Emerson Process Management's Fisher Control Valves brand has been leading the market for over a century by providing unparalleled solutions for control valves. Their commitment to quality ensures that industries such as oil, gas, chemical, and electric power continue to rely on Fisher control valves for their precise control and performance.
Fisher control valves are used extensively across a range of industrial applications thanks to the brand's reputation for delivering dependable, high-quality solutions. These valves are designed with advanced engineering and crafted with meticulous precision, ensuring they provide excellent performance in even the most demanding conditions.
For industries that require precise control over flow, pressure, and temperature, Fisher control valves are an indispensable tool. With their rigorous testing and proven performance history, these valves have earned their place as one of the few trusted valve solutions in the industry for over 100 years.
The Fisher control valve is known for its exceptional dynamic stability and frequency response. This is attributed to its shallow membrane cover on the air supply side, which results in a smaller chamber volume and reduces response time. As a result, the control valve can respond quickly to a wide range of operating conditions.
Another advantage of the Fisher control valve is its ability to withstand high thrust. Its molded diaphragm is designed to provide thrust that corresponds to the size of the diaphragm. Moreover, its strong and thick-walled cast iron and steel construction ensures stable and corrosion-resistant operation, even under overpressure conditions. This extends the service life of the valve.
The Fisher control valve is also suitable for use in low temperature conditions. Its diaphragm actuators 657 and 667 are available in enhanced product specifications for use at temperatures as low as -50°C. However, it is recommended to use a positioner to ensure the actuator's responsiveness at temperatures below -40°C.
The control valve is designed with a clamp stem connection that delivers motion reliably and is easy to install. The rigid connection design eliminates the need for connecting rods and prevents the problem of connection gaps and inaccurate valve positioning.
