Fisher® Control Valves - Most Reliable in the Process Control Industry
Control Valves are valves used in pipelines to control operating conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to a process signal.

Sliding Stem Valves
Globe, angle, and 3-way valves offer a broad range--from DN15 to 600 (NPS 1/2 to 24) low-flow valves to DN 500 (NPS 20) and larger for demanding high-pressure steam and hydrocarbon service.

Rotary Valves
When capacity and performance are the requirements rotary valves are the answer. Popular rotary products include butterfly, eccentric plug, full bore pipeline, high performance butterfly and segmented ball.
 

Sanitary Valves
Sanitary valves are designed to meet the stringent demands of today's state-of-the-art Life Science facilities.

 

Fisher® Digital Valve Controllers
Digital valve controllers use microprocessors and have become the dominant replacement technology for conventional and electro-pneumatic positioners since the mid 1990s. Fisher® FIELDVUE™ digital valve controllers integrate functionality far beyond the traditional analog or pneumatic positioner. The benefits of using a FIELDVUE digital valve controller include: Availability of equipment alerts to notify the user of pending issues, automated configuration, calibration and tuning , and access to advanced levels of valve assembly diagnostics. This provides consistent and predictable knowledge of valve assembly performance and condition regardless who performs the task.


Fisher® FIELDVUE Software
ValveLink Software allows you to streamline maintenance activities and optimize process control operations.



FOUNDATION™ Fieldbus Communication
FIELDVUE DVC6200f fieldbus digital valve controllers are approved for non-incendive, intrinsic safety, flameproof and explosion proof applications.


HART® Communication Protocol
FIELDVUE DVC6200 and DVC2000 digital valve controllers are HART communication instruments approved for non-incendive, intrinsic safety, flameproof and explosion proof applications.

 

Fisher® Positioners
Positioners are most commonly used to move a control valve to a specified position so that a process meets specific parameters (flow, pressure, temperature). Fisher® positioners have the reputation of providing the most accurate, robust, and reliable performance in the industry.


Electro-Pneumatic Positioners
Electromechanical positioners are conventional pneumatic positioners that have an additional integrated electro-pneumatic transducer.



Pneumatic Positioners
Conventional pneumatic positioners receive a pneumatic control signal and translate that into the appropriate pneumatic output signal to the control valve actuator.




Fisher® Field Instrumentation

Fisher® field mounted instruments provide monitoring and control to final control devices. Transducers, controllers, volume boosters, solenoids and switches are used to monitor and control flow, temperature, pressure and level variables in the process industry.

Level Sensors
Fisher Level Sensors, in conjunction with either FIELDVUE DLC3000 Series digital level controllers or 2500 Series controllers and transmitters, are designed to measure changes.



Level Switches
On-off switch that senses high or low liquid levels. A displacer is used as the sensor and is located in an external cage that mounts to the outside of a vessel.



Level Transmitters
Both digital electronic and pneumatic displacement level controllers are used for accurate level measurement or precision level loop control.




Liquid Level Controller - Electric
The electric on-off level controller is used to sense liquid level and when used in conjuction with the Fisher® easy-Drive™ electric actuator form a fully electric level control loop which eliminates pneumatic controller and dump valve venting.


Liquid Level Controllers - Pneumatic
The pneumatic level controllers sense the level of a liquid or a liquid-to-liquid interface, compare the level with a desired value (set point) and produce a pneumatic signal that can operate an actuator control valve.



Pneumatic Pressure Controllers
Once again Emerson Process Management reinforces its long-standing commitment to technological excellence with a complete line of pressure controllers.


Pneumatic Temperature Controllers
Pneumatic temperature controllers compare process temperature with an operator- adjusted set point. The controller delivers a pneumatic signal to a control element.



Valve Accessories
Emerson Process Management manufactures a broad range of accessories for use with control valves.





Actuators
An actuator is a mechanical device used to control a valve, damper, etc.


Pneumatic Actuators
A pneumatic actuator provides high stem force output for demanding service conditions. These actuators are usually air operated but some can be self operated by the process fluid.


Electric Actuators
An electric actuator provides a stem force output for a variety of process applications by using electricity as the power source.




Manual Actuators
Fisher manual actuators are used in applications that require manual positioning of valves.







Fisher® Severe Service
For decades Emerson’s severe service team has been providing global customers with Fisher® severe service control valve solutions. Whether it is severe service applications for the power, hydrocarbon, chemical or pulp and paper industry, Emerson’s technical experts have provided sound solutions to address critical applications for aerodynamic noise, cavitation and out-gassing issues, as well as particulate erosion areas.

Aerodynamic Noise Control
Control valve technologies used to reduce the noise of compressible flows via several techniques of frequency shifting, discreet pressure staging, trim passage shape and/or adequate expansion areas.



Cavitation Control
Cavitation control trim constructions are designed to eliminate, or minimize the damaging effects of cavitating applications.




Engineered Solutions
Complete valve solutions, custom engineered for the customer's specific application.



Steam Conditioning
Steam Conditioning is the combination of pressure reduction and temperature reduction of superheated steam to fit process needs and protect downstream equipment
