Description
The Resideo V4043E1003 Zone Valve is a 1/2″ sweat connection valve that is used in steam and hydronic heating systems. This normally closed valve has a 3.5 Cv flow coefficient to let you adjust the flow of steam or water in your HVAC system to your advantage. This is a 2-way, straight-through valve with a brass valve body, an EPDM rubber ball and a stainless steel stem for long service life and maximum reliability. It is driven by a 120V actuator with an opening time of 15 seconds and effectively controls the flow of steam or water to particular zones in a heating system.
