Burkert Type 6213 EV is a servo-assisted diaphragm valve. The spring coupling of the diaphragm supports the opening process in the valve. In its standard variant, the valve is suitable for deployment with liquids. A minimum differential pressure is required for full opening. For gas and vacuum applications, a special variant is available (HP00) that opens the valve without differential pressure. Various diaphragm materials are available depending on the actual application.

Features

• Servo-assisted diaphragm valve with nominal diameter of up to DN 40
• Spring coupled diaphragm opens without differential pressure
• Damped design for low noise
• High flow rate with compact design
• Energy-saving double coil technology with kick and drop variant

Circuit Function

Circuit function A (CF A): 2/2-way solenoid valve, servo-controlled, normally closed.

Installation & Maintenance

Risk of injury from high pressure

Before loosening lines or valves, switch off the pressure and vent the lines.

Risk of injury from electric shock

Before reaching into the device or the system, switch off the power supply and secure it against reactivation.

Installation Approach:

1. Clean pipelines of any contamination.
2. Install a dirt trap upstream of the valve inlet (≤ 500 µm).
3. Hold the device on the body using an open-end wrench and screw into the pipeline. Do not use the solenoid as a lever arm.
4. Observe the flow direction: the arrow on the body indicates the flow direction.

Solenoid Installation:

1. Slide solenoid housing onto core guide tube.
2. Screw solenoid with nut. Observe tightening torques (5 Nm for AC10, 10 Nm for AC19).
3. Always tighten nut with an open-end wrench. Using other tools may damage the device.
