FUJIKURA RB Compact General-Purpose Regulator

• Compact and lightweight design: The regulator weighs approximately 130g, helping save installation space and reduce component weight.
• High-flow capability: The compact body provides excellent pressure and flow characteristics for equipment requiring both small size and air flow capacity.
• Push-lock knob: The knob can be pushed down after pressure adjustment to secure the setting and reduce accidental changes.
• Relief and non-relief models: RB relief and RB・NR non-relief models are available for different secondary-side pressure control requirements.
• Manifold and clean-room options: Manifold mounting is supported, and clean-room-compatible specifications are available by custom order.

Q1: What is the FUJIKURA RB Series?
A: The RB Series is a compact general-purpose regulator with a push-lock knob for applications requiring compact size and air flow capacity.

Q2: What standard models are available?
A: Standard models include RB-7-1, RB・NR-7-1, RB-7-2, and RB・NR-7-2.

Q3: What is the set pressure range?
A: The set pressure range is 0 to 0.7MPa.

Q4: What is the difference between RB and RB・NR?
A: RB is the relief type and can release secondary-side pressure when the setting is reduced. RB・NR is the non-relief type and does not actively vent secondary pressure.

Q5: What pipe port sizes are available?
A: Rc1/8 and Rc1/4 pipe ports are available, represented by final model codes "1" and "2."

Q6: What repeatability does the RB Series provide?
A: Repeatability is ±0.3% F.S.

Q7: What is the purpose of the push-lock knob?
A: The knob can be pushed down after pressure adjustment to secure the setting and reduce accidental changes.

Q8: Can the RB Series be manifold-mounted?
A: Yes. Manifold mounting is available for centralized installation of multiple regulators.

Q9: Is a clean-room-compatible specification available?
A: Yes. A clean-room-compatible specification is available by custom order.

Q10: What applications is the RB Series suitable for?
A: It is suitable for buffers, balancers, press control, rolling equipment, tension control, and compact automation systems requiring good flow characteristics.
