More Details

380 Series control valves are cage guided control valves with balanced plugs. Model 380 control valves are capable of Class V shutoff at process temperatures below 450°F (232°C). Model 381 control valves are well suited for general applications that do not require tight shutoff.  

These valves are designed for high pressure applications and are used in oil and gas, chemical/ petro-chemical, power generation, water distribution and/or treatment, and general industries.
