V8043C, D, F & G
Motorized Zone Valves
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 control 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.
Optional accessory fittings can be provided to facilitate
convenient 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.
