The V9000 control valve is a common and essential component in heating, temperature control, refrigeration, and the entire field of industrial fluid automation. In the use of globe straight-stroke control valves at various sites, not only is there a high demand for precision in control valve regulation but also an increasing requirement for external leak sealing, especially in scenarios demanding clean air, such as petrochemical plants and other special occasions.
Some media can pollute the ambient air (like steam and ammonia), are highly toxic (such as chlorine gas, hydrogen cyanide, and hydrogen chloride), are flammable or explosive (such as thermal oil), or are highly corrosive when exposed to air (like trichlorosilane and silicon tetrachloride), not to mention characteristics of precious metals. Any external leakage of such media can lead to product scrap, fire explosions at the site, equipment damage, personnel poisoning, and other safety incidents, resulting in shutdowns and production stops, causing significant losses to users.
Conventional control valves are prone to issues such as packing wear leading to external leaks, poor adjustment accuracy, and unreliable longevity of bellows seals.
In response to these series of hazards, the Newton research and development team conducted in-depth site visits, collected extensive operational information, tackled technical challenges, and validated their solutions with a wealth of experimental tests. The designed, manufactured, and delivered V9000 series Globe Bellows Straight-Stroke Control Valves can fully meet customer needs. V9000 series bellows control valves have the following features:
-
Long-period cycle operation of the valve stem ensures zero leakage.
-
Bellows life expectancy of over 500,000 cycles.
-
High regulation accuracy.
-
Convenient and quick on-site maintenance of the valve.
-
Rapid response time.
-
Wide operating temperature range (-196℃ to 588℃).
-
Capable of long maintenance-free periods during online operation.
-
Depending on the site's energy configuration, it can be fitted with pneumatic diaphragm actuators or electric actuators.
