Dynamic Stability and Frequency Response
The Fisher control valve boasts excellent dynamic stability and frequency response capabilities. Its shallow membrane cover on the air supply side allows for a smaller chamber volume, resulting in faster response times. With this design, the control valve can respond quickly and effectively under various operating conditions.
Thrust and Service Life
The Fisher control valve can withstand high thrust, and its molded diaphragm can provide thrust corresponding to the size of the diaphragm. Its construction, made of strong, thick-walled cast iron and steel, provides a stable and corrosion-resistant structure that can maintain deformation under overpressure conditions. This results in an extended service life for the control valve.
Suitability for Low Temperature Conditions
The 657 and 667 diaphragm actuators come in various sizes and are available in enhanced product specifications that allow for use in temperatures as low as -50°C. A positioner is recommended to ensure the responsiveness of the actuator at temperatures below -40°C.
Rigid Connection Design
The Fisher control valve features a clamp stem connection design that delivers reliable motion and is easy to install. Without the use of a connecting rod, there is no problem of connection gaps or inaccurate valve positioning.
