Strom Replacement 3 Port Valve Head

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.
