Bellows globe valve
The Bellows Globe Valve is a high-performance industrial valve designed for reliable shut-off and flow regulation while providing zero-leakage protection for hazardous, toxic, and high-purity media. It adopts a double sealing structure with a metal bellows seal and packing backup system, effectively preventing stem leakage and ensuring long-term safe operation.
Bellows globe valve
Featuring excellent corrosion resistance, high-temperature capability, and outstanding sealing performance, the bellows globe valve is widely used in industries where environmental protection and operational safety are critical. The bellows design eliminates fugitive emissions caused by traditional stem packing wear, making it an ideal solution for demanding process applications.
We provide professional OEM and customization services, including customized valve sizes, pressure ratings, connection standards (ANSI, DIN, JIS, GB, etc.), body and trim material selection, bellows material customization, sealing structure design, actuator configuration, surface treatment, logo marking, and special engineering solutions according to customer requirements.
Our products are manufactured under strict quality control systems and comply with international valve industry standards. We provide complete valve industry certifications and inspection documents, including material certificates, pressure test reports, bellows testing reports, dimensional inspection reports, and quality assurance documentation to ensure reliable performance for global customers.
