FUJIKURA RV High-Flow Precision Vacuum Regulator

• High-precision vacuum control: Sensitivity is 0.13kPa, with repeatability within ±0.3kPa for fine and stable vacuum pressure adjustment.
• High-flow capacity: The regulator provides a flow rate of up to 270 L/min (ANR) for equipment requiring high vacuum flow.
• Direct-acting low-leakage design: Direct-acting control helps reduce air leakage and energy loss from the supply side.
• Low supply-pressure influence: Stable secondary vacuum pressure can be maintained when the primary supply pressure changes.
• Sensitive vacuum response: The regulator responds sensitively to secondary-side pressure variations for stable vacuum control.

Q1: What is the FUJIKURA RV Series?
A: The RV Series is a direct-acting precision vacuum regulator designed for high-precision and high-flow vacuum control.

Q2: What standard models are available?
A: Standard models are RV-1-2 and RV-1-3.

Q3: What is the difference between RV-1-2 and RV-1-3?
A: The main difference is the pipe port. RV-1-2 uses Rc1/4, while RV-1-3 uses Rc3/8.

Q4: What is the set pressure range?
A: The set pressure range is -1.3 to -100kPa, equivalent to -10 to -750mmHg.

Q5: What sensitivity does the RV Series provide?
A: Sensitivity is 0.13kPa, equivalent to 1mmHg.

Q6: What repeatability does the RV Series provide?
A: Repeatability is within ±0.3kPa, equivalent to within ±2.2mmHg.

Q7: What flow rate does the RV Series support?
A: The standard flow rate is 270 L/min (ANR), making it suitable for high-flow vacuum control.

Q8: What control structure does the RV Series use?
A: It uses a direct-acting structure that helps reduce air leakage and efficiently control supply pressure.

Q9: What is the operating temperature range?
A: The operating temperature range is 5 to 60℃.

Q10: What applications is the RV Series suitable for?
A: It is suitable for automation equipment and vacuum systems requiring high-precision, high-flow vacuum control.
