The Fisher™ Control-Disk™ Rotary Valve is engineered for exceptional control performance in demanding industrial applications. Its advanced design offers a modified equal percentage flow characteristic, providing a wider throttling range compared to segmented ball valves . This enhanced capability allows the valve to maintain control over the target setpoint despite process disturbances, minimizing variability and ensuring stable operation .
The Fisher™ Control-Disk™ Rotary Valve is engineered for exceptional control performance in demanding industrial applications. Its advanced design offers a modified equal percentage flow characteristic, providing a wider throttling range compared to segmented ball valves . This enhanced capability allows the valve to maintain control over the target setpoint despite process disturbances, minimizing variability and ensuring stable operation .
Constructed for durability and reliability, the valve features a pressure-assisted seal for tight shut-off and a reinforced expansion pin system that reduces hysteresis and wear in the drive system . Its robust design is tested to withstand extreme conditions, ensuring long-term performance in general service, as well as acidic fluid and gas applications . With external spring configuration allowing for flexible horizontal or vertical mounting, the Control-Disk™ valve combines superior performance with installation versatility .
Key Features:
Superior Control Performance: Delivers a wider throttling range and better control stability than segmented ball valves, reducing process variability .
Robust & Durable Design: Key components are designed and tested for long service life. The valve features a corrosion-resistant powder coat on all steel parts and is constructed with materials suitable for acidic services .
Reduced Maintenance: The improved expansion pin system ensures an effective, long-lasting disc-to-shaft connection and allows for easy disassembly for maintenance .
Tight Shut-Off: Both metal and soft seals are pressure-assisted, ensuring tight shut-off (up to Class VI per FCI 70-2) even under declining pressure conditions .
Global Compliance: Meets major international standards including SIL, PED, NACE, ATEX, and fugitive emissions requirements, ensuring global applicability and safety .
