1.Classifying Ball Valves by Port Design
Full Port (Full Bore) Ball Valve
Features: The internal diameter matches the pipeline size, ensuring unobstructed flow.
Advantages:No pressure drop.Minimal turbulence and energy loss.
Reduced Port (Standard Bore) Ball Valve
Features: A smaller ball opening compared to the pipeline, causing some flow restriction.
Advantages:Economical and compact design.Suitable for moderate-flow applications.
One-Piece Ball Valve
Design: Single-body construction for durability and low leakage risk.
Benefits:Cost-effective and simple.
Two-Piece Ball Valve
Design: Divided into two parts for easier maintenance.
Benefits:Durable and versatile.
Three-Piece Ball Valve
Design: Three separable sections – two ends and a central body.
Benefits:Easy maintenance without disrupting pipeline connections.
2.Valve Types by Ball Support
Floating Ball Valve
Mechanism: The ball is held in place by valve seats and moves slightly to form a seal under pressure.
Benefits:Simple design and cost-effective.
Trunnion-Mounted Ball Valve
Mechanism: The ball is anchored by trunnions, allowing better control in high-pressure scenarios.
Benefits:Reduced torque and better sealing under high pressure.
3.Specialty Ball Valves for Unique Applications
V-Port Ball Valve
Features: A V-shaped ball or seat for precise flow control.
Advantages:Excellent for throttling and variable flow systems.
Multi-Port Ball Valve (3-Way, 4-Way)
Features: Designed to direct flow in multiple directions. T-port and L-port are the most common configurations.
Advantages:Reduces the need for multiple valves.
4.Types by Operation Method
Manual Ball Valve
Operated with a simple lever or handle.
Advantages: Affordable and easy to use.
Pneumatic Actuated Ball Valve
Uses compressed air for automated operation.
Advantages: Fast and reliable.
Electric Actuated Ball Valve
Operates via an electric motor for precise control.
Advantages: Ideal for remote monitoring and control.
5.Material Considerations for Ball Valves
Stainless Steel: Excellent for corrosive environments and high-pressure systems.
Brass: Economical and corrosion-resistant, ideal for water and gas.
PVC: Lightweight and cost-effective for low-pressure systems.
Carbon Steel: Durable and suitable for high-temperature applications.
