The compact valves use two different drive and valve concepts, depending on the orifice size (Picture: Bürkert)

The 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 compact valves use two different drive and valve concepts, depending on the orifice size: the first is based on linear drive seat valves for orifices of DN2 to DN6 (Type 3270: shut-off valve, Type 3280: proportional valve). For the larger orifices of DN8 to DN25 the manufacturer relies 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. The valves offer a low energy consumption, due to negligible holding power for a defined valve opening position and precise positioning due to high-quality electric stepper motors. In addition, they achieve a higher flow coefficient in comparison to solenoid valves with the same orifice. The valves can be used with combustible gases at pressures from 0 to 3 bar, with neutral gases and liquids up to 6 bar. Seals made of FKM or NBR and a body made of polyphenylene sulfide and polycarbonate make them very robust. The valves are designed for an ambient temperature between -10 and 60 °C and fluid temperatures between 0 and 70 °C.
