6628 2/2 & 3/2-Way Rocker Solenoid Valve
Brand: Burkert Fluid Control Systems
Direct acting medium separated 2/2- and 3/2-way Rocker Solenoid Valve for control of aggressive fluids and gases in analytical medical applications, the food industry, and also the chemical industry for dosing, filling, mixing and distribution.
The medium is in contact with fluid housing and seal material solely through the isolating diaphragm.
This valve with the new TwinPower actuator, robust screw-in connection and 0.86" (22 mm) installation width, will fulfil the highest requirements. The established rocker solenoid technology is characterized through full back pressure tightness, good rinsing capability and low internal volume.
Type 6628 is available in different technical versions and by virtue of several body options, it offers a perfect adaption in fluid applications.
