Industrial Bellows Sealed Globe Valve Supplier
A bellows sealed globe valve is a special type of globe valve equipped with a metal bellows sealing system to prevent leakage from the stem area. Compared with conventional packed globe valves, bellows sealed globe valves provide zero leakage or extremely low leakage performance, making them ideal for hazardous, toxic, flammable, expensive, or high purity media.
As a professional bellows sealed globe valve manufacturer, Wenzhou Zoncic Machinery Technology Co., Ltd supplies high quality bellows sealed valves for chemical processing, steam systems, thermal oil, pharmaceutical, gas service, and industrial pipeline applications. Our bellows sealed globe valve products are available in WCB, stainless steel, alloy steel, and special materials, and can be manufactured according to API, ASME, DIN, JIS, and project-specific standards.
- ✔ Zero leakage metal bellows sealing design
- ✔ Ideal for hazardous, toxic, and high purity media
- ✔ Reliable shut-off and stable throttling performance
- ✔ Long service life with reduced maintenance requirements
