Special Features

  • 【For Hydronic Heating Systems】：This 3/4” sweat connection zone valve (Model V8043E1012) is a two-way, normally closed valve designed for closed-loop hot-water heating systems without dissolved oxygen. It operates on 24V AC, 50/60Hz, providing stable thermostat-controlled flow regulation for residential and light-commercial hydronic applications. This valve is an ideal choice for zone valves for boilers, ensuring effective water flow management in boiler systems. For maintenance or replacement of the actuator, consider the 40003916-026 or 40004850-001 actuators, which are compatible with the V8043E1012 zone valve and offer seamless integration for reliable boiler system performance.
  • 【Upgraded Sealed Wire Gland】：Features an upgraded sealed wire gland and strain-relief cable entry, helping protect the 4-wire lead set from moisture, condensation, and mechanical pull during installation. This enhanced cable protection improves durability in basement, boiler-room, and utility-room environments.
  • 【Forged Brass Body & Heat-Rated Components】：Constructed with a forged brass valve body, stainless-steel stem, and heat-resistant internal components. Rated for 125 psi system pressure, 200°F (93°C) fluid temperature, and 125°F (52°C) ambient temperature for reliable long-term operation in hydronic heating loops.
  • 【4-Wire Design with Built-In End Switch】：Includes a built-in SPST end switch and four 18-inch leads—two yellow motor wires and two red switch wires—for coordinated control with boilers, circulators, or thermostats. The end switch confirms full-open position, helping improve system efficiency and automation.
  • 【Manual Opener & Service-Friendly Design】:A manual lever allows temporary operation during power loss and automatically returns to normal position when power is restored. The actuator assembly can be serviced or replaced without draining the system or disconnecting plumbing, simplifying maintenance in existing heating loops.
