feature
1. Excellent zero leakage sealing: Adopting a unique water seal system design, a stable liquid film sealing ring is formed between the valve disc and the valve seat sealing pair by injecting clean water or softened water, achieving absolute cut-off and zero leakage sealing, especially suitable for toxic, harmful, flammable, explosive or valuable media.
2. Adapt to high pressure, high temperature, and harsh working conditions: The key components of the valve are made of high temperature resistant, erosion resistant, and corrosion-resistant materials, with high structural strength and special hardening treatment on the sealing surface, which can operate stably for a long time in high temperature, high pressure, and harsh media containing trace particles.
3. Self cleaning and safety protection: The water sealing medium can continuously flush the sealing surface while sealing to prevent scaling, crystallization, or particle deposition, and maintain the cleanliness of the sealing pair; The water seal system can also serve as an isolation barrier, effectively preventing the leakage of hazardous media and enhancing the intrinsic safety of the system.
4. Reliable operation and dual control: supports manual, electric or pneumatic drive, with excellent valve stem guidance structure and smooth movement; The water seal system can independently adjust the water pressure to form a sealing force that matches the medium pressure, ensuring reliable sealing of the valve during the opening and closing process and in the fully closed position.
5. Compact structure and easy maintenance: using standard flange connection, easy installation; The water seal chamber is designed independently of the medium flow channel, and there is no need to remove the valve from the pipeline as a whole when inspecting, injecting water, or replacing sealing components. Maintenance is simple and does not affect pipeline operation.
6. System integration and intelligent monitoring: The water seal pressure can be connected to the instrument system for real-time monitoring and alarm; Combined with intelligent actuators, remote monitoring and automatic interlocking control of valve status and water seal pressure can be achieved, which is easy to integrate into the automation management platform and improves process safety and reliability.
