DFRP Rotary Pneumatic Piston Actuator
-
Used in many types of demanding applications involving splined shaft rotary control valves -
Can be positioned for either push-down-to-open or push-down-to-close action
DFLP Linear Pneumatic Piston Actuator
-
DFLP linear double-acting pneumatic piston actuators are designed for high force applications. When combined with a positioner or a two-position control signal, DFLP actuators can be used for throttling or on/off control. DFLP actuators will always require a volume tank in order to hold a fail position.
DFR Rotary Spring & Diaphragm Pneumatic Actuator
-
Model DFR rotary 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. DFR actuators can be used to automate control valves for throttling or on/off control of liquids or gases.
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.
DFN Yokeless Spring & Diaphram Actuator
-
The DFN is a bracket-mounted, direct acting, spring and diaphragm actuator. DFN actuators are typically used to operate butterfly valves, chokes and louvers for throttling or on/off control.
590 Flangeless Full Ball Control Valve
-
Flangeless full ball control valves suited for high flow, low pressure drop services.
-
Model 590 full ball style control valves are used in all kinds of demanding applications, oil and gas production and chemical process industries. It is also suited to high flow, low pressure drop service. The 590 series is used in both throttling and on/off control of liquids or gases. The straight through unrestricted flow path provides higher capacity than globe style valves. A splined shaft provides accurate control in throttling operations and flexibility in actuation options.
570 Flangeless Segmented Ball Valve
-
Flangeless segmented ball control valves suited for high flow, low pressure drop services.
-
Model 570 segmented ball style control valves are used in all kinds of demanding applications, oil and gas production and chemical process industries. It is also well suited for high flow, low pressure drop service. The 570 is used in both throttling and on/off control of liquids or gases. The straight through unrestricted flow path provides higher capacity than globe style valves. A splined shaft provides accurate control in throttling operations and flexibility in actuation options.
DF270 Integral Valve & Actuator
-
Heavy duty, compact control valve.
-
DF270 integral control valves are rugged and designed for demanding tight-space applications. The compact design makes installation and maintenance more convenient than traditional valve and actuator assemblies while offering the same functionality.
DF234 Integral Valve & Actuator
-
Compact dump valve for tough fluid applications that require easy serviceability.
-
DF234 integral control valves are primarily designed for on/off control of fluids or gasses and may also be adapted for throttle control. These tough, compact valves feature a low-profile, lightweight design that fits into tight locations and makes for easy handling. The DF234 is well suited for high pressure fluid or gas applications up to 2,250 PSIG (155 Bar).
DF100 Integral Valve & Actuator
-
Compact dump valve for tough fluid applications.
-
DF100 integral control valves are primarily designed for on/off fluid control and may also be adapted for throttle control. These tough, compact valves are ideal for use in oil and gas separators, treater, scrubbers or as dump valves. The DF100 is well suited for high pressure fluid applications up to 2,250 PSIG (155 Bar).
320 Series
-
320 AxFlo Trim is a high resistance, multi-stage, axial flow path trim to combat erosive service.
-
320 AxFlo Anti-Cavitation trim is a heavy duty dirty service trim option designed for entrained particulate and high pressure drop applications. AxFlo trim offers multi-stage protection against cavitation and erosion. You can expect enhanced trim life when using AxFlo trim because pressure gets distributed over the length of the valve plug across multiple STAGES. Each STAGE is not exposed to the full pressure differential, and on properly sized 320 valves, the amount of pressure drop per STAGE is controlled to prevent cavitation.
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. 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.
