When to use metal seated ball valve?
The seat of a metal seated ball valve is often stellite, stainless steel, or tungsten carbide instead of soft seat material like ptfe, peek, nylon, teflon, and devlon. These metal to metal seat ball valves are especially applicable for:
-Media with high temperature
-Media with solid particulate for high abrasion
-Media with severe condition, like high erosion and corrosion
-Media with high viscosity like heavy oil
Our Main Product Range
Dervos main products include ball valves, butterfly valves, check valves, gate valves, globe valves, and plug valves in different materials, sizes, standards and types as per clients’ requests.
