BURKERT 307272 (Type 5404) is a servo-assisted 2/2-way piston valve designed for demanding applications. 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 valves satisfy degree of protection IP65. This specific model is configured as a steam variant (NA07) with a 13 mm orifice, suitable for temperatures up to +160 °C.

Safety & Installation

Risk of injury from high pressure and electric shock

• Before working on the system or device, switch off the pressure and ventilate or empty the lines.
• Before working on the system or device, switch off the power supply and secure against reactivation.

Risk of burns/fire

Keep the device away from highly flammable substances and media and do not touch with bare hands if operated continuously.

Installation Position

As required, preferably with actuator upright. Install a dirt trap upstream of the valve inlet (≤ 500 μm).
