Prevost Conex Male Flow Regulator With Knob (Control Out)

Description

Prevost Conex Male Flow Regulator with Knob (Control Out)

Precision Manual Speed Control for Pneumatic Actuators

The Prevost Conex Male Flow Regulator with Knob is a high-performance unidirectional valve designed to provide precise, tool-free adjustment of pneumatic cylinder speeds. This “Control Out” (also known as Meter-Out) configuration is the gold standard for pneumatic regulation. It controls the airflow as it exhausts from the actuator, creating a stabilizing back-pressure that ensures smooth, consistent movement without the “jerky” motion or lunging typical of unregulated systems.

Equipped with an ergonomic adjustment knob, this regulator allows operators to fine-tune machine cycles on the fly, making it ideal for dynamic production environments.

Key Features

• “Control Out” (Meter-Out) Logic: This regulator allows air to enter the cylinder freely but restricts the air as it leaves. By metering the exhaust, the piston is “cushioned” by the air remaining in the cylinder, providing superior control even under varying loads.
• Tool-Free Adjustment Knob: The textured, ergonomic knob allows for instant manual tuning. No hex keys or screwdrivers are required to dial in the perfect speed, significantly reducing setup and maintenance time.
• 360° Swivel Elbow Body: The 90-degree body rotates fully around the nickel-plated brass threaded base. This allows you to orient the tubing inlet and the adjustment knob in the most accessible direction, regardless of the thread’s final seated position.
• Instantaneous “Grip” Technology: The intake port features Prevost’s signature stainless steel gripping ring. Simply push the technical tubing (PU, PA, or PE) in for a secure, airtight, and vibration-proof seal.
• Robust Hybrid Construction: Combines a high-strength nickel-plated brass threaded base for mechanical durability with a high-impact technical polymer body resistant to corrosion and industrial oils.

Optimizing Machine Cycle Times

In professional automation, the Prevost Conex Flow Regulator is the key to balancing speed and longevity. By using Meter-Out regulation, you prevent the internal piston from slamming against the cylinder end-caps at high speeds. This not only protects the actuator from premature wear but also reduces the vibration and noise of the overall machine. The manual knob is particularly useful for:

1. Fine-Tuning Synchronization: Aligning the speeds of two parallel cylinders so they move in perfect unison.
2. On-the-Fly Optimization: Adjusting cycle speeds to match different product weights or line speeds during a shift.

Ideal Applications

• Packaging & Sorting: Regulating the speed of pneumatic pushers, gates, and diverters.
• Material Handling: Controlling the extension and retraction of air-driven clamping and lifting units.
• Automated Assembly: Fine-tuning the descent speed of pneumatic presses or SMT pick-and-place heads.
• Prototyping: Providing an easy-to-adjust interface for developing new pneumatic logic circuits.

Installation Tip

Verify the flow direction by looking for the etched arrow on the side of the polymer body. For a “Control Out” regulator, the arrow points away from the male thread toward the tubing port, indicating that it regulates the air exiting the device. For a permanent setting, hand-tighten the integrated locking nut (if applicable) to prevent the knob from turning due to machine vibration.
