Import Bellows Valve — Buy in Bulk from Supplier in China

The bellows valve from ZHEJIANG Kojo Valve Co., Ltd is engineered for high-performance applications requiring strict leakage prevention. It is rated for Class 150 to 600Lb, covering a broad spectrum of pressure requirements in industrial systems. The valve employs bellows seal technology to eliminate stem leakage, a critical advantage in environments where fluid containment and system integrity are paramount.

The valve body and bonnet are typically constructed from carbon steel, stainless steel, or alloy steel, depending on the pressure class and media compatibility. The bellows, often made of stainless steel 316L for enhanced corrosion resistance, provide a hermetic seal between the stem and bonnet. Standard end connections include flanged, threaded, or socket weld, with dimensions conforming to ASME B16.5 or B16.11 for seamless integration into existing pipelines.

This valve is widely used in oil and gas, water treatment, and chemical processing industries, where reliable performance under high pressure and temperature is essential. Buyers should specify the exact pressure class, material grade, and end connection type to match their system requirements. The supplier’s location in Wenzhou, Zhejiang, offers logistical advantages for shipping from ports such as Ningbo or Shanghai.
