Fisher Control Disk Valve Butterfly Valve – Rotary Valves

Fisher Control Disk Valve is a high performance butterfly valve offering excellent throttling performance. The Control Disk valve is able to offer control closer to the target set point in spite of process disturbances allowing the brilliant throttling performance and make this valve preferable to segmented ball valves.

The Control Disk valve body meets PN 10 through PN 40, CL150, and CL300 ratings. Face-to-face dimensions meet EN 558, API 609, and MSS-SP68 standards. Line centering clips provide for versatility to mount and align the same wafer style valve body in different piping configurations (ASME and EN ratings).

The Control Disk rotary valve features an eccentrically-mounted disk with either soft or metal seal, providing capability for enhanced shutoff

Fisher Control Disk Valve Butterfly Valve – Product Features

• Equal 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 variabilit
• Global Standards – valve meets API, ASME, and EN standards, making it suitable for use in all world areas
• PEEK/PTFE bearing as standard – 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 – equal percentage disk reduces operating torque at peak angles of disk opening
• Spline-ended Shaft – splined shaft with clamped lever and single-pivot linkage reduces lost motion between the actuator and the valve shaft
• Improved shaft-disk pinning – spring in the outboard shaft provides support to the drive train and disk, enabling the shaft to be installed in both horizontal and vertical orientations with no detriment to performance or cycle life. This complements the ability to mount the actuator on the left- or right-hand side, enabling access for any installation
• New Spring-Loaded Shaft – the ENVIRO-SEAL packing system can control emissions below the EPA (Environmental Protection Agency) limit of 100 ppm (parts per million)
• Excellent Emissions Capabilities – optional ENVIRO-SEALt packing systems, are designed with very smooth shaft surfaces and live-loading to provide improved sealing, guiding, and loading force transmission. The seal of the ENVIRO-SEAL system can control emissions to below 100 ppm (parts per million)
• Easy Installation – line-centering clips engage the line flange bolts to simplify installation and provide for centering of wafer-style valves in the pipeline. End connections are compatible with EN and ASME standards
