🔷 What is a VINVAL 3PC Welded Ball Valve Class 800?

The VINVAL Butt Weld 3PC Forged Steel Ball Valve (Class 800) is a high-performance industrial valve manufactured from forged steel with a three-piece (3PC) body design and butt weld (BW) connection, ensuring excellent sealing performance and high operational safety in high-pressure systems.

It is widely used in industries requiring durability, pressure resistance, and stable long-term operation.

⚙️ Technical Specifications

• Size Range: 1/2” – 2”
• Pressure Rating: Class 150 – Class 2500 (Class 800 commonly used)
• Body Materials: ASTM A105N, A350 LF2
• Connection Type: Butt Weld (BW)
• Temperature Range: -29°C to 425°C

📐 Design Features & Performance Advantages

✔️ 1. High strength and pressure resistance

The valve operates reliably under pressures from Class 150 to Class 2500, making it suitable for oil & gas, chemical, and high-pressure hydraulic systems.

✔️ 2. Excellent sealing performance

Precision machining of the ball and seat ensures extremely low leakage and high operational safety even in demanding environments.

✔️ 3. Wear and corrosion resistance

Forged steel materials such as A105N and LF2 provide high hardness and durability. Combined with precision surface finishing, wear is significantly reduced during operation. It also performs well in corrosive environments when stainless steel variants are used.

✔️ 4. Quick operation and low pressure loss

A 90° quarter-turn mechanism allows fast opening/closing, while the full-bore design minimizes flow resistance and energy loss.

✔️ 5. Compact and space-saving design

Compared to cast steel valves, the forged structure is more compact and lightweight, making it suitable for confined installations such as ship systems and modular piping.

✔️ 6. Wide media compatibility

Suitable for various media including gas, water, oil, steam, and chemicals, even under high temperature and pressure conditions.
