Proper control valve selection is critical for your process loop. Performance and safety are two of the key concerns in plants today. Since control valves are the only devices in the control loop that actually move to adjust the process, their performance is fundamental. If they don’t perform properly, you can’t meet production schedules and maintain product quality. Then there’s safety. When there’s a lack of knowledge of control valve position or operation, you could threaten worker safety, cause environmental concerns, and potentially damage operating equipment. That’s a lot of pressure...

Your control valves are critical to the performance and safety of your process, but when there are so many to choose from, you may feel uncertain about which ones offer the most value.

Emerson’s Fisher control valves and instruments put you on the path to better performance and safety. We realize there’s a good chance that your control valves and instruments will need to last you decades—even in harsh environments. By selecting Fisher brand control valves (globe, rotary, severe service), controllers, and instruments you can more easily meet your performance and safety requirements. This is possible because their as-designed performance integrity has been tested to ensure the highest degree of lasting reliability is achieved. Fisher valves and instruments can help you...

Since 1880, Fisher valves and instruments have been trusted by the process control industry. Today, the easily recognizable all-green paint identifies valves carrying the Fisher brand. Meet changing process demands with valve trim variations. Fisher globe control valves have a selection of cages or plugs that can be interchanged to modify the inherent flow characteristic to meet changing flow demands. Globe Control Valves u p5 Get high capacity, precise flow control for a lower total cost of ownership. Fisher rotary control valves provide high capacity control across a broad range of...

Globe Control Valves Meet changing process demands with control valve trim variations. Fisher globe control valves are available in a variety of sizes (NPS ½ thru 36) and provide users with performance and flexibility. They can help solve an array of application needs from big to small, hot to cold, general to severe. Fisher globe control valves have a selection of valve cages or plugs that can be interchanged to modify the inherent flow characteristic to linear, equal percentage, or quick opening to meet capacity demands from 0.0001 Cv up to 12,000 Cv. Fisher easy-e™ control valves...

Globe Valves Globe Valves use a linear motion to move a closure member into and out of a seating surface. They have a body distinguished by a globular-shaped cavity around the port region. Many single-seated valve bodies use cage or retainer-style constructions to retain the seat ring, provide valve plug guiding, and provide a means for establishing particular valve flow characteristics. Cage or retainer-style single-seated valve bodies can also be easily modified by the change of trim parts to provide reduced capacity flow, noise attenuation, or reduction or elimination of cavitation. u...

Rotary Control Valves Get high capacity, precise flow control for a lower total cost of ownership. Rotary control valves generally have much higher maximum capacity than globe valves for a given body size. This fact makes rotary control valves attractive in applications where the pressure drop is rather small. Rotary control valves include ball, segmented ball, high-performance butterfly, and eccentric plug styles with such familiar names as Fisher Vee-Ball™ and Fisher Control-Disk™ valves. What’s your challenge? The criterion of capacity or size can be an overriding constraint on control...

Ball Valves Ball Valves with trunnions help maintain consistent flow rates for high capacity, heavy-duty applications. They have a rotatable ball with a cylindrical flow passage through the center to the control flow. When the ball is turned one-quarter of the way, the flow stops. The port of a full-port or full-bore ball valve equals the pipeline diameter and presents little or no restriction to flow to allow for pigging when not attenuated. The port of a reduced-port or reduced-bore ball valve is smaller than the pipe to absorb a small amount of pressure drop. u V250 | V260 | V270 | V280...

Critical and Severe Service Control Valves Extend valve operating life in the most difficult installations. Fisher severe service control valves are used in the most difficult installations within your process plant. These installations commonly including cavitating, erosive, corrosive, flashing, outgassing, noisy, high pressure, high temperature, high pressure drop, or high velocity media that can cause premature failure. A severe service control valve may or may not be a critical service valve—one that’s essential to the operation of the plant. To maximize longevity in harsh conditions,...

Noise Control Trims Aerodynamic and Hydrodynamic Noise Control Trims are trusted and tested to protect your personnel and the surrounding environment from excessive noise risks. High pressure drops and high mass flows involving liquids, gases, vapors, or steam can lead to unwanted and dangerous noise levels. Allowing this noise to continue puts you at risk of fenceline noise regulation fines or potential employee hearing loss. High noise levels can also lead to equipment damage through vibration and process control issues. Mitigate your risk by choosing Fisher products. u Whisper Trim I |...

Controllers and Instruments Modulate control valves and monitor process variables. A wide selection of Fisher digital, pneumatic, and electronic instruments control valve position and variables such as level, pressure, or temperature. They are added to control valves for five basic reasons: to improve process control; improve safety; monitor the valve responsiveness; diagnose issues; and improve valve performance or speed of response. We were the first to develop digital valve controllers—Fisher FIELDVUE™ instruments—and performance diagnostics for improved control and predictive...
