When a manufacturer of precision dispensing syringe systems required something new, they turned to Bio-Chem Valve. The company modified an existing valve product to create a compact, 3-way dual solenoid valve. The valve needed to be assembled on top of multiple syringes, and mounted side-by-side, while functioning in usual aspirate and dispense modes, as well as a wash cycle. Flexibility was necessary to accommodate changing requirements and speed was needed to allow fast needle changing. Bio-Chem Valve was developed a small valve solution that met these requirements. The dual-solenoid, 3-way valve features a rectangular body design with two ports opposite the common port, so the valves can be easily mounted side-by-side. It is capable of switching on demand to allow independent operation of each inlet port. The normally open and normally closed ports have four possible on/off combinations, offering the flexibility and speed to select desired pathway combinations for efficient, low cost flow switching and the wash cycle requirement. The new valve also saves on power usage, circuitry and number of controls.
