DK56-FB Electric Cast Iron Flanged Butterfly Valve for Water & HVAC Systems
The DELCO VALVE DK56-FB Electric Cast Iron Flanged Butterfly Valve provides motorized isolation for water distribution, cooling circuits, and HVAC pipework. It suits general water-service projects where cast iron meets the piping specification and procurement cost matters. Electric operation brings branch and equipment isolation into centralized control, while bolted flange connections accommodate planned replacement.
Size Range: DN40-DN1200
Material:Cast Iron, WCB, SS304/316 etc.
Connection Standard:GB / ANSl /JIS /DIN
The Electric Cast Iron Flanged Butterfly Valve offers economical motorized isolation for water distribution, cooling circuits, and HVAC systems. Electric actuation enables centralized operation, while flanged connections simplify removal for maintenance.
✅Cost-Conscious Selection for General Water Service
Cast iron offers an economical body-material option for compatible water duties that do not require stainless steel or cast steel construction.
✅Equipment Isolation from a Central Control Point
Electric actuation allows operators to isolate individual equipment branches without walking between valves throughout the facility.
✅Practical for Pump and Heat-Exchanger Connections
The butterfly valve layout accommodates shutoff duties around water-handling equipment, where installation space and service access influence selection.
✅Bolted Installation for Replacement Work
Flanged ends allow removal of the valve during maintenance without cutting the pipe, provided replacement dimensions match the existing installation.
✅Straightforward On/Off Automation
Motorized quarter-turn operation supports routine opening and closing of water lines without a dedicated compressed-air supply.

Industry Applications
-
Oil & Gas
For compatible non-hydrocarbon utility-water systems around support facilities and equipment cooling installations. Cast iron suitability depends on the project piping specification and operating conditions. -
Chemical & Petrochemical
For non-corrosive cooling and auxiliary-water circuits serving process equipment. This configuration addresses utility isolation rather than assuming compatibility with aggressive chemicals. -
Power Generation
For plant service-water branches and compatible cooling-water connections. Motorized isolation helps take individual equipment circuits out of service during scheduled maintenance. -
Food & Pharmaceutical
For non-product-contact cooling and building utility lines supporting production operations. Cast iron construction is suited to compatible utility duties rather than hygienic product-transfer applications. -
Water & Wastewater
For distribution mains, treatment-plant water lines, and pumping-station isolation. Seat materials, corrosion protection, and fluid characteristics determine suitability for each water or wastewater duty. -
HVAC & District Heating
For isolating chiller connections, heat-exchanger branches, and circulating-water circuits. Electric operation supports equipment changeover and maintenance isolation within the valve’s rated temperature and pressure limits.
