Prevost Conex Male Flow Regulator (Inlet Male / Outlet Tube)

Description

Prevost Conex Male Flow Regulator (Inlet Male / Outlet Tube)

Unidirectional Precision for Inline Airflow Management

The Prevost Conex One-Way Flow Regulator is a high-performance control valve designed to manage the velocity of compressed air within a specific branch of your pneumatic system. This Inlet Male to Outlet Tube configuration is engineered to thread directly into a supply port (such as a manifold or valve) and regulate the air flowing out toward the connected tubing.

By restricting flow in one direction while allowing free flow in the opposite direction, this regulator provides the precise “metering” required for delicate pneumatic timing and actuator speed control.¹

Key Features

• One-Way (Unidirectional) Regulation: This valve features an internal check valve mechanism. It restricts airflow moving from the Male Thread (Inlet) to the Push-in Tube (Outlet), while allowing air returning from the tube to pass through freely.
• Precision Needle Adjustment: Equipped with a fine-thread adjustment screw (or knob), allowing for micro-adjustments to the air volume. This ensures smooth, repeatable, and “chatter-free” operation of pneumatic cylinders.
• Compact Elbow Design: The 90 degree geometry allows for a low-profile installation, keeping the adjustment point accessible while saving space in crowded machinery or control cabinets.
• 360° Swivel Body: Even after the threaded base is tightened into the port, the polymer body can be rotated to the ideal orientation for tubing alignment and adjustment access.
• Instantaneous “Grip” Technology: The outlet port uses a high-grade stainless steel gripping ring. Simply push your technical tubing (PU, PA, or PE) into the fitting for a secure, airtight, and vibration-resistant connection.

The “Control In” Advantage

This specific configuration (Inlet Male / Outlet Tube) is often used as a Meter-In controller. When threaded into a valve manifold, it regulates the speed at which air enters the supply line. This is essential for:

1. Single-Acting Cylinders: Controlling the extension speed of spring-return actuators.
2. Pressure Buffering: Preventing “pressure spikes” when a valve is first opened, protecting sensitive downstream instruments.
3. Timing Circuits: Delaying the signal reaching a pilot-operated valve.

Ideal Applications

• Direct Manifold Mounting: Regulating individual air lines directly from a central supply block.
• Process Automation: Fine-tuning the speed of air-driven conveyors or sorting gates.
• Tool Protection: Limiting the air volume to small air-powered spindles or sensors to prevent over-speeding.
• Pneumatic Logic: Creating precise time-delay functions in air-only control systems.

Installation Tip

Identify the flow direction indicated by the arrow etched on the side of the fitting body. For this model, the restricted flow moves from the threads to the tube. To lock your setting, many models include a locking nut on the adjustment needle to prevent “drift” caused by system vibration.
