6624 Twin Power 2/2 & 3/2-Way Solenoid Valve
Brand: Burkert Fluid Control Systems



Type 6624 combines the reliable and successful Rocker principle with a highly innovative new actuator. The Twin Power concept of this actuator reduces the size greatly without loss in performance.
Hence the 0.39" (10 mm) wide medium isolated rocker valve, 6624, with a 0.06" (1.6 mm) orifice and a pressure resistance of psi: 29 (kPa: 200, bar:2), provides the same performance as a traditional 0.62" (16 mm) valve. In addition, the integrated power reduction decreases the energy consumption by 75%.
In combination with other design features the heat transfer into the medium can be reduced to a minimum. In the design of the 6624, the main benefits lie in its excellent cleanability and a high reliability.
By using high performance materials the 6624 suits the handling of aggressive medium perfectly. The valve is available in a 2-way and 3-way version.
