Spartan Scientific, a manufacturer of standard and custom designed solenoid valves, has introduced its CRDV/S drain valve. This valve combines an electronic sensor with a solid-state integrated logic analysis circuit to determine the exact amount of time necessary to empty condensate from a pneumatic system. The technologically advanced CRDV/S allows only the necessary amount of compressed air needed to purge excess fluid. By eliminating dirty condensate buildup it also increases machine life by reducing the rust that clogs air components. The CRDV/S features media compatible materials, includes indicator lights for power and purge cycle, and has an environment-resistant package.
