When it comes to dynamic stability and frequency response, the Fisher control valve is an excellent choice. Thanks to its innovative design, the valve boasts impressive stability and is able to respond quickly under a variety of operating conditions. The shallow membrane cover on the air supply side helps to reduce response time, while the smaller chamber volume boosts response speed even further.
Apart from its dynamic stability, the Fisher control valve is also known for its high thrust and impressive service life. The molded diaphragm delivers thrust based on the size of the diaphragm, and the valve's cast iron and steel construction ensures excellent stability and corrosion resistance. As a result, the valve remains stable even under overpressure conditions and can last for an extended period of time.
If you need a valve that can handle low temperature conditions, the Fisher control valve is an excellent choice. The diaphragm actuators 657 and 667 come in enhanced product specifications that allow them to be used in temperatures as low as -50°C. However, a positioner is recommended for temperatures below -40°C to ensure that the actuator remains responsive.
Finally, the Fisher control valve features a rigid connection design that makes installation easy and ensures reliable motion transfer. The clamp stem connection eliminates the need for a connecting rod, which can lead to connection gaps and inaccurate valve positioning.
