PTFE Multi-Channel Gradient Valves


NIV series gradient valves feature multiple 2-Way, Normally-Closed solenoids connected around a central body. This unique design provides a significant reduction in internal volume with enhanced mixing capabilities. Each actuator operates independently, allowing for the flow of various media to be mixed or for one media to be split into multiple streams. These multi-channel gradient valves are useful for solvent selection, stream splitting, flushing, and other automated applications.


Common industries that use these valves for the benefits of isolating the fluid from a mechanical valve include drug dispensing, laboratory equipment, wastewater, medical devices, chemical, food and beverage equipment, ceramic/glass/plastic, and bulk and solids handling.​
