Over the years, Fisher Control valves has gained recognition as a leading supplier of control valves in various industrial fields such as oil, gas, chemical, and electric power.
The company has established a reputation for delivering reliable and efficient control valve solutions that meet the needs of their clients. They offer a range of control valve products such as butterfly valves, globe valves, and ball valves, all designed to address individual application requirements. Clients can choose from standard control valves, optimized for general-purpose applications, or premium control valves that are tailored to specific process demands.
With a mission to provide the best control valve solutions that match individual demands, Fisher Control Valves has put in place an extensive distribution network to serve its global clients. Fisher Control valves' commitment to quality and innovation has made them a preferred choice for many industrial organizations across the globe.
The Fisher control valve exhibits exceptional dynamic stability and frequency response capabilities. This is due to the shallow membrane cover on the air supply side, which reduces the chamber volume and guarantees a faster response time. Consequently, the control valve can respond quickly to different operating conditions.
The Fisher control valve is known for its ability to withstand high thrust, thanks to the molded diaphragm that provides thrust proportional to the diaphragm size. Furthermore, its robust, thick-walled cast iron and steel construction ensures strong stability and corrosion resistance, enabling the valve to maintain deformation under overpressure conditions. This results in extended service life.
The diaphragm actuators 657 and 667 are available in enhanced specifications for all sizes, allowing their use at temperatures as low as -50°C. However, a positioner is recommended to ensure the responsiveness of the actuator when temperatures drop below -40°C.
The Fisher control valve is designed with a clamp stem connection that delivers motion reliably and is easy to install. The absence of a connecting rod eliminates the issue of connection gaps and inaccurate valve positioning, making it a durable and reliable choice.
