Fisher Control valve
Control-Disk Valve Features Equal percentage flow characteristic Anequal percentage flow characteristic provides an improved throttling range comparable to that of a segmented ball valve. This improved capability allows you to control closer to the target set point, regardless of process disturbances, which results in a reduction in process variability. Global Standards— The valve meets API, ASME, and EN standards, making it suitable for use in all world areas. PEEK/PTFE bearing as standard The PTFE-lined PEEK bearing is a low friction, low wear bearing. It allows the valve to operate under high pressure drops for a high cycle life while maintaining low torque. The “drop-in” bearing design enables fast, easy maintenance. Lower Operating Torques— The equal percentage disk reduces operating torque at peak
angles of disk opening.
