350 Series control valves are heavy-duty globe style valves featuring expanded end connections and large internal cavities. Designed to keep valve outlet velocities within practical limits, these high-capacity valves are well suited for service applications where oversized piping is used to limit flow velocities.
These control valves are cage guided, single port valves that can be used for both throttling or on/off process control. Functioning especially well for noise reduction requirements, 350 Series valves offer superior performance.
