DMIC’s PC1H Pressure Compensated Flow Control Valves maintain consistent flow rates within 5% despite upstream or downstream pressure fluctuations. Featuring a carbon steel body, stainless steel trim and integrated 5 PSI check valve, these valves provide adjustable metered flow in one direction and free flow in reverse. Available in sizes from ¼” to 1″, with pressure ratings up to 3,000 PSI, PC1H valves offer dual-taper needle adjustment, Chromaflow color-coded settings and multiple connection options for reliable hydraulic flow control.
