Fisher Control valves, a brand owned by Emerson Process Management, has been offering top-quality control valve solutions for over a century. These valves have found widespread application in diverse industrial sectors, including the oil, gas, chemical, and electric power industries.
Emerson Process Management, a business division of Emerson Electric Co., is a global leader in manufacturing automation and control systems across several industry verticals. Fisher valves operate based on the knowledge and experience of their predecessors, who developed the "Fisher governor," a revolutionary device for the regulatory control of fuel to steam engines. Subsequent innovations led to the creation of Fisher control valves, achieving unprecedented levels of control and precision when automating industrial processes.
As a testament to their efficiency and reliability, Fisher control valves have been awarded several excellence awards, including the CEATEC Award. The company has made significant investment into technology and research, consistently providing innovative control solutions for industrial applications.
Dynamic stability and frequency response
The Fisher control valve is engineered with exceptional dynamic stability and frequency response capabilities. Its air supply side features a shallow membrane cover, which reduces chamber volume and enables faster response time. This design allows the control valve to respond quickly to a variety of operating conditions.
Thrust and service life
The Fisher control valve is built to withstand high thrust, and its molded diaphragm can provide the necessary thrust based on the size of the diaphragm. Furthermore, its robust, thick-walled cast iron and steel construction ensures strong stability and corrosion resistance, maintaining deformation under overpressure conditions and extending service life.
Suitability for low temperature conditions
For use in low temperature conditions as low as -50°C, the Fisher control valve offers enhanced product specifications for all sizes of diaphragm actuators, while a positioner is recommended to ensure actuator responsiveness at temperatures below -40°C.
Rigid connection design
The Fisher control valve is designed with a clamp stem connection to deliver reliable motion and easy installation. With no connecting rod, there's no issue of connection gaps or inaccurate valve positioning.
