Compact Solenoid Valve

This compact gradient valve simulates a constant flow by utilizing rapid-cycling miniature solenoid valves to dispense gradients from multiple fluid streams in precise, repeatable proportions suitable for precision, high-purity diverting and mixing applications. An innovative armature drives the valve faster, with less energy, to assure controlled flow with repeatable opening and closing times. The gradient valves are designed for flexibility, with a rapid response time of only 2 ms to provide modulating flowrates at constant pressures to simulate a constant flow. A choice of compact, light-weight, spacesaving manifold layouts reconfigures the valves and ports to meet the unique physical space, size, and weight restrictions of the project. Every solenoid actuator on the flow selector valve is set to assure equal flowrates at the same pressure. The valves are offered in PTFE, PEEK and PPS. Diaphragm materials include PTFE, EPDM, Viton and perfluoroelastomer.
