Valve Bodies We Cast
As a premier valve casting supplier, we utilize advanced soluble wax techniques to achieve the complex internal flow paths required for modern industrial valves.

The Importance of the Valve Body
The valve body is the primary pressure boundary of a valve assembly. Any internal porosity or micro-cracking in the casting can lead to catastrophic failure, severe environmental damage, and costly downtime. This is why valve body investment casting requires exceptional metallurgical control.
At Neocast Alloys, an ISO and PED certified investment casting company, we guarantee the structural integrity of every valve body we produce. Our in-house NDT lab performs rigorous radiography and dye penetrant testing to ensure zero-defect delivery.
By utilizing the investment casting process, we deliver near-net-shape valve casting parts with excellent internal cavity finishes, reducing fluid turbulence and significantly lowering the machining costs associated with traditional sand castings.
Frequently Asked Questions
Q.What is valve body investment casting?
Valve body investment casting is a specialized manufacturing process using a wax pattern and ceramic shell to create the outer pressure-retaining casing (the 'body') of an industrial valve. It yields a much smoother and more accurate casting than traditional sand casting.
Q.Why is investment casting better for valve bodies?
It provides superior internal surface finishes that reduce fluid friction, minimizes the risk of internal porosity (crucial for high-pressure applications), and significantly reduces the amount of expensive CNC machining required to finish the flanges and internal seating.
Q.What materials do you cast valve bodies in?
We cast valve bodies in standard Carbon Steel (WCB/WCC), Stainless Steel (CF8M/CF3M), and advanced alloys like Duplex (CD4MCU), Super Duplex, and Nickel Alloys for highly corrosive petrochemical and marine environments.
Q.Are your valve body castings tested for leaks?
Yes, absolute pressure integrity is our standard. Every valve body undergoes comprehensive NDT, including 100% Radiographic Testing (X-ray) and Dye Penetrant Testing to guarantee zero porosity and no leakage.
