Electrically actuated quarter-turn valves offer a wider range of options
20 January 2014
Bürkert Fluid Control Systems has introduced the 3003 and 3004 model electrically operated actuators, which offer fast and reliable control and are designed to support many applications from 20Nm up to 100Nm.
The versatility of the design allows the valves to be powered by a wide range of both ac and dc supplies, as well as offering analogue control inputs and outputs. Furthermore, the modular design of the valves enables additional features such as extra limit switches, potentiometers and emergency supplies to be connected.
The material and component selection of these valves has been designed to provide maintenance-free operation even in harsh environments with the housing constructed from flame resistant material and a built-in torque limiting device to ensure safe and reliable operation.
With 3003 offers IP66 protection, built-in mechanical limit stops and a visual position indicator. The Type 3004 valve, which is classified as ATEX II 2 GD Ex d II B T6 and rated to IP67, is suitable for installation in Zone 1 hazardous areas.
This valve is also more powerful than the Type 3003, offering a maximum torque of 300Nm, while still offering similar options for the supply voltage and the analogue input and output signals.
