🔩 What is a Ball Valve?

A ball valve is a quarter-turn shut-off valve that uses a rotating spherical ball with a hole (bore) to control flow.

• Handle parallel → OPEN

• Handle perpendicular → CLOSED

✔ Fast operation (90° turn)
✔ Tight sealing
✔ Low pressure drop
✔ Used for water, oil, gas, steam, chemicals

🧩 Types of Ball Valves (with Technical Details)

1. Floating Ball Valve

⚙️ Technical Details

• Ball is not fixed; it “floats” slightly

• Pressure pushes ball into seat for sealing

• Suitable for low to medium pressure

📊 Specification

• Size: 15 mm – 300 mm (½”–12”)

• Pressure: Class 150–600

• Material: SS304 / SS316 / Carbon Steel

• End: Threaded / Flanged / Welded

📌 Applications

Water lines, chemical plants, HVAC systems

💰 Price (India): ₹800 – ₹8,000 / piece (small to medium sizes)

---

2. Trunnion Mounted Ball Valve

⚙️ Technical Details

• Ball is fixed with top & bottom shafts (trunnions)

• Seats move toward ball (spring loaded)

• Very low operating torque

📊 Specification

• Size: 50 mm – 1200 mm+

• Pressure: Class 150 – 2500

• Material: Forged steel / SS / Duplex steel

• Design: Fire-safe, anti-static

📌 Applications

Oil & gas pipelines, refineries, high-pressure systems

💰 Price: ₹10,000 – ₹5,00,000+ depending on size/class

3. 2-Way Ball Valve (Standard Ball Valve)

⚙️ Technical Details

• One inlet, one outlet

• Simple ON/OFF control

• Full bore or reduced bore

📊 Specification

• Size: 15 mm – 200 mm

• Pressure: PN16 – PN40 / Class 150–300

• Operation: Manual / Pneumatic / Electric

💰 Price: ₹300 – ₹5,000

---

4. 3-Way Ball Valve

⚙️ Technical Details

• Has 3 ports (L-port or T-port)

• Used for mixing or diverting flow

📊 Specification

• Size: 15 mm – 150 mm

• Pressure: PN16 – PN40

• Material: SS / Brass / PVC

💰 Price: ₹1,500 – ₹25,000

---

5. V-Port Ball Valve (Control Valve Type)

⚙️ Technical Details

• Ball has V-shaped notch

• Allows flow control (not just ON/OFF)

• High precision throttling

📊 Specification

• Size: 15 mm – 200 mm

• Control: Pneumatic actuator mostly

• Accuracy: High flow modulation

💰 Price: ₹8,000 – ₹1,50,000
