FUJIKURA VF PWM Proportional Flow Control Valve

• Current-controlled flow adjustment: Secondary-side flow can be adjusted through the input current for integration with automated control systems.
• Stepless flow control: Flow changes continuously according to the current value, enabling fine and smooth adjustment.
• PWM control capability: Pulse-width modulation can be used to control the valve in automated equipment.
• Low hysteresis and good repeatability: Low hysteresis supports stable flow performance during repeated operation.
• Compact manifold design: The Φ16mm body uses a manifold connection for installation in equipment with limited space.

Q1: What is the FUJIKURA VF Series?
A: The VF Series is a proportional flow control valve that provides stepless current-based flow adjustment and supports PWM control.

Q2: What is the standard VF model?
A: The standard model is VF-4-M.

Q3: What is the flow adjustment range of VF-4-M?
A: The secondary flow adjustment range is 7 L/min at a pressure setting of 20kPa.

Q4: How is the flow rate controlled?
A: Flow changes continuously according to the input current, enabling stepless adjustment.

Q5: Does the VF Series support PWM control?
A: Yes. PWM control is supported for integration with controllers and automated equipment.

Q6: What is the input signal range?
A: The maximum input current is 120mA, and the resistance is 47Ω.

Q7: What is the power consumption?
A: Power consumption is 2W or less at DC12V.

Q8: What connection method does VF-4-M use?
A: Code "M" indicates manifold mounting. Both the inlet and outlet port diameters are Φ3.2mm.

Q9: What is the operating temperature range?
A: The operating temperature range is 5 to 50℃.

Q10: What applications is the VF Series suitable for?
A: It is suitable for medical equipment, respirators, anesthesia machines, and compact systems requiring fine flow control.
