Inside the Design of a Double Union Ball Valve
The Double Union Ball Valve is recognized for its modular structure that enables easy maintenance without pipe cutting or system interruption. This design offers clear advantages for heating, cooling, and plumbing systems where efficiency and access matter.

The valve operates with a precision-machined ball housed inside a durable body. When the handle turns 90 degrees, the ball’s bore aligns with the pipe to allow flow or rotates perpendicular to block it. The sealing system ensures tight closure and prevents backflow even under pressure variations.
ZHEJIANG PENGBANG TUBE INDUSTRY CO., LTD. integrates advanced machining technologies into production to achieve dimensional accuracy. Each part—from the unions to the ball stem—is produced to meet strict tolerances, ensuring smooth installation and steady performance.
The materials used are chosen for their resilience against corrosion and wear. Brass, stainless steel, and engineering plastics are commonly used to maintain both mechanical strength and chemical resistance. The company also focuses on ease of handling during installation, providing threaded or socket options that match various system designs.
In heating applications, this valve supports balanced water circulation by offering low resistance and reliable control. Its compact form suits limited-space installations while maintaining strong flow capacity. Regular inspection and replacement are straightforward, which keeps system downtime minimal.
Beyond standard production, ZHEJIANG PENGBANG TUBE INDUSTRY CO., LTD. offers customized valve solutions based on project requirements. Each product reflects a balance of functionality, durability, and craftsmanship. The Double Union Ball Valve remains one of the most practical examples of precision meeting performance in the company’s product range.
