🔷 Overview of VINVAL Check Valve

The VINVAL check valve is an important industrial valve designed to prevent backflow in piping systems, ensuring safe and stable operation.

👉 It is widely used in high-pressure systems where reliability and tight sealing are critical.

Typical applications include:

• Oil & Gas industry
• Chemical plants
• Steam systems
• Power plants and heavy industries

⚙️ Structure of VINVAL Check Valve

1. Body

• Material: ASTM A105, F304, F316
• Forged steel construction
• Designed for high pressure resistance

2. Disc

• Swing type or lift type
• Opens and closes based on flow direction

3. Spring (optional design)

• Helps close the valve quickly
• Improves backflow prevention efficiency

4. Bonnet

• Bolted or welded type
• Ensures strong sealing performance

🔧 Working principle

The check valve operates as follows:

• When flow moves in the correct direction → valve opens
• When reverse flow occurs → valve automatically closes
• Prevents backflow in the pipeline

👉 This mechanism protects pumps and downstream equipment.
