360 Series
General Purpose, Highly Configurable Control Valve
1/2 to 8 inch NPS (15 to 200mm DN)
Globe and Angle Body Styles
RF | RTJ | BWE | SWE | FNPT Available End Connections
ASME B16.34 Class 150 to 600 Pressure Rating
ANSI/FCI 70.2 and IEC 60534-4 Class II to VI Shutoff
360 Series control valves are heavy-duty globe and angle style valves perfect for general service or severe service applications. These valves are used in a variety of demanding environments, including oil and gas, chemical/ petro-chemical, power generation, water distribution and/or treatment, and general industries.
The standard actuator for 360 Series valves is a Dyna-Flo Model DFC (fail closed) or DFO (fail open) linear actuator. These heavy-duty actuators are spring and diaphragm style, and can be used for throttling or on-off service, with or without a valve positioner.
Applications
Oil and gas, chemical/petro-chemical, power generation, water distribution and/or treatment, and general industries.

350 Series
A severe service control valve with larger internal cavities for noise and cavitation control.
- 6 to 12 inch NPS (150 to 300mm DN)
- Globe Body Style
- RF | RTJ | BWE Available End Connections
- ASME B16.34 Class 150 to 600 Pressure Rating
- ANSI/FCI 70.2 and IEC 60534-4 Class II to V Shutoff
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.
Applications
Well suited for service applications where oversized piping is used to limit flow velocities

370 Series
Larger version of the 360 Series, which is our most versatile, general purpose control valve series.
- 12 inch NPS (300mm DN) valve body with 12, 14 or 16 inch flanges
- Globe Body Style
- RF and RTJ Available End Connections
- ASME B16.34 Class 150 to 600 Pressure Rating
- ANSI/FCI 70.2 and IEC 60534-4 Class III to V Shutoff
370 Series control valves are heavy-duty globe style control valves designed to be larger versions of our 360 Series control valves. These valves are used in a variety of demanding environments, including oil and gas, chemical/ petro-chemical, power generation, water distribution and/or treatment, and general industries.
These valves are balanced, cage guided, single port valves that can be used for either throttling or on/off control of liquids or gasses.
Applications
Used in a variety of demanding environments, including oil and gas, chemical/ petro-chemical, power generation, water distribution and/or treatment, and general industries.

380 Series
Cage guided control valves designed for high pressure applications.
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.
- 3, 4x3, & 8 inch NPS (80, 100x80, & 200mm DN)
- Globe Body Style
- RF | RTJ | BWE Available End Connections
- ASME B16.34 Class 900, 1500 & 2500 Pressure Rating
- ANSI/FCI 70.2 and IEC 60534-4 Class II to V Shutoff
Applications
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.

Actuators
DFC & DFO Linear Spring & Diaphragm Actuators
Model DFC (Fail Closed) and DFO (Fail Open) linear spring and diaphragm actuators are large diaphragm area actuators that allow for low-pressure operation. The spring provides fail safe positioning for a control valve on loss of pneumatic supply pressure. Both DFC and DFO actuators can be used to automate control valves for throttling or on/off control of liquids or gases.
- 3-15 PSIG (0.21-1.03 BARG) or 6-30 PSIG (0.41-2.07 BARG) Input Signal
- 3/8" (9.5mm) | 1/2" (12.7mm) | 3/4" (19.1mm) Valve Stem Compatibility
- 2-1/8" (54mm) | 2-13/16" (71mm) | 3-9/16" (90mm) Yoke Boss Size
- -40°F to 180°F (-40°C to 82°C) Standard Temperature Limitations

390 Series
