BURKERT 353014 (Type 6213) is a servo-assisted 2/2-way 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.

The valve features a brass body with a G 1 1/2 internal thread, an EPDM seal, and operates at 230-240 V (50/60 Hz). It is designed for a nominal pressure range of 0 to 10 bar and is suitable for neutral media with temperatures ranging from -30 °C to +90 °C.

Safety and Installation

DANGER!

Risk of injury from high pressure in the system 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. Observe the applicable accident prevention and safety regulations for electrical devices.

WARNING!

Risk of injury due to improper installation Installation must be carried out by authorised technicians only and with the appropriate tools. Secure the system against unintentional activation and ensure a controlled restart after installation.

Before Installation:

• Clean pipelines of any contamination.
• Install a dirt trap upstream of the valve inlet (≤ 500 µm).
• Installation position: any, preferably with actuator on top.

Installation:

NOTICE!

Breaking hazard Do not use the solenoid as a lever arm. Hold the device on the body using an open-end wrench and screw into the pipeline.

• Observe the flow direction: the arrow on the body indicates the flow direction.
