1. Fluid flow properties
Stainless steel ball valves use a spherical spool design, which makes it smoother in the switching process, not only easy to operate, but also able to achieve full opening or closing of the fluid. In contrast, the spool-seat design of ordinary valves in the switching process may be subject to the resistance of the fluid medium, resulting in an increase in the operating torque, fluid flow performance is also affected to some extent.
2. Sealing performance
Stainless steel ball valve sealing surface width, and spherical spool in the sealing force uniform, which makes it excellent sealing performance. The ordinary valve spool - seat sealing design after a long time of use may be due to wear and tear of the valve seat leading to a decline in sealing performance, or because of temperature changes leading to thermal expansion and contraction, affecting the sealing effect.
3. Corrosion resistance
Stainless steel ball valves are made of stainless steel, with excellent corrosion resistance. While ordinary valves are usually made of carbon steel or cast iron, in the face of corrosive media are prone to corrosion, shorter service life.
4. Durability
Stainless steel ball valve structure is simple, and in the switching process, the contact area between the spool and the valve seat is small, so there is little wear and tear, long service life. The ordinary valve due to the complex structure, and the spool - seat sealing surface is easy to wear, need frequent maintenance or replacement.
5. Energy saving
Stainless steel ball valves in the adjustment of fluid flow, can quickly reach the required flow, compared with ordinary valves more energy-saving.
