Description
Prevost Conex Male Flow Regulator with Adjusting Screw (Control Out)
The Industry Standard for Precision Cylinder Speed Control
The Prevost Conex Male Flow Regulator with Adjusting Screw is a high-performance pneumatic valve designed to regulate the speed of air cylinders and actuators. This “Control Out” (Meter-Out) version is the industry-standard configuration for speed regulation. It controls the flow of air as it exhausts from the cylinder, providing a “cushioning” effect that results in smooth, stable, and chatter-free movement.
This model features a recessed slotted adjusting screw instead of a knob, making it ideal for low-profile installations and “set-and-forget” applications where tamper resistance is required.
Key Features
- “Control Out” (Meter-Out) Logic: This regulator allows air to enter the cylinder freely at full speed but restricts the air as it exits. This back-pressure provides superior control over the piston, preventing the “jumpy” motion common in unregulated pneumatic systems.
- Tamper-Resistant Adjustment: The recessed flat-head screw requires a tool for adjustment. This prevents accidental changes to the machine’s cycle speed by operators, ensuring consistent production quality and safety.
- Ultra-Low Profile 90° Elbow: Without a protruding adjustment knob, this fitting is perfect for dense manifolds, robotic arms, and tight control cabinets where clearance is limited.
- 360° Swivel Body: The valve body can be rotated fully around the nickel-plated brass threaded base after installation.1 This allows you to position the tubing exit at the perfect angle while keeping the adjustment screw accessible.
- Instantaneous “Grip” Technology: The outlet port features Prevost’s signature stainless steel gripping ring. Simply push the technical tubing (PU, PA, or PE) in for an immediate, vibration-proof, and airtight seal.

Why Choose Meter-Out Control?
In almost all double-acting cylinder applications, Meter-Out (Control Out) is the preferred method of speed control. Because air is compressible, simply limiting the air entering a cylinder often results in the piston “lunging” once it overcomes static friction. By limiting the air leaving the cylinder, the Prevost Conex Regulator creates a steady resistance that allows for micro-precision speed adjustments even under varying loads.
Ideal Applications
- Automated Assembly Lines: Setting a fixed, repeatable cycle time for stamping, pressing, or pick-and-place actuators.
- Machine Tooling: Controlling the feed rate of pneumatic slides or clamping mechanisms.
- Conveyor Systems: Regulating the speed of pneumatic gates and diverters to match line flow.
- Confined Enclosures: Installations where a knob-style regulator would interfere with cabinet doors or other components.
Installation Tip
Identify the flow direction by looking for the etched arrow or “out” marking on the polymer body. The arrow on this model will point away from the male thread toward the tubing port, indicating that it regulates the exhaust flow. To adjust, use a precision flat-head screwdriver: turn clockwise to slow the cylinder speed and counter-clockwise to increase it.
