Contrasts Between O-Type and V-Type Ball Valves
O-Type Ball Valve Structure:
- Internally, the O-type ball valve has a ball with a central through-hole.
- The ball features a through-hole with a diameter equal to the pipe diameter.
- The ball can rotate within the sealing seat, with elastic rings on both sides of the pipeline to achieve sealing.
- Rotating the ball 90° changes the direction of the through-hole, facilitating valve opening and closing.
Advantages of O-Type Ball Valve:
- Minimal fluid resistance due to a low flow resistance coefficient.
- Swift and convenient operation with a 90-degree rotation.
- Excellent sealing performance using materials like polytetrafluoroethylene (PTFE).
- Long lifespan attributed to the self-lubricating properties of PTFE.
- High reliability with minimal risk of abrasion or wear on the sealing components.
V-Type Ball Valve Structure:
- The V-type ball valve features a ball core with a V-shaped structure.
- The valve core is a 1/4 spherical shell with a V-shaped notch for enhanced flow capacity and shearing capability.
- Particularly suitable for conditions involving fluid substances with fibrous characteristics.
- Generally designed as a single-sealing ball valve, less suitable for bidirectional use.
Advantages of V-Type Ball Valve:
- V-shaped edges effectively cut through impurities during ball rotation, providing a self-cleaning feature.
- Suitable for fluids with fibrous characteristics due to the V-shaped notch.
- The flange connection allows easy disassembly without the need for special tools.
- Low operating torque and high stability due to the use of low-friction materials.
- Ideal for proportional control with a wide range of adjustability.
In summary, O-type ball valves and V-type ball valves differ in their internal structures and applications. O-type valves excel in scenarios with minimal fluid resistance, reliable sealing, and a swift open-close mechanism. On the other hand, V-type valves are designed for applications involving fibrous substances, providing effective shearing and self-cleaning capabilities. Both types offer distinct advantages based on specific operational requirements.
