Rotex High-Pressure Direct-Acting Solenoid Valve (typically from the Rotex 30111 / 20111 or similar 2/2 or 3/2 series).
It features a heavy-duty, square-block stainless steel valve body paired with a metallic stainless steel solenoid armature housing and a top-mounted DIN connector (IP65/weatherproof). Built for rugged industrial environments, this compact valve operates reliably without requiring a minimum pressure differential, making it ideal for high-pressure fluid line control and severe-service applications.
