPLICATION

The new 40003916-500 series actuators are field

replacements for the powerheads on V8043 series

motorized zone valves.

These new powerheads are to be used with the new 5000

series valves. They feature a “Quick Fit” button at the side

that speeds up installation and service by allowing the

actuator to snap onto a 5000 series valve.

The 500 series actuators are also backward compatible

with the V8043 1000 series zone valves. When installing a

500 series actuator on a 1000 series valve body, it is

necessary to use screws to secure the two together.

INSTALLATION

CAUTION

Normally it is not necessary to remove the

powerhead from the valve body during installation.

The valve must be disassembled with the water flow

arrow pointing away from the manual opening or

lever slot.

NOTE: It is not necessary to drain the hydronic system if

the valve body assembly remains in the pipe line.

Removing a New-Style Actuator from a New-Style Valve

Body (See Fig. 1.)

1. Switch power supply OFF. Disconnect electrical

leads carefully, noting the position and color of each

lead. (Tip: label the wires indicating where they

belong before disconnecting them.)

2. Place the manual lever in the MAN. OPEN position.

3. Remove the actuator by fully depressing spring

release button and lift it straight off the body.

NOTE: The retaining spring presses on the outside of the

bearing hub, but this does not lock the actuator in

place. It is easy to remove the powerhead when

the “Quick Fit” button is fully depressed.
