🔷 Overview of VINVAL Bellows Seal Globe Valve

The VINVAL bellows seal globe valve is a high-performance industrial valve designed for zero leakage applications.

👉 The key feature of this valve is the metal bellows seal, which replaces traditional packing to completely eliminate stem leakage.

This valve is widely used in:

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

⚙️ Structure of VINVAL Bellows Seal Globe Valve

1. Body

• Material: ASTM A105, F304, F316
• Forged steel construction
• High strength and pressure resistance

2. Bellows Seal

👉 The most critical component

• Made of stainless steel or special alloy
• Prevents leakage at the stem area
• Eliminates traditional packing system

3. Disc

• Controls flow regulation
• Designed for precise throttling

4. Stem

• Connects to handwheel or actuator
• Stable operation under high pressure

5. Bonnet

• Strong structural design
• Ensures overall sealing integrity

🔧 Working principle

The bellows seal globe valve operates as follows:

• The disc moves up and down to regulate flow
• Bellows expand and contract with stem movement
• Prevents any fluid leakage to the outside

👉 Key advantage: zero leakage at the stem sealing area
