LFY Series 2- & 3-Way Isolation Solenoid Valve

This chemically inert internal pinch-tube valve is available in 2-way and 3-way configurations with zero dead volume. Intended for applications flowing aggressive fluids, this legacy valve features a unique internal pinch-block design which isolates the fluid path and minimizes internal volume. We offer high flow (1000 Lohms) and inert FFKM standard models that are readily available for connection to ¼-28 fitting systems.
