- 【Upgraded Waterproof Head】：Zone valve power head with an upgraded sealed wire gland and reinforced housing, helping protect the 4-wire cable from moisture in typical basement or utility-room installations and improving reliability in hydronic heating systems.
- 【Product Compatibility and Replacement Information】:The 40003916-026 Power Head is compatible with Honeywell V8043E series zone valves, including models V8043E1012, V8043E1020, V8043E1061, and V8043E1079. It is designed to replace the actuator head for these specific zone valves and operates with a 24VAC low voltage input. The power head includes an End Switch function for signaling when the valve reaches its fully open or closed position, ensuring compatibility with various control systems. This product is also a direct replacement for part numbers 40003916-021 (Lid Model) and 40004850-001 (Lid Model), providing a reliable solution for valve head replacements.
- 【24V AC Actuation with End Switch】：Low-voltage 24 V AC, 6 W actuator (0.32 A) with built-in end switch rated 24 V / 2 A, allowing the zone valve to signal a boiler or circulator pump when fully open for more efficient hydronic control.
- 【4-Wire, 18” Leads】：Supplied with four 18-inch leads—two yellow motor wires and two red end-switch wires—making it straightforward to swap out worn or failed zone valve heads with simple wire-to-wire connections in 2-way, normally closed, 4-wire systems.
- 【Install-Safe Operation】：mount the actuator firmly on the compatible valve body before applying power. Installing the head first helps protect the internal gear train and ensures smooth engagement with the valve stem during operation.
