Smc Pneumatics AS2201F-N02-04SA Flow Control Valve

Product Description

The SMC PNEUMATICS AS2201F-N02-04SA is a speed flow control valve designed to regulate airflow in pneumatic circuits. It combines an elbow-style tube fitting with an integrated flow control mechanism, allowing technicians to meter air in one direction while permitting free flow in the other. The valve accepts a 4MM tube and connects to a 1/4 NPT port, making it a compact, single-assembly solution for speed control on pneumatic actuators and cylinders. It is installed by pneumatic system technicians in industrial, automation, and manufacturing environments.

This valve is suited for applications where precise cylinder speed control is required at the port level. The elbow configuration allows for routing tubing perpendicular to the actuator port, which is useful in tight panel or manifold installations. It is commonly found in automated assembly lines, material handling equipment, and light industrial machinery where controlled actuator movement is critical to process timing and safety.

Key Features

• Integrated elbow tube fitting and flow control in a single compact body
• 1/4 NPT male thread for direct port mounting on actuators or valves
• 4MM push-to-connect tube fitting for tool-free tube installation and removal
• Elbow orientation routes tubing perpendicular to the port for space-constrained layouts
• Needle valve adjustment allows repeatable, fine-tuned airflow metering

Compatibility

Designed as an OEM-style flow control fitting for pneumatic systems with 1/4 NPT actuator or valve ports and 4MM OD tubing.

Installation Notes

Installation is performed by pneumatic system technicians or automation maintenance personnel. Depressurize and lock out the pneumatic circuit before installing or adjusting this valve. Apply appropriate thread sealant to the NPT threads per standard practice, and do not overtighten, as NPT fittings are tapered and can crack valve bodies if forced. Adjust the needle valve gradually after pressurizing the circuit to dial in the desired actuator speed.
