Pipeline operators often need a valve that can provide reliable shut-off performance while keeping installation and maintenance simple. Conventional valves may require extensive pipe disassembly when servicing or replacing the valve, increasing downtime and labor costs.
Our UPVC True Union Ball Valve is designed to solve this problem with a practical double-union structure. The valve can be isolated and removed from the pipeline for inspection, maintenance, or replacement without dismantling the entire piping system.
Made from corrosion-resistant UPVC, the valve is particularly suitable for water and many chemical fluid applications where corrosion resistance, lightweight construction, and reliable flow control are important.
The compact full-port design provides efficient fluid passage, while the quarter-turn handle enables quick opening and closing. Different connection types, seal materials, sizes, and pressure ratings can be supplied according to project requirements.

UPVC ball valves are widely used in water treatment and fluid distribution systems where corrosion resistance and reliable shut-off are required.
The lightweight structure and easy operation make UPVC True Union Ball Valves suitable for irrigation pipelines, agricultural water systems, and water distribution equipment.
UPVC construction provides a practical solution for swimming pool circulation, filtration, water treatment, and aquaculture piping systems.
For compatible chemical media, UPVC offers corrosion resistance and low-maintenance operation compared with many traditional metal valve options. Seal and material compatibility should always be confirmed for the specific medium and operating conditions.
The compact structure and convenient maintenance design make the valve suitable for reverse osmosis, water purification, and related fluid handling equipment.
The biggest advantage of a true union design is serviceability.
When maintenance is required, the valve body can be removed from between the union connections without completely dismantling the surrounding pipeline. This can reduce maintenance work and help minimize system downtime.
For industrial and commercial piping projects where maintenance accessibility is important, this design provides a practical advantage over conventional fixed-body valves.
Different projects require different connection methods. Depending on the valve model, we can provide:
Please specify the required pipe standard and connection type when requesting a quotation.
Different fluids and temperatures require different sealing materials.
EPDM: Commonly used for water and many general fluid applications.
FKM: Suitable for applications requiring enhanced chemical and temperature resistance.
PTFE: Commonly used as a valve seat material where low friction and chemical resistance are important.
The final seal and seat combination should be selected according to the actual medium, temperature, pressure, and chemical compatibility.
A:A UPVC True Union Ball Valve is a plastic ball valve with union connections on both sides. The union design allows the valve body to be removed for maintenance or replacement without dismantling the complete pipeline.
A:A standard UPVC ball valve may have fixed connections, while a true union ball valve uses removable union connections. This makes the true union design more convenient for maintenance, replacement, and equipment servicing.
A:Common sizes range from 1/2 inch to 4 inches (DN15–DN100), although the actual range depends on the specific product series. Customized sizes may also be available for OEM projects.
A:Common product configurations are available in PN10 or PN16, depending on size and model. The exact pressure rating should be confirmed from the product datasheet before ordering.
A:UPVC provides good resistance to corrosion and is widely used in water treatment, irrigation, swimming pool, and compatible chemical fluid applications. The valve material must be checked against the specific medium before use.
A:Common sealing options include EPDM and FKM, while PTFE is commonly used for the valve seat. The appropriate material depends on the fluid, temperature, pressure, and chemical compatibility requirements.
A:Yes. Depending on the project, customization may include size, connection type, seal material, color, packaging, labeling, and other OEM requirements.
A:Yes. Samples can be arranged for product evaluation, while bulk orders can be supplied directly from the factory. Contact us with your required size, quantity, connection type, pressure rating, and destination market for a quotation.
