Ball Valves Type

1. By Structure

• Floating Ball Valve:

• The ball is not fixed and can slightly move inside the valve body.

• Sealing is achieved by the fluid pressure pushing the ball against the downstream seat.

• Suitable for low to medium pressure applications, typically with smaller diameters.

• Trunnion Ball Valve:

• The ball is fixed by upper and lower trunnions, preventing movement.

• The seat moves to maintain sealing.

• Ideal for large diameter and high-pressure conditions, with lower operating torque.

• Eccentric Half-Ball Valve:

• Features a partially open ball with an eccentric design for opening and closing.

• Excellent sealing and suitable for media with particles or fibers.

• V-Port Ball Valve:

• The ball or seat has a V-shaped notch, allowing precise flow control.

• Provides good flow regulation and is often used in applications requiring flow adjustment.

2. By Port Design

• Two-Way Ball Valve:

• The simplest type with a single inlet and outlet, used for straightforward on/off control.

• Three-Way Ball Valve:

• L-Port: Switches flow direction between two different channels.

• T-Port: Allows connection of three channels, useful for mixing or diverting flow.

• Available in L-shaped and T-shaped flow paths:

• Four-Way Ball Valve:

• Typically used in complex flow path switching and multi-channel control scenarios.

3. By Connection Type

• Flanged Ball Valve:

• Connected to the pipeline using flanges.

• Suitable for large-diameter and high-pressure applications, offering easy installation and removal.

• Threaded Ball Valve:

• Uses threaded connections, mostly for small-diameter and low-pressure systems.

• Welded Ball Valve:

• Connected through welding, providing a leak-free and durable solution for permanent installations.

• Clamp Ball Valve:

• Commonly used in the food and pharmaceutical industries, designed for easy disassembly and cleaning.

4. By Actuation Method

• Manual Ball Valve:

• Operated manually with a handle or handwheel, suitable for simple and non-automated systems.

• Pneumatic Ball Valve:

• Driven by a pneumatic actuator, allowing fast on/off operations.

• Often integrated with automation systems.

• Electric Ball Valve:

• Operated by an electric actuator, enabling remote and automated control.

• Ideal for high-precision flow regulation and automated processes.

• Hydraulic Ball Valve:

• Powered by a hydraulic system, often used in high-pressure and large-diameter applications.

5. By Application

• High-Pressure Ball Valve:

• Designed for high-pressure environments with reinforced structure and special materials.

• Cryogenic Ball Valve:

• Suitable for low-temperature applications (e.g., LNG, liquid nitrogen systems).

• Constructed with materials that withstand brittle behavior at low temperatures.

• Sanitary Ball Valve:

• Used in food and pharmaceutical industries, made of stainless steel, and designed for easy cleaning.

• Control Ball Valve:

• Provides flow control capabilities, typically with a V-port design or smart actuator integration.
