Advantages of Union Ball Valve
Safety and durability
The brass material exhibits excellent corrosion resistance, while the ptfe seals are wear-resistant and high-temperature resistant, ensuring minimal leakage over long-term use. The union structure allows for quick replacement of the valve core, reducing maintenance costs (as traditional one-piece valves require complete replacement).
Flexible adaptability
Available in either angle-type or straight-through designs, it meets the needs of pipeline direction changes or installation in confined spaces. It is compatible with a variety of pipeline systems (including plumbing, gas, and industrial fluid systems), demonstrating strong versatility.
Operational convenience
A 90° rotating handle enables rapid opening and closing with minimal operating torque, supporting frequent switching operations. The union design eliminates the need for specialized tools, simplifying the installation process.
Specification of Union Ball Valve
Features of Union Ball Valve
Angular design: The valve body adopts a 90-degree angular structure, with the inlet and outlet ports arranged at right angles to each other. This design is suitable for applications where pipeline space is limited or where a change in fluid direction is required. It optimizes pipeline layout, reduces the need for elbows, and lowers system resistance.
Union connection: Both ends of the valve utilize union connections (either ferrule-type or threaded), enabling quick assembly and disassembly for easy maintenance and replacement. Compared to traditional flanged or welded connections, the union design significantly reduces downtime, making it particularly suitable for applications requiring frequent maintenance.
Ball and seat: The valve employs a floating ball structure, where the ball and seat achieve sealing through spring preloading, making it suitable for medium- to low-pressure conditions. The seat material is typically ptfe, ppl, or a metal hard seal, which can be selected based on the characteristics of the medium.
Sealing performance: A double-sided sealing design ensures zero leakage in both the fully open and fully closed states of the valve, complying with international standards (such as api 607 fire test).
Types of Union Ball Valve
Angle union ball valve
In central air conditioning and heating systems, it is utilized for flow regulation of chilled water, hot water, and refrigerated water. The angular design optimizes pipeline layout, minimizing space usage.
MF union ball valve
The MF union ball valve incorporates a union connection method, facilitating easy installation. It is suitable for pipeline systems that require frequent disassembly or maintenance.
FF union ball valve
It is specifically designed for heating systems, central air conditioning, and industrial fluid control systems. Characterized by its high sealing performance, flexible installation capabilities, corrosion resistance, and intelligent compatibility, the valve holds a prominent advantage within the industry.
