Bürkert presents a flexible alternative to solenoid valves

With a new series of electrically controlled motor valves Bürkert expands the spectrum of components for fluid control. The new valves are designed for space-saving and energy-saving operation. They also achieve a very fine linear characteristic and low hysteresis in the control of fluid flows.

The new compact valves from Bürkert use two different drive and valve concepts, depending on the orifice size: the first is based on linear drive seat valves for orifices DN2 to DN6 (Type 3270: shut-off valve, Type 3280: proportional valve). For the larger orifices DN8 to DN25 the fluid technology specialists from Ingelfingen rely on rotary drive disc valves. They are likewise available as shut-off valves (Type 3275) and as proportional valves (Type 3285). In the seat valves, the direction of flow against the seat is from below. They feature high leak tightness and short closure times. In the disc valves the direction of flow against the seat is from above. They are impressive due to their pressure insensitivity. In the development of the new motor valves Bürkert focused especially on a compact design, even in the case of larger orifices. All sizes of the Types 3270 and 3280 are housed in a standard body with dimensions of 137 mm x 55 mm x 64 mm (HxWxD). For Types 3275 and 3285 there are three compact sizes due to the larger spectrum of orifices. The valve bodies are available in brass or stainless steel.

Technology with specific advantages

The new motor valves offer an ideal alternative to the known solenoid valves in less dynamic applications which do not require response times in the millisecond range. Compared with valves of competitors, the motor actuated valves from Bürkert are nevertheless very dynamic with closure times of only 2,5 s (about 4 s for disc valves). They also feature low energy consumption, due to negligible holding power for a defined valve opening position and extremely precise positioning thanks to high-quality electric stepper motors. In addition, they achieve a higher flow coefficient in comparison to solenoid valves with the same orifice. The compact valves can be used with combustible gases at pressures from 0 to 3 bar, with neutral gases and liquids up to 6 bar. Seals of FKM or NBR and a body of polyphenylene sulfide and polycarbonate make them very robust. The compact valves are designed for an ambient temperature from -10 to 60 °C and fluid temperatures from 0 to 70 °C.

Communication for the future

The electrical connection to the power supply, measuring lines and process controller is achieved in the standard version (with end position detection) by means of a standard M12 connector (8-pin). The integrated electronics facilitate commissioning by eliminating the need for additional control electronics. Additional versions of the motor-driven proportional valves will be added in the future: the positioner version (for fieldbus communication and with integrated displacement measuring system), as well as the process controller version, (based on the positioner version with additional sensor signal inputs).

The positioner and the process controller version rely consistently on the new Efficient Device Integration Platform (EDIP) developed by Bürkert to open the door to Industry 4.0 for its products. EDIP comprises numerous functions, compatible HMI devices and other innovative services to facilitate the system integration of new devices.
