What is the feature of Flange Ball Valves

Flange ball valves are a type of quarter-turn valve with flanged ends, commonly used in pipelines to control the flow of liquids or gases. Here are the key features of flange ball valves:

1. Flanged Ends

Easy Installation & Removal: Flanges provide secure, bolt-on connections to pipelines.

Standardized Dimensions: Typically conform to ANSI, DIN, or JIS standards for compatibility.

2. Quarter-Turn Operation

Fast Operation: Only a 90° turn is needed to open or close the valve.

Simple Mechanism: Operated manually, with a lever or by actuators (electric, pneumatic, or hydraulic).

3. Spherical Ball Element

Full Bore or Reduced Bore Options: Allows for minimal pressure drop and efficient flow control.

Sealing: The ball is usually polished and seats are made from soft materials (e.g., PTFE) for tight shutoff.

4. Robust Construction

Material Variety: Available in stainless steel, carbon steel, brass, or other alloys.

High Durability: Suitable for high pressure and temperature applications.

5. Excellent Sealing Performance

Bubble-tight Shutoff: Ideal for gas and fluid isolation.

Leak-proof Design: Especially effective with proper seat materials and precision machining.

6. Corrosion and Chemical Resistance

Materials and Coatings: Can be selected for compatibility with aggressive or corrosive media.

7. Pressure and Temperature Ratings

Wide Operating Range: Suitable for a variety of industrial environments (e.g., oil & gas, chemical, water treatment).

8. Maintenance-Friendly

Easy Disassembly: Flanged ends and floating or trunnion-mounted designs facilitate maintenance and replacement.
