Cast Iron Valve Body
Cast Iron Valve Body is a core component for industrial valves, designed to deliver reliable fluid control in various pipeline systems. It combines durability, cost-effectiveness, and easy installation, making it a top choice for municipal and industrial applications.
Types of Cast Iron Valve Body
We offer two main variants to meet different working demands: Ductile Iron Valve Body and Gray Iron Valve Body. Ductile Iron Valve Body features high tensile strength and impact resistance, suitable for medium-pressure scenarios.
Gray Iron Valve Body excels in machinability and vibration damping, ideal for low-pressure systems like water supply and HVAC pipelines. Both variants adhere to strict quality standards for stable performance.
Sand Casting for Cast Iron Valve Body
Sand Casting for Cast Iron Valve Body is our primary manufacturing process, ensuring uniform material structure and smooth inner walls. This mature technology minimizes casting defects, guaranteeing consistent wall thickness and structural integrity.
Each casted body undergoes rigorous inspection to eliminate flaws, laying a solid foundation for the valve’s overall performance and service life.
Cast Iron Valve Body Sizes
We provide a complete range of standard sizes: Cast Iron Valve Body DN50, DN80, DN100, DN150, DN200…… These sizes are widely compatible with common industrial valves such as gate valves, globe valves, and check valves.
The standard dimensions ensure easy integration into existing pipeline systems, reducing installation time and costs for our customers.
Quality & Application
Our Cast Iron Valve Body is crafted from high-quality raw materials, with strict quality control throughout the production process. It is widely used in water treatment, municipal pipelines, petrochemicals, and heating systems.
With its excellent performance and competitive price, it has become a reliable choice for global customers seeking cost-effective valve components.
