German standard bellows gate valve
The German standard bellows gate valve features a welded stainless steel bellows seal that eliminates stem leakage and reduces maintenance requirements. Manufactured according to DIN and EN standards, it provides excellent sealing performance, environmental protection, and operational safety for steam, thermal oil, chemicals, and high-temperature industrial process systems.
German standard bellows gate valve
The German Standard Bellows Gate Valve is designed to meet stringent DIN and EN requirements for leak-free operation and environmental protection. The valve incorporates a precision-welded stainless steel bellows assembly that forms a permanent seal between the process media and the atmosphere, preventing fugitive emissions and stem leakage.
A secondary graphite packing seal provides additional safety protection, ensuring long-term reliability under demanding operating conditions. The full-port gate design minimizes pressure loss while delivering dependable shut-off performance.
Manufactured from high-quality cast steel, stainless steel, and alloy steel materials, German standard bellows gate valves are widely used in steam systems, chemical processing plants, thermal power stations, pharmaceutical facilities, and district heating networks.
As a professional industrial valve manufacturer, we provide comprehensive OEM and ODM solutions.
All German standard bellows gate valves are manufactured and tested according to international and European standards.
