For more than 100 years, Fisher Control Valves have been the go-to solution for companies in need of high-quality industrial control systems. These valves are designed to meet the needs of a wide range of industrial applications, from the most basic to the most complex.
Whether you work in oil, gas, chemical, or electric power industry, there's a Fisher control valve solution that is tailored to meet your specific needs. From basic to advanced applications, Fisher control valves deliver precise and reliable control of pressure, temperature, and flow parameters, allowing you to optimize your industrial process with confidence.
Fisher control valves are renowned for their state-of-the-art technology, superior quality, and performance. They are continuously tested and improved upon to withstand the toughest operational conditions. With a Fisher control valve, you can rely on its accuracy, durability, and longevity, delivering superior results and keeping your industrial process running smoothly.
The Fisher control valve is known for its excellent dynamic stability and frequency response ability. Its membrane cover on the air supply side is shallow, which reduces response time by creating a smaller chamber volume. With this design, the control valve can quickly respond to various operating conditions.
The Fisher control valve is capable of withstanding high thrust, and its molded diaphragm provides thrust corresponding to the size of the diaphragm. Additionally, its strong construction made of thick-walled cast iron and steel ensures strong stability and corrosion resistance. This design can maintain deformation under overpressure conditions and extend the service life of the valve.
The Fisher control valve's diaphragm actuators 657 and 667 are available in enhanced product specifications for all sizes, which allows them to be used in temperatures as low as -50°C. However, to ensure that the actuator remains responsive at temperatures below -40°C, a positioner is recommended.
The Fisher control valve features a clamp stem connection design that delivers reliable motion and is easy to install. The valve does not use a connecting rod, which helps avoid issues related to connection gaps and inaccurate valve positioning.
