Burkert 20016504 Type 3360 is an electromotive 2-way angle seat control valve designed for control tasks under demanding operating conditions. The electromotive actuator with a ball screw positions the control cone with high precision. It features a positioning speed of up to 6 mm/s that reacts quasi delay-free to process signals. Pressure variations or shocks in the medium are not transferred to the valve position. The actuator and valve are adapted to each other with a closed design and robust surface, ensuring hygienic requirements for fast and residue-free cleaning. The valve provides a degree of protection of IP65 / IP67 and high impact and vibration resistance.

Performance Specifications

Operating Limits for Medium Temperature and Operating Pressure

In addition to the maximum operating pressures, the application range of Burkert process valves is limited by the nominal pressure in accordance with the relevant standard.

Operating Limits for Ambient and Medium Temperature

The maximum permissible temperature for the environment and the medium are dependent on each other. The maximum allowable temperature curves of different device variants are shown in the temperature chart.

2	Devices with display
3	Devices with energy storage SAFEPOS energy-pack or fieldbus gateway, with/without display module

Product Design and Assembly

Design of Electromotive Valve Type 3360 AG2

The electromotive linear drive consists of a brushless DC motor, a gear, and a spindle system that transfers the force to the closing element. The integrated control electronics are controlled either by standard signals or via a fieldbus (digital). The electromotive linear actuator is designed to provide optimum efficiency, keeping the valve tight and in position even at the maximum specified medium pressure in a powerless standstill.

WARNING

Risk of injury from high pressure. Before working on the system or device, switch off the pressure and vent or drain lines.

TIP

If the supply voltage is not applied, e.g. during installation or in the event of a power failure, the valve position can be changed using the mechanical manual override. The mechanical manual control may be used in a de-energized state only, otherwise the device may be damaged.
