Prevost Conex Unequal Valve Three-Ways (Tube-to-Tube)
Integrated Flow Control & Modular Reduction in a Single Junction
The Prevost Conex Unequal Valve Three-Ways is a high-performance manual control fitting that combines three essential functions into one compact component: 3-way air distribution, manual shut-off, and line-size reduction. This valve allows you to take a primary air supply and split it into two separate branch lines of a smaller diameter, while providing the ability to manually isolate the downstream flow.
By eliminating the need for separate reducers and shut-off valves, this “all-in-one” solution reduces the number of potential leak points and significantly simplifies your pneumatic architecture.
Key Features
- Unequal Port Configuration: Features a larger “Inlet” port and two smaller “Outlet” ports. This is the ideal solution for branching off a main supply line (e.g., 10mm) to feed smaller actuator or sensor lines (e.g., 6mm or 8mm).
- Manual 3-Way Control: Equipped with a high-visibility ergonomic lever. With a simple 90 degree turn, you can instantly shut off or open the airflow to the downstream branches, making it perfect for localized maintenance or selective tool operation.
- Instantaneous “Grip” Technology: All three ports utilize Prevost’s signature stainless steel gripping rings. Simply push the technical tubing (PU, PA, or PE) into the ports for an immediate, vibration-proof, and airtight seal.
- Streamlined “Y” Geometry: The internal flow path is designed for high efficiency. The “Y” shape allows air to transition from the large inlet to the smaller outlets with minimal turbulence and optimal pressure retention.
- Rugged Technical Polymer: Constructed from high-impact, corrosion-resistant polymer, this valve is lightweight enough to be supported by the tubing itself while being durable enough for harsh industrial environments.

The Efficient Choice for Modular Machinery
The Prevost Conex Unequal Valve is a “system-level” problem solver. In many automated setups, a large main line provides the volume required for the machine, but individual sections only require small-diameter tubing. This valve allows you to:
- Reduce and Distribute: Step down the line size and split the flow simultaneously.
- Safety Isolation: Manually “lock out” a specific section of the machine for repair without depressurizing the entire plant air system.
- Energy Savings: Easily shut off air to unused branches or tools at the end of a shift to prevent costly compressor cycles due to downstream leaks.
Ideal Applications
- Workstation Branching: Splitting a main overhead drop into two smaller lines for individual pneumatic tools.
- Control Cabinet Manifolds: Serving as a master shut-off for a bank of smaller solenoid valves or sensors.
- Maintenance Drops: Providing a localized isolation point for air-driven machinery.
- Robotic Tooling: Distributing air from the robot’s primary supply to multiple smaller grippers or vacuum cups.
Installation Tip
For a 100% leak-free seal, ensure all tubing ends are cut square using a dedicated tube cutter. When inserting the tubing, push firmly until it seats past the internal O-ring. Because this is an unequal valve, double-check that your inlet tube matches the larger port and your branch tubes match the two smaller outlets.
