4 Passage Rotary Union-Precision Multi Channel Fluid Transfer Solution

Description

The 4 Passage Rotary Union is a high-performance, multi-channel rotary joint specifically engineered to handle simultaneous fluid, gas, or air transfers through four independent passages. It features a cutting-edge design that sets it apart from conventional rotary unions. With four independent passages, this advanced device enables the simultaneous transfer of multiple fluids, such as hydraulic oil, coolant, air, and steam, without cross-contamination. This unique feature not only enhances the efficiency of your machinery but also reduces the need for multiple rotary unions, saving you valuable space and costs.​

Our 4-passage rotary unions are constructed using high-quality materials, including stainless steel, carbon steel, and alloy steel, to ensure exceptional durability and resistance to corrosion, wear, and high temperatures. The precision-machined components and tight tolerances guarantee smooth rotation and leak-free operation, even under the most demanding conditions. Additionally, the union is equipped with advanced sealing technologies, such as mechanical seals and lip seals, to provide reliable and long-lasting performance.​

FAQ

What is a 4-passage rotary union?

It is a mechanical device that allows the transfer of multiple fluids (such as air, water, oil, or hydraulic fluid) through four independent passages while rotating. This design is essential for applications requiring simultaneous fluid delivery without cross-contamination.

What applications are suitable for 4-passage rotary unions?

These rotary unions are commonly used in various applications, including CNC machining, robotics, hydraulic systems, and any industrial process requiring the transfer of multiple fluids simultaneously. They are ideal for clamping and unclamping operations, spindle cooling, and powering pneumatic tools.

What are the key features of these kinds of unions?

Multiple Independent Passages: Allows for different fluids to be transferred without mixing.
High Pressure and Speed Ratings: Many models can handle pressures up to 7,500 PSI and rotational speeds exceeding 10,000 RPM.
Robust Sealing Technology: Designed to prevent leakage and prolong service life.

What maintenance is required for 4-passage rotary unions?

Regular maintenance includes inspecting seals for wear, checking for leaks, and ensuring that the operating conditions (pressure and temperature) remain within specified limits. Lubrication may also be necessary depending on the design.

What is the pressure rating for these typical unions?

Pressure ratings can vary widely based on the model and manufacturer. Many standard models can handle pressures from 40 bar (580 PSI) up to 515 bar (7,500 PSI), making them suitable for high-pressure applications.

What materials are commonly used in the construction of the unions?

Carbon Steel: Often used for general-purpose applications.
Stainless Steel: Preferred for corrosive environments or where hygiene is critical.
Aluminum: Used in lightweight applications where weight savings are essential.
