Double-Union Ball Valve
The double-union ball valve is a type of polymer valve widely used in polyethylene pipeline systems. This multi‑connection double‑union valve is designed for opening and closing the flow of fluids in irrigation networks. The UPVC double‑union ball valve contains a specially engineered internal ball that rotates to open or close the passage, thereby controlling the fluid flow within the pipeline.
Technical Specifications of UPVC Double-Union Ball Valve
The double-union ball valve features minimal pressure loss and excellent resistance to sunlight and UV radiation. Each unit undergoes 100% functional and quality testing before leaving the factory, ensuring reliable performance in various applications.
The technical specifications of the UPVC double-union ball valve are as follows:
- Nominal pressure: 6 bar
- Material: Polymer
- Available size: 1 1/2″ × 1 1/2″
- Connection type: Double-union
- Valve type: Ball valve (ball-operated open/close mechanism)
- Handle type: Short handle
- Suitable for installation in both horizontal and vertical positions
- Flow and pressure adjustment by opening or closing the valve
- No need for complex maintenance or servicing
- High resistance to chemical corrosion and sunlight
- Resistant to scaling and deposits
- High durability and structural strength
Applications of Double-Union Ball Valve
The double-union ball valve is also commonly known as a double-threaded or double‑male‑thread ball valve. This polymer multi‑connection valve operates as a 90‑degree ball valve, where rotating the handle opens or closes the fluid flow.
For systems that require rapid switching between open and closed positions, the double‑union ball valve is an ideal choice due to its fast operating mechanism, making it highly suitable for irrigation applications.
