The Strom replacement actuator head for 3 port mid-position motorised valves SSZVA302 used with Strom electric boiler systems. It allows you to renew a failed actuator without draining down or disturbing the existing valve body. Key Features Replacement head only for Strom 3 port mid-position zone valves SSZV2232. Demountable design so the actuator can be changed in situ without removing the valve body from the pipework. Spring-return operation with a manual lever for test and override of valve position. Suitable for fully pumped Y-Plan type systems controlling heating and hot water circuits. Wiring compatible with standard 3 port mid-position controls (live, neutral, earth and switched outputs). Typical Applications Domestic central heating systems using a single 3 port valve to share boiler output between radiators and hot water cylinder. Replacement of a worn, noisy or failed 3 port actuator on Strom systems where the valve body is still functioning correctly. Maintenance and servicing of Strom electric boiler installations requiring quick actuator changeover and minimal downtime. Technical Specification Product code SSZVA302 Product type Replacement actuator head for 3 port zone valve Valve compatibility Strom 3 port mid-position zone valves (e.g. SSZV2232) System type Fully pumped, Y-Plan style heating and hot water systems Function Motorised mid-position control of heating and hot water circuits Installation Demountable head, changeable without draining the system Operation Spring-return actuator with manual lever Wiring Standard 3 port mid-position wiring (L, N, E and switch wires) Supply voltage 230 V AC, 50 Hz (typical for domestic motorised valve heads) Power consumption Approx. 6 W (typical actuator load) Ambient temperature (head) Up to 50 °C (typical rating for motorised valve actuators) Flow temperature (valve body) Typically up to 88 °C when used with Strom boilers Applications Domestic sealed or open-vented central heating systems Notes Supplied as actuator head only; valve body is not included. Always isolate mains power before replacing the actuator head. Install in accordance with Strom boiler and system wiring schematics.
