Prevost Conex Male Regulator With Adjusting Screw (Bi-Directional)

Description

Prevost Conex Male Regulator with Adjusting Screw (Bi-Directional)

Low-Profile, Symmetrical Control for Precision Pneumatics

The Prevost Conex Male Regulator with Adjusting Screw (Bi-Directional) is a high-precision flow control valve designed for applications that require equalized airflow restriction in both directions. Unlike standard “one-way” regulators, this bi-directional model regulates air moving from the thread to the tube and from the tube back to the thread simultaneously.

Featuring a recessed, slotted adjusting screw, this regulator is the professional’s choice for “set-and-forget” applications where space is limited and tamper resistance is required to maintain system consistency.

Key Features

• Symmetrical Bi-Directional Regulation: This valve utilizes a precision needle without an internal bypass check valve. This ensures that the airflow is restricted equally regardless of the flow direction, making it ideal for air motors, tools, and balanced pressure circuits.
• Tamper-Resistant Adjusting Screw: The low-profile, slotted screw design requires a flat-head screwdriver for adjustment. This prevents accidental changes to the flow rate and discourages unauthorized “fiddling” by operators on the production floor.
• Ultra-Compact 90° Elbow: The slim profile of the elbow body allows for high-density installation in tight control cabinets or directly onto compact actuators where a protruding knob would cause interference.
• 360° Swivel Body: The valve body can be rotated fully around the nickel-plated brass threaded base after installation. This allows you to orient the tubing exit perfectly while keeping the adjustment screw accessible for maintenance.
• Instantaneous “Grip” Technology: The outlet features the standard Conex push-in mechanism with a stainless steel gripping ring, providing a leak-free and vibration-proof connection to your PU or Nylon tubing.

The Advantage of Symmetrical Regulation

Bi-directional control is essential for specialized pneumatic logic. While most cylinders use “Meter-Out” logic, the Bi-Directional Adjusting Screw Regulator is the superior choice for:

1. Air-Driven Motors: Regulating the speed of a tool that must run at the same velocity in both forward and reverse.
2. Damping & Oscillations: Adding “resistance” to a circuit to smooth out vibrations or prevent rapid bouncing in high-speed systems.
3. Pressure Bleeding: Controlling the rate at which a reservoir or pilot line both charges and exhausts, ensuring repeatable timing cycles.

Ideal Applications

• Automated Machine Tools: Setting a fixed speed for air-driven spindles or small pneumatic grinders.
• Process Valve Timing: Coordinating the opening and closing speed of large process valves to prevent mechanical shock.
• Robotic End-of-Arm Tooling: Providing compact, lightweight speed control for miniature grippers and rotating joints.
• Safety Guards: Setting a permanent, safe operating speed for pneumatic covers that cannot be easily altered by personnel.

Installation Tip

When installing, tighten the brass hexagonal base into your port first. Once secure, swivel the polymer body to the desired angle. To adjust the flow, use a precision flat-head screwdriver. Because this is a bi-directional model, it does not have a “check valve arrow” on the body, as it restricts flow in both directions equally.
