HYDRONIC ZONE VALVES
(2 WIRE)
The contact arrangement of the switch is constructed so that
when the shaft of the motor revolves 90° a new set of stationary
and moving contacts makes, while the old set breaks. Fig.1.
The schematic shows the valve in the closed position. As the
The zone valve is designed to turn in one direction, stopping
every 90° in either the open or closed position, depending on
thermostat demand. The motor position is controlled by a wafer
switch attached to the motor shaft.
PRINCIPLE OF OPERATION
Maximum water temperature: 240°F (115°C)
Maximum system pressure: 50 PSI
Differential across valve: 15 PSI
Electrical Rating:
Valve motor: .2 Amp. Max at 25 VAC
(.40 Amp.) when valve is in open position.
Auxiliary Contacts: Do not exceed 2.0 Amp. at
25 VAC (Terminals 2 and 3)
NOTE: The valve motor draws more than .2 Amp. while it is
opening. For this reason, do not use more than the
All guarantees are void if these specifications are exceeded.
recommended number of valves per transformer as
shown on pages 3 and 4.
Thermostat: Use two-wire thermostat with .2 Amp. anticipator
Timing: From full close to full open–Approx. 45 seconds
From full open to full close–Approx. 60 seconds
Friction loss equivalents:
3/4" valves – 2-1/2 ft. copper tubing
1" valves – 4 ft. copper tubing
1-1/4" valves – 7 ft. copper tubing
SPECIFICATIONS
This zone valve motor is intended for use with a low voltage
system; do not use this zone valve with a millivolt or line voltage
system. If in doubt about whether your wiring is millivolt, line or
low voltage, have it inspected by a qualified heating contractor
or electrician.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical codes and
ordinances.
To prevent electrical shock and/or equipment damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.
To prevent injuries from scalding always drain system
before unlatching valve assembly from body.
Do not use on circuits exceeding specified voltages.
Higher voltages will damage control and could cause
shock or fire hazard.
PRECAUTIONS
These water valves provide a low cost system of zoned tem-
perature control wherever hot water is the heating medium. In
new construction, the heating piping system can be laid out to
produce any number of independent temperature controlled
zones by use of these valves.
In existing buildings, a variety of zone heating combinations can
be obtained, depending on the particular -piping lay-outs. Each
zone requires one water valve and one thermostat, but only
one circulator is required for the entire system. New con-
struction properly piped, will not require flow control valves,
since the water valve itself performs this function.
Existing construction, where flow control valves have been
installed, will operate quite satisfactorily without removing the
existing flow control valves.
If in “Closed” position, valve may be opened by turning dial
clockwise with your thumb until word “Open” appears. When
power is resumed, valve will automatically return to command of
room thermostat.
