Camozzi Automation RFU-444-04 Flow Control Valve

Camozzi RFU-444-04 is an inline, unidirectional flow-control valve in Camozzi’s RFU series that meters air flow in one direction to regulate pneumatic actuator speed. The RFU-444-04 variant provides a flow-control bore up to Ø 4 mm, enabling precise metering in compact pneumatic circuits. Designed for inline installation, the RFU family supports unidirectional flow control to allow easy adjustment of actuator speed while the opposite flow path remains unrestricted. This model is commonly used to throttle the supply or exhaust path to a cylinder, enabling controlled start-up and smoother operation in automation tasks such as clamping, gripping, and other pneumatic positioning actions. The RFU-444-04 is documented by Camozzi and is available through the company’s official catalog and online store, reflecting Camozzi Automation S.p.A.’s emphasis on compact, reliable flow control for small-bore lines.
