Hello,
Please see the below product specifications. Hopefully this helps.

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. Quick Fit actuator provides easy snap on and off connectionto the valve assembly.

FEATURES:
• Quiet, dependable operation is provided by motoroperated powerhead and swing-type ball valve.
• Unique rotating ball plug that seats on a different part ofits surface on each closing.
• Closes against the flow of water to assure quiet operation.
• Manual opener moves ball away from seat allowing valveto be installed without disassembly.
• Manual operation on power failure.
• Easy servicing because the entire powerhead assemblycan be replaced without removing valve body from line.Optional accessory fittings can be provided to facilitateconvenient removal of the entire zone valve unit.
• Low power requirements allow four valves to be operatedfrom a single 40 VA transformer.
• Integral end-switch on F & G models to permitsequencing of auxiliary equipment.
• Choice of sweat, female NPT and flare (with union-flareadapters) body styles.
• Compact construction permits fitting under cover ofmost baseboards,
