Dynamic stability and frequency response
The Fisher control valve has outstanding dynamic stability and frequency response capabilities. This is because the membrane cover on the air supply side is shallow, resulting in a smaller chamber volume, which in turn reduces the response time of the valve. As a result, this design allows the control valve to respond quickly under different operational conditions.
Thrust and service life
The Fisher control valve is capable of withstanding high thrust, with its molded diaphragm delivering thrust corresponding to the size of the diaphragm. The control valve's sturdy, thick-walled cast iron and steel construction provides excellent stability and corrosion resistance, which enables it to maintain deformation under overpressure conditions and extend its service life.
Suitability for low temperature conditions
The diaphragm actuators 657 and 667 are available in enhanced product specifications for all sizes, making them suitable for use in temperatures as low as -50°C. To ensure actuator responsiveness at temperatures below -40°C, it is recommended to use a positioner.
Rigid connection design
The Fisher control valve is designed with a clamp stem connection, which delivers motion reliably and is easy to install. This design avoids the use of a connecting rod, eliminating the problem of connection gaps and inaccurate valve positioning.
