The ultraminiature PCFCD-1N1 pressure- compensated flow-control valve, with a low-friction diaphragm, is designed to maintain a constant flow rate, regardless of variations. The customer-adjustable valve works with both liquids (incompressible fluids) and gasses (compressible fluids). The PCFCD-1N1 weighs only 48 gm, making it suitable when space, weight, and precise liquid flow control are critical. The valve controls flow rates of 0 to 4.2 gallons/hr of water (0 to 20 cu ft/hr of air). Maximum rated inlet supply pressure is 500 psig. The inlet and outlet ports are tapped 10-32. The PCFCD-1N1 is currently available in brass with Buna-N as the standard seal material.
