Fisher 657 667 Diaphragm Actuators with DVC2000 DVC6200 Positioner for Oil Gas Chemical Power

Fisher 657 and 667 Diaphragm Actuators, paired with the DVC2000 and DVC6200 digital valve controllers, deliver reliable, high-performance pneumatic control for linear valves in oil and gas, chemical, power, and industrial process applications. Designed for precision throttling and on/off service, these actuators combine robust construction with smart positioner technology to optimize process control, reduce maintenance, and improve operational safety.

• The integral mounting pad eliminates the traditional mounting bracket and reduces the number of parts required to mount.
• Incorporates an integral air passage that eliminates the need for external tubing and fittings when paired with a Fisher FIELDVUE instrument.
• Both 657 and 667 actuators are compatible with instruments that utilize traditional bracket-based mounting kits.
• Spring rates, travel stops, and manual operators are available for nearly any control valve application.
• Molded diaphragm in a deep casing minimizes area change throughout the travel.
• Shallow pressure-side casing reduces volume to minimize response time.
• Rugged thick-walled cast iron and steel construction ensures long service life and corrosion protection.
• Smart DVC2000/DVC6200 positioners enable digital communication, diagnostics, and loop tuning.
• SIL-capable design supports safety instrumented system requirements.
• Quick and easy installation with multiple mounting options for diverse valve configurations.
