Stepper-Controlled Proportional Valve 0-1200L/min
FC series proportional water 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.
FC1500 series proportional needle valve can reach flow rate up to 3000 L/min (106 SCFM) at 150 psig inlet pressure. Turndown ratio can reach up to 1: 400. Selection of flow sensors available for feedback signal.
FC20 series proportional control water flow valve is used for dosing, that can dispense as low as 1 mL of water. FC120 series valve can reach a life time of 10 million cycles of full open to full closure.
Takes 0-10V, 4-20mA or RS85 signal to change orifice. All models can customize wet material to stainless steel, consult factory for customization.
Proportional Flow Control Valve consists of PM series driver and FC series proportional flow valve. With an input signal either through analogue or digital, the needle inside the proportional valve moves proportionally to the signal. This series is able to control the flow rate of air and liquid with high resolution, high accuracy, and high repeatability. It is developed for industries that require a high degree of adjustment in flow rate.
Series PM driver provides series FC valve with the required power and control signal (step and direction). It controls the step of a bipolar stepper motor with an analogue signal (0-10 VDC/4-20mA/RS485 Modbus).
