Prevost Conex Tube Flow Regulator One Way

Description

Prevost Conex Tube Flow Regulator (One Way)

In-Line Precision for Remote Speed Control

The Prevost Conex Tube Flow Regulator is a high-performance, push-to-connect in-line valve designed to manage the speed of pneumatic actuators by metering airflow. Unlike standard regulators that thread directly into a cylinder port, this Tube-to-Tube union allows for flow regulation anywhere along a run of flexible tubing.

This is the ideal solution for complex machinery where the cylinders are tucked away in hard-to-reach areas, allowing you to bring the adjustment point to a more accessible and ergonomic location.

Key Features

• One-Way (Unidirectional) Regulation: This valve restricts airflow in one direction (controlled by a precision needle) while allowing “free flow” in the opposite direction via an internal bypass check valve.
• “Floatable” In-Line Design: Because it connects two sections of tubing, it can be integrated into a wire loom, cable track, or mounted to a control panel, providing “remote” speed control for buried actuators.
• Instantaneous “Grip” Technology: Both ports feature Prevost’s signature stainless steel gripping rings. Simply push your technical tubing (PU, PA, or PE) into the ports for a leak-free, vibration-resistant seal—no tools required.
• Precision Metering: The internal needle valve is designed for high-sensitivity adjustment, ensuring smooth, “chatter-free” cylinder movement even at low speeds.
• Rugged & Lightweight: Constructed from high-impact technical polymer, this regulator is naturally resistant to corrosion and common industrial oils, making it durable yet light enough to be supported by the tubing itself.

The Benefit of In-Line Regulation

In many automation setups, adjusting a cylinder’s speed is a frequent requirement for fine-tuning production cycles. The Prevost Conex In-Line Regulator eliminates the need to reach into dangerous or cramped machine interiors. By placing the regulator in an accessible spot, technicians can safely and quickly adjust stroke speeds to match changes in production requirements.

Ideal Applications

• Remote Cylinder Speed Control: Adjusting actuators located behind safety guards or deep within machine frames.
• Pneumatic Logic & Timing: Creating precise delays or “metered” air pulses in automated sequences.
• Laboratory Instrumentation: Fine-tuning air or vacuum flow in compact diagnostic equipment.
• Robotic End-Effectors: Regulating the speed of pneumatic grippers without adding weight to the robot’s “wrist.”

Installation Tip

Always check the flow direction arrow etched into the side of the polymer body. The valve will only restrict airflow moving in the direction of the arrow. To ensure a 100% seal, use a dedicated tube cutter to ensure a square cut, and push the tubing in until it seats past the internal O-ring.
