1 1/2″ True Union Ball Valve Full Port Water Treatment Shut Off Valve
1 1/2″ true union ball valve with full port & detachable union ends, brass/SS316 body, easy disassembly for food & water pipeline maintenance.
Description
I. Basic Product Function
The 1 1/2″ true union ball valve is a pipeline shutoff device equipped with union connections at both ends. It is primarily used for isolation in purified water, food, and chemical circulation lines. The true union split‑body design enables rapid disassembly without pipe cutting, while the full‑port flow path ensures high‑volume transmission and easy maintenance—addressing the common drawback of conventional threaded ball valves that require pipe disruption for removal. This makes it particularly suitable for fluid equipment that demands frequent cleaning or servicing.

III. Core Product Advantages
-
True union structure – Independent union nuts on each end allow the valve body to be removed without cutting pipes. Cleaning or replacing components can be done without shutting down the entire pipeline.
-
Full‑port design – No bore reduction or internal obstructions, resulting in minimal pressure drop. High‑flow circulation is unrestricted, and there are no dead zones for media accumulation.
-
Dual sealing assurance – PTFE ball seats combined with corrosion‑resistant gaskets at the union faces ensure leak‑tight performance even after repeated assembly/disassembly.
-
Bi‑directional flow – No orientation restriction during installation, offering greater flexibility and reducing on‑site errors.
IV. Industry Applications and Real‑World Case
This valve is widely recognised as a specialised water treatment ball valve and is extensively used in purified water systems and food processing circulation lines.
Real‑world application case: Wuxi Green Water Resources – Chengdong Wastewater Treatment Plant (Pure Water Deep‑Treatment Workshop, Dongting Street, Xishan District, Wuxi, Jiangsu). The plant’s 1.5‑inch RO reverse‑osmosis purified water main circulation lines adopted the 1 1/2″ true union ball valve across the board. The system requires regular acid cleaning and filter element replacement. The true union construction allows the valve body to be directly detached without draining or cutting the pipe, drastically shortening maintenance downtime. Meanwhile, the full‑port flow path ensures stable circulation flow with no particle retention. After three years of continuous service, no leakage or flow degradation has been observed, making this valve a standard component in the plant’s purified water system.
V. Selection Guidance
-
For civil purified water systems, the brass version is recommended.
-
For food‑grade or mildly corrosive chemical services, prefer the stainless steel true union ball valve.
-
For pipelines subject to frequent disassembly and maintenance, the full‑port true union ball valve is the optimal choice.
