For over a century, Fisher Control Valves have been renowned for providing superior quality control valve solutions that exceed customer expectations. A brand of Emerson Process Management, Fisher Control Valves have acquired a reputation for reliability and innovation in the industry.
These valves are widely used in a variety of industrial fields including, but not limited to, oil, gas, chemical and electric power. Their reliable and consistent performance make them an ideal choice for critical applications.
When it comes to dynamic stability and frequency response, the Fisher control valve really shines. This valve features a membrane cover on the air supply side that is intentionally shallow, creating a smaller chamber volume that can reduce response time. These design elements enable the Fisher control valve to respond quickly under a range of operating conditions.
Another key feature of the Fisher control valve is its ability to withstand high thrust. The molded diaphragm of this valve provides thrust corresponding to the size of the diaphragm. The valve also features strong, thick-walled cast iron and steel construction that offers excellent stability and corrosion resistance. This design helps the valve to maintain deformation even under overpressure conditions, extending its service life.
One area where the Fisher control valve really stands out is its suitability for low temperature conditions. In fact, all sizes of diaphragm actuators 657 and 667 are available in enhanced product specifications designed for use at temperatures as low as -50°C. However, it's important to note that a positioner is recommended to ensure the responsiveness of the actuator at temperatures below -40°C.
Finally, the Fisher control valve is designed with a clamp stem connection. This design element allows for reliable motion delivery and easy installation. Unlike valves that use connecting rods, this design avoids the problematic connection gaps and inaccurate valve positioning that can cause issues with other products.
