The low pressure proportional pressure regulator can be categorised into1. low flow2. high flow3. economic typeThe low flow rate version is ideal for regulating air pressure in a small closed volume, applications include mini cylinder and microfluidics.The high flow rate version is suitable for dynamic process condition or regulating pressure in a bigger volume container.The economic type has accuracy of 0.5% F.S, it is also suitable for dynamic process, it is suitable for low pressure control in laser cutting machine.

FC series proportional liquid and gas flow control valve provides high precision flow control of liquid and gas.Repeatability can reach as high as 0.1% F.S with extremely low hysteresis. FC10 series proportional needle valve can reach flow rate up to 18 L/min (0.63 SCFM) at 87 psig inlet pressure.This valve is used for dosing, that can dispense as low as 1 mL of water. Takes 0-10V, 4-20mA or RS85 signal to change orifice. All models can customize wet material to stainless steel, consult a factory for customization.
