The Honeywell Resideo V4043A1002 is a normally closed, two-way, straight-through motorized zone valve with 18" (457 mm) electrical leads.  Features a 1/2" flare (5/8” copper) connection and operates at 0.08A, 120 VAC, 60 Hz, with a power consumption of 9.6 VA and a nominal actuation time of 15 seconds.  It includes a removable powerhead for easy servicing and a manual opener for operation during power failure.  UL Listed and CSA Certified for safety compliance.

Constructed with a brass body and seat, stainless steel stem, Buna-N rubber ball plug, and EPDM rubber O-ring packing.  It can withstand 52°C (125°F) ambient temperature and 5°C to 93°C (40°F to 200°F) fluid temperature range with 125 psi (862 kPa) static pressure and 20 psi (138 kPa) differential pressure close-off.  Offers a flow capacity of 3.5 Cv (3 Kv) and features spring-return-to-close valve action.

The V4043A1002 with 802360NA motor directly replaces the V4043A1044 zone valve.  Designed for use in closed-loop hydronic heating and cooling systems to control the flow of hot or chilled water or steam.  Intended for systems that do not contain dissolved oxygen, such as those without frequent fresh water makeup, it is ideal for cycling applications and can be installed without disassembling the valve body.
