APPLICATION:
The V8043 Motorized Zone Valve provides two-position
(open-close) control of supply water for baseboard radiation,
convectors, fan-coil units, etc. It uses a two-wire, 24-volt con-
trol circuit and requires a SPST thermostat. Integral end-switch
models permit the sequencing of auxiliary equipment.
FEATURES:
•
Quiet, dependable operation is provided by motor-operated
powerhead and swing-type ball valve.
•
Unique rotating ball plug that seats on a different part of its
surface on each closing.
•
Closes against the flow of water to assure quiet operation.
•
Manual opener moves ball away from seat allowing valve
to be installed without disassembly.
•
Manual operation on power failure.
•
Easy servicing because the entire powerhead assembly can
be replaced without removing valve body from line. Op-
tional accessory fittings can be provided to facilitate con-
venient removal of the entire zone valve unit.
•
Low power requirements allow four valves to be operated
from a single 40 VA transformer.
•
Integral end-switch on F & G models to permit sequencing
of auxiliary equipment.
•
Choice of sweat, female NPT and flare (with union-flare
adapters) body styles.
•
Compact construction permits fitting under cover of
most baseboards,
