DK56-FB Electric Cast Steel Flanged Butterfly Valve for Plant Utility Systems
The DELCO VALVE DK56-FB Electric Cast Steel Flanged Butterfly Valve offers motorized shutoff for compatible industrial utility and liquid-service pipelines. Its cast steel body provides an alternative where stainless steel construction is not required by the service specification. Electric actuation supports centralized operation, while flanged ends suit permanent plant piping and scheduled valve replacement.
Size Range: DN40-DN1200
Material:Cast Iron, WCB, SS304/316 etc.
Connection Standard:GB / ANSl /JIS /DIN
Equip plant utility pipelines with electric shutoff and a cast steel body selected for the service. The DK56-FB balances material requirements, automation needs, and practical maintenance access.
✅Cast Steel Body for Industrial Piping Specifications
Addresses projects specifying a cast steel pressure boundary, with service suitability determined by the valve’s pressure-temperature rating and internal materials.
✅Material Choice Aligned with Project Budget
Offers an alternative to a stainless steel body where fluid chemistry and environmental conditions permit, helping avoid unnecessary material expenditure.
✅Centralized Shutoff for Distributed Utilities
Motorized opening and closing allows operators to manage isolation points across plant utility networks without operating each valve by hand.
✅Flanged Ends for Defined Connection Requirements
Supports bolted installation into project pipework, with flange dimensions and pressure class matched to the piping specification.
✅Serviceable Installation for Shutdown Planning
The valve can be unbolted and removed during an isolated, depressurized shutdown, simplifying replacement without cutting adjacent pipework.

Industry Applications
-
Oil & Gas
For compatible utility-water and auxiliary cooling lines where project specifications call for cast steel valves. Motorized shutoff supports isolation of equipment services during maintenance and operational changeovers. -
Chemical & Petrochemical
For non-aggressive utility fluids and compatible liquid services where a stainless steel body is unnecessary. Corrosive process duties require separate assessment of the body, trim, and sealing materials. -
Power Generation
For service-water distribution and auxiliary cooling systems supplying plant equipment. Electric operation helps coordinate isolation of utility branches during planned equipment outages. -
Food & Pharmaceutical
For non-product-contact utility circuits serving production areas, subject to fluid and environmental compatibility. The cast steel industrial body is intended for utility selection rather than an assumed hygienic process application. -
Water & Wastewater
For compatible plant-water and pumping-system isolation duties where cast steel construction is specified. Water chemistry, internal protection, and seat selection determine suitability for the particular treatment stage. -
HVAC & District Heating
For closed-loop cooling and heating-water isolation within the selected valve’s operating limits. Cast steel construction offers a material option where system water treatment and corrosion management support its use.
