Water and wastewater systems depend on reliable valves to control, regulate and isolate the flow of water. The valve body is one of the most important components because it contains the flow passage and provides the structure for other valve components.
For this reason, industrial valve casting plays an important role in producing strong, dimensionally accurate valve bodies for water treatment plants, pumping stations, pipelines and other water infrastructure.
What Is Industrial Valve Casting?
Industrial valve casting is the process of producing valve bodies and related components by pouring molten metal into a suitable mold.
Casting allows manufacturers to produce complex valve body shapes with features such as:
- Internal flow passages
- Flanged connections
- Mounting points
- Bonnet connections
- Machining allowances
The casting process selected depends on the valve design, material, component size, production volume and required quality.
Why Are Cast Valves Used in Water Applications?
Water systems can require valves in a wide range of sizes and configurations. Cast valve bodies can provide an efficient way to produce these components with the required structural geometry.
Common applications include:
- Water treatment plants
- Water distribution systems
- Pumping stations
- Sewage treatment plants
- Wastewater pipelines
- Industrial water systems
- Irrigation systems
Common Valve Types
Different valve designs are used depending on the flow-control requirement.
Gate Valves
Gate valves are commonly used for on/off flow isolation in pipelines and water systems.
Butterfly Valves
Butterfly valves use a rotating disc to control or isolate flow and are often considered where compact valve designs are beneficial.
Check Valves
Check valves help prevent reverse flow in pipelines and pumping systems.
Globe Valves
Globe valves can be used where flow regulation is required.
The appropriate valve depends on the system’s pressure, flow, media and operating requirements.
Materials Used for Valve Castings
Material selection depends on the operating environment and valve specification.
Common materials include:
Cast Iron
Cast iron can provide good castability, machinability and cost efficiency for suitable water-service applications.
Ductile Iron
Ductile iron provides higher strength and greater ductility than conventional grey cast iron, making it suitable for many demanding valve-body applications.
Cast Steel
Cast steel may be selected for applications requiring specific mechanical properties and operating capabilities.
The final material should always be selected according to the valve design, pressure-temperature requirements, water chemistry, applicable standards and OEM specifications.
Lost Foam Casting for Valve Bodies
For suitable valve body designs, Lost Foam Casting can provide advantages when complex geometries are required.
Potential benefits include:
- Complex component shapes
- Reduced parting lines
- Reduced core requirements for suitable designs
- Near-net-shape production
- Potentially reduced machining
Process suitability depends on the specific valve design, material, size, tolerances and production requirements.
