Motorised 2-way zone valves SF...
Motorised 2-way zone valves for heating, cooling and solar circuits. The valves are controlled via an electric motor and closed when currentless. Mounting of up to two auxiliary switches is possible. The valves are equipped with an external lever for emptying and filling the pipe system. The lever permits manual positioning of the shut-off in an intermediate position. The reset is automatic as soon as the valve is electrically powered again.
