The DMIC FC1M Brass Inline Flow Control Valve is a device designed to regulate the flow of fluid in one direction, equipped with a built-in check valve to ensure flow only occurs in the intended direction. Constructed from brass barstock, it is available in sizes ranging from 1/8" to 1" and can withstand working pressures of up to 2,000 PSI (with the 1" size rated for 500 PSI). With its dual taper needle design, it allows for precise metering at low flow rates and quick response at higher flow rates, offering flexibility across different applications. Its color-calibrated design simplifies adjustment, while the standard set screw prevents unauthorized tampering. Additionally, DMIC offers optional "fine" needle profiles for OEM production quantities, enhancing customization options for specific needs.
