Investment Cast Check Valves

Fly Investment Casting Factory supplies various check valves made by investment casting processs in China. 

1. Materials

Check valves are typically constructed from durable materials to withstand diverse operating conditions. Common materials include:

Metals: Stainless steel, brass, and cast iron for high-pressure or corrosive environments.

Plastics: PVC and polypropylene for lightweight, chemical-resistant applications.

Composites: Rubber-coated discs or seals to enhance durability and prevent leakage.

2. Manufacturing Process

Check valves, especially the check valve main body, check valve discs and check valve housings are mainly made in investment casting process. 

Surfaces are refined To ensure smooth operation and tight sealing, machining process is required. After casting and machining, the check valve main body will be assembled with other check valve components such as Flaps, discs, or poppets are integrated with springs or hinges to enable one-way flow.

Testing is also a very important process to control quality of investment casting check valves. Valves undergo pressure and leak testing to verify functionality.

3. Core Applications

Investment cast check valves are vital across industries such as, 

plumbing: Prevent backflow in water supply systems, protecting against contamination.

Industrial Machinery: Used in hydraulic and pneumatic systems to maintain unidirectional fluid flow.

Medical Devices: Ensure safe one-way passage in infusion pumps and dialysis equipment.

Automotive: Manage fuel flow in engines and exhaust systems.

By automatically allowing forward flow and blocking reverse flow, check valves enhance safety and efficiency in countless applications.
