BURKERT 307326 (Type 5404) is a servo-assisted 2/2-way piston solenoid valve designed for steam applications (variant NA07). A minimum differential pressure is required for the valve switching function. The solenoid coils are moulded with high-quality epoxy resin. In combination with a plug to DIN EN 175301-803 Form A, the valve satisfies degree of protection IP65.

Safety Instructions

WARNING

Risk of injury due to high pressure and escaping medium Switch off the pressure before working on the device or system. Vent or drain the lines.

DANGER

Risk of injury from electric shock Switch off the power supply before working on the device or system. Secure against reactivation. Always connect protective conductor and check electrical continuity between solenoid and body.
