Fisher Control valves, which is a brand under Emerson Process Management, has been delivering top-notch control valve solutions for over a century. The brand's reputation for quality control valves has earned it a global reputation among the oil, gas, chemical and electric power industries.
Backed by a century of experience, Fisher Control valves boasts of providing reliable, robust, and durable control valve solutions. The brand's valves come with a range of features and options that make them perfect for numerous industrial applications. With extensive use across industries, Fisher control valves have proven to be a reliable choice for controlling fluid flows accurately.
In the oil and gas industry, Fisher control valves are used to control the flow of oil and gas through pipelines. The valves' robust design makes them ideal for use in harsh environments, ensuring reliable, stable, and accurate control. The brand's chemical control valves are built to handle different types of chemicals, further enhancing their versatility. Additionally, Fisher's electric power control valves can easily handle different operating conditions, including high pressure and high-temperature applications, making them suitable for power generation applications.
Dynamic stability and frequency response are important factors in control valve performance. Fortunately, Fisher control valves excel in both areas. This is due in part to the shallow membrane cover on the air supply side, which reduces response time by minimizing chamber volume. This design allows for quick and accurate response under various operating conditions.
Thrust and service life are additional benefits of using Fisher control valves. These valves are able to withstand high thrust thanks to the molded diaphragm, which provides thrust corresponding to the size of the diaphragm. The strong, thick-walled cast iron and steel construction of the valve also contributes to its stability and corrosion resistance, allowing it to maintain deformation under overpressure conditions and extend its service life.
For low temperature conditions, Fisher control valves are a suitable option. Enhanced product specifications are available for all sizes of diaphragm actuators 657 and 667, enabling use in temperatures as low as -50°C. To ensure responsiveness of the actuator at temperatures below -40°C, a positioner is recommended.
The Fisher control valve's design incorporates a clamp stem connection, which delivers reliable motion and ease of installation. Additionally, the rigid connection design does not use a connecting rod, eliminating the issue of connection gaps and inaccurate valve positioning.
