Butterfly, ball, gate, globe and control valves are the five most widely used valves in industrial fluid control systems. Each features unique structures and dedicated application scenarios, supporting efficient and stable operation of fluid pipelines.

1. Butterfly Valve

Principle: A disc-shaped plate rotates around its axis to adjust flow opening.

Function: Flow shut-off and proportional regulation, ideal for large-flow pipelines.

Pros: Compact, lightweight, low-cost, easy maintenance, fast operation, low flow resistance.

Cons: Limited sealing pressure; not ideal for high pressure differential conditions.

2. Ball Valve

Principle: A perforated ball rotates 90° for quick full-open or full-close control.

Function: Rapid fluid shut-off/connection; V-type models support flow regulation.

Pros: Fast operation, low flow resistance, excellent sealing, bi-directional flow, 3-way design available for diversion.

Cons: Limited precision regulation; soft-seal types restricted by temperature and medium properties.

3. Gate Valve

Principle: A lifting gate opens or blocks the straight flow passage.

Function: Full-open or full-close shut-off only, no flow regulation.

Pros: Extremely low flow resistance, zero pressure loss, strong sealing, suitable for high temperature and pressure.

Cons: Slow operation, easy vibration and seal wear at partial opening.

4. Globe Valve

Principle: A disc moves vertically to cut off fluid via tight seat contact.

Function: Reliable fluid shut-off.

Pros: Great sealing, simple maintenance.

Cons: High flow resistance, unsuitable for particle-containing media, no precise regulation.

5. Control Valve

Principle: Actuator receives control signals to adjust flow area automatically.

Function: Precise, automatic regulation of flow, pressure and temperature.

Pros: High automation, remote control, fast response, wide adaptability for complex working conditions.

Cons: High cost, complex structure, higher maintenance requirements.
