Prevost Conex Male Thread Flow Regulator One Way

Description

Prevost Conex Male Thread Flow Regulator (One Way)

Integrated Flow Control for Direct Actuator Mounting

The Prevost Conex Male Thread Flow Regulator is a precision needle valve designed to control the operating speed of pneumatic cylinders and actuators. This “One Way” (unidirectional) model allows for metered airflow in one direction while providing unrestricted “free flow” in the opposite direction via an internal bypass check valve.

Available in both Meter-In and Meter-Out configurations, this regulator threads directly into the supply port of your component, providing a compact and accessible adjustment point for fine-tuning machine performance.

Key Features

• Unidirectional Precision Control: Features a high-sensitivity needle valve that allows for micro-adjustments to airflow. This ensures smooth, consistent actuator movement and eliminates the “jerky” motion often found in unregulated systems.
• Instantaneous “Grip” Technology: The outlet port is equipped with Prevost’s signature stainless steel gripping ring. Simply push the technical tubing (PU, PA, or PE) into the fitting for a secure, airtight, and vibration-resistant seal.
• 360° Swivel Body: The 90-degree elbow body can be rotated fully around the threaded base after installation. This allows you to orient the tubing exit and the adjustment point in the most convenient direction for your layout.
• Rugged Hybrid Construction: Combines a high-strength nickel-plated brass threaded base for mechanical durability with a high-impact technical polymer body that resists corrosion and common industrial oils.
• Visual Flow Indication: Most models feature a clear arrow or symbol etched into the body to indicate the direction of regulated flow, simplifying installation and troubleshooting for maintenance teams.

Optimizing Actuator Performance

Choosing the right flow regulator configuration is critical for system efficiency:

• Meter-Out (Control Out): Regulates air as it exhausts from the cylinder. This is the industry standard for double-acting cylinders as it provides superior control by “cushioning” the piston against the exhausting air.
• Meter-In (Control In): Regulates air as it enters the cylinder. This is typically used for single-acting (spring return) cylinders or specific timing circuits where the supply volume must be restricted.

Ideal Applications

• Automated Production Lines: Controlling the extension and retraction speeds of air cylinders for stamping, sorting, or assembly.
• Packaging Machinery: Synchronizing the movement of pneumatic gates and cutters with conveyor speeds.
• Safety Guards: Regulating the closing speed of pneumatic doors to ensure operator safety.
• Tooling Fixtures: Slowing the descent of pneumatic clamps to prevent damage to delicate workpieces.

Installation Tip

For a 100% leak-free connection, ensure your tubing is cut perfectly square using a dedicated tube cutter. When threading the regulator into your actuator port, do not over-torque; the nickel-plated brass base is designed to seal effectively with standard force. Once installed, use the locking nut (if equipped) to secure the needle position and prevent setting drift caused by machine vibration.
