BURKERT 6027 is a direct-acting plunger valve. The stopper and plunger guide tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. The coils are moulded with chemically resistant epoxy. An optional sliding ring bearing increases the service life with dry gases. Special seal technology is used for high-pressure applications. To reduce power consumption in operation, coils with Kick and Drop electronics assembly (double coil technology) are available. In combination with a plug in accordance with DIN EN 175301-803 Form A, the valves satisfy protection class IP65. NEMA 4X is available on request.

Safety Instructions

Danger due to high pressure and electrical voltage

• Before loosening lines and valves, turn off the pressure and vent the lines.
• Before working on or inside the device or the system, switch off the power supply and secure against reactivation.
• Observe the applicable accident prevention and safety regulations for electrical devices.

Risk of burns and escaping medium

• Do not touch the device with your bare hands during or immediately after operation due to hot surfaces.
• Make sure seals are properly seated to prevent escaping medium.
• Carefully screw the coil and cable plug together.

Installation Note

Installation position is any, preferably with the actuator on top. Before installation, check pipelines for soiling and clean if necessary. Install a dirt trap at the valve inlet (0.2...0.4 mm).
