Water heating brass electric ball valve with manual switch, 3wire twocontrol actuator AC220V, 3way/2way. Available sizes: DN15, DN20, DN25, DN32 (3/4 inches, 2 Way). 3/4 inches 2 Way. Why this valve solves your problem Designed for reliable control of heated water lines: provides positive on/off or diverting control for water heating systems where safe, repeatable flow control is needed. Electric actuator with manual switch gives automatic control plus onsite manual override for commissioning or emergency use. Brass construction resists corrosion and provides long service life in hot water applications. Key benefits Precise control: 3wire twocontrol actuator with AC220V power enables remote open/close control with straightforward wiring. Manual override: builtin manual switch lets you operate the valve without power for maintenance or testing. Flexible configurations: available as 2way or 3way to suit isolation or flowdiverting applications. Multiple sizes: offered in DN15, DN20, DN25, DN32 to match common pipe diameters; includes 3/4 inches 2 Way option for easy compatibility. Main features and attributes Functionality: Electric ball valve for on/off and diverting control in water heating systems. Manual switch allows local operation. Actuator: 3wire twocontrol actuator, AC220V supply. Material: Brass valve body suitable for hot water service. Port options: 2way and 3way valve configurations available. Sizes: DN15, DN20, DN25, DN32. Includes 3/4 inches 2 Way specification. Typical use: Installed where automated or remotecontrolled shutoff/diversion of heated water is required. Compatibility and installation notes Intended for water heating and hot water distribution systems; compatible with standard pipe fittings corresponding to DN15–DN32 sizes. Power: requires AC220V supply for actuator operation and uses 3wire twocontrol wiring. Manual switch provides safe local control during power loss or maintenance. Use cases 1) Residential zone control: Automate hot water flow to an underfloor heating loop or a radiator circuit. Use the 2way valve to switch supply on/off per zone from a thermostatcontrolled AC220V actuator; use the manual switch for system checks. 2) System diversion for boiler/solar integration: Use the 3way valve to divert heated water between a domestic hot water tank and a secondary heating circuit, enabling automatic switching between sources while retaining manual override for service. What to expect in operation Stable open/close control under electric actuation with manual override for immediate shutoff. Durable brass body suitable for repeated cycling in water heating applications. Straightforward wiring and mechanical installation when matching valve size to existing piping. information Confirm required configuration (2way or 3way) and size (DN15, DN20, DN25, DN32). Note the AC220V 3wire twocontrol actuator and manual switch are integral to the unit.
