The Resideo V8043E1137 is a two-way spring-return zone valve for hydronic heating, boiler, and radiant heat systems. It uses a 24V AC actuator (7.7 VA, 0.32A) with normally closed, spring-return operation and an integral N.O. SPST end switch rated 50 VA pilot duty at 24V or 4.4A running/26.4A inrush at 120V. Connections are 1" NPT with a 10 Cv flow rating, 125 psi static pressure rating, and 6.5 psi differential close-off. Body construction is brass with a stainless steel stem, Buna-N ball, and EPDM packing, suited for fluid temperatures from 50°F to 200°F and 125°F maximum ambient.
Installation is rated intermediate difficulty using basic tools; Teflon tape and a zone valve actuator replacement kit are commonly used during service. A manual opener lever permits manual flow in the event of a power or actuator failure.
