⚙️ Structure of VINVAL Class 800 Ball Valve

The Class 800 ball valve consists of the following main components:

1. Body

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

---

2. Ball

• Precision machined
• Highly polished surface
• Ensures tight sealing when closed

---

3. Seat

• PTFE / RPTFE / metal materials
• Wear and heat resistant

---

4. Stem

• Connects to handle or actuator
• Anti-blowout design

---

5. Packing / Gasket

• Graphite or PTFE
• Prevents external leakage

---

🔧 Working principle

The Class 800 ball valve operates as follows:

• The handle rotates 90°
• The ball rotates with the stem
• When the bore is aligned → full flow
• When perpendicular → flow is blocked

👉 Advantages: fast operation, high sealing performance, low pressure drop.
