- Gate, Globe & Check Valve Castings
Investment Castings for Industrial Flow-Control Components
What Are Gate, Globe & Check Valve Castings?
Gate, globe, and check valves perform distinct flow-control functions, yet all require robust pressure-retaining components with reliable geometry. Gate valves isolate flow, globe valves regulate it, and check valves prevent reverse flow. Each function demands unique internal architecture, such as specific gate channels, directional flow paths, or internal closure cavities.
Investment casting creates these internal forms near net shape, making it ideal for small to medium-sized precision components with intricate passages. Rainbow Technocast develops castings from customer drawings to optimize material usage and ensure seamless downstream machining across carbon, stainless, duplex, and nickel alloys.

Why Investment Casting for Gate, Globe & Check Valve Components?
The intricate internal passages of flow-control valves are difficult to produce efficiently through machining alone. Investment casting solves this by reproducing complex features, ribs, bosses, and transitions directly within ceramic shell molds, delivering near-net-shape parts before final surface machining begins.
This near-net-shape approach provides design flexibility and minimizes excess material, which is especially beneficial when casting high-value stainless, duplex, or nickel alloys. Controlled process parameters ensure reliable repeatability across ongoing batch production.

Frequently Asked Questions
Do you manufacture complete valves?
Rainbow Technocast’s core offering is investment casting and machining of engineered components. The manufacturing scope for a particular project is established from the customer’s component drawing and purchase specification.
Can gate, globe and check valve components be manufactured in stainless steel?
Yes. The company’s published material range includes multiple austenitic stainless, martensitic, duplex and super-duplex grades as well as carbon and low-alloy steels.
Can NDT be carried out on valve castings?
Yes. Available facilities include liquid penetrant testing, magnetic particle inspection and radiographic testing. The required NDT method and acceptance standard should be specified for the project.
Can pressure-containing components be tested for leakage?
Rainbow Technocast lists hydro-pressure testing equipment for pressurised components. Testing requirements should be defined in the customer’s technical specification.
Can you manufacture from a customer's existing tooling?
Existing tooling would first need to be evaluated for compatibility with the foundry’s pattern-making and process requirements. Where necessary, new tooling can be developed from the supplied component drawings or models.
