Description
The Type 6628 is a direct-acting, media-separated rocker-type solenoid valve in a 2/2-way or 3/2-way version. It is used to control aggressive liquids and gases and is used, among other things, in medical analysis technology, the food industry, and the chemical industry for dosing, filling, mixing, and distributing. Since a separating diaphragm isolates the medium from the actuator, the medium comes into contact only with the body and seal material.
This is made possible by the innovative TwinPower actuator, which meets the highest requirements in combination with a robust screw fitting and a width of only 22 mm. The proven rocker technology also ensures full back-pressure tightness, good flushability, and a low internal volume. The Type 6628 is available in a wide variety of technical versions and, through various fluidic body options, offers a precise fit to the respective application.
- 22 mm compact design up to nominal size 3.0
- Separating diaphragm for high chemical resistance
- Universally applicable in NC, NO, and as a 3-way valve modes of operation
- Full back-pressure tightness through the rocker principle
- Minimal internal volume combined with good flushability
