Comprehensive Solution For Steam And Heat System
1. The valve body adopts the German coated sand casting technology, which greatly improves the surface finish and mechanical properties of the valve body, reduces the appearance of pores, blisters and cracks, and enhances the tensile strength of the casting.
2. Detachable valve seat, the valve seat can be replaced independently, and the maintenance is more convenient!
3. The double seal design (bellows + packing) completely solves the leakage of the valve stem caused by the friction between the valve stem and the packing.
4. Super long metal bellows, longer service life and safer.
5. All bellows are 100% helium tested, and all valves are 100% standard tested to ensure zero leakage.
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:
