B315-029-029 LRX24-MFT
B315-029-029, 6-Way, Characterized Control Valve
Chrome Plated Brass Ball and Nickel Plated Stem, 1/2“, NPT female ends
Application
The 6-way characterized control valve is ideal for chilled beams, radiant ceilings,
and Fan Coil Units offering reduced wiring by using a single actuator instead
of two. It eliminates the need for a change over valve and enables the use of a
single coil for heating and cooling.
Operation
A loop pressure relief is designed into port number two (2). This allows the
increased pressure to dissipate to the supply loop on port number one (1). This
is intended to release any pressure build up in the loop (coil) when the valve
is in the closed position and is isolated from the system expansion vessel. The
change in pressure occurs due to a change in the media temperature in the coil
while isolated from the pressure vessel. The pressure relief does not affect the
effi ciency of the system because cross-fl ow cannot occur between the heating
and cooling loops. The system loops (heating/cooling) should share a common
expansion vessel to keep the system pressure and volume balanced.

The control valve can be mounted either vertically or horizontally. Do not install
the valve with the stem pointing downwards.
A single expansion tank is recommended to ensure same pressure on
the heating and cooling loops, this helps to maintain energy efficiency by
eliminating migration of water from the cooling to the heating loop.
Maintenance: 6-Way characterized control valves and rotary actuators are
maintenance free.

Wiring Diagrams
INSTALLATION NOTES
Actuators may be connected in parallel. Power consumption and input
impedance must be observed.

Actuators may also be powered by 24 VDC.
Actuators Hot wire must be connected to the control board common. Only
connect common to neg. (-) leg of control circuits. Only connect common to
neg. (-) leg of control circuits. Terminal models (-T) have no-feedback.
A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2 to 10
VDC.

For triac sink the common connection from the actuator must be connected
to the hot connection of the controller. Contact closures A & B also can be
triacs. A & B should both be closed for the triac source and open for triac
sink.
