Ball Valve Flange Type Features and Benefits

The flange type ball valve is a new type of valve and that is widely used. This ball valve full bore has the following advantages:

1. The fluid resistance is small, and its resistance coefficient is equal to that of the same length pipe.

2. Sealing performance is good, flange type ball valve's seat widely uses plastics, such as PTFE, RPTFE, NYLON, PEEK. and flange type ball valve has been widely used in vacuum systems.

3. It is easy to operate and can open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

4. It is easy to maintain, the structure of flanged type ball valve is simple, Sealing ring generally is movable, easy to disassemble and replace

Ball Valve Classification

Flange type ball valve with iso5211 has many different types. Classified by ball structure, there are floating ball valves, fixed ball valves, and elastic ball valves. 

Classified by body structure, there is a 1pc ball valve, 2pc ball valve, and 3pc ball valve. 

Classified by material, there are iron ball valve, WCB ball valve & stainless steel ball valve.

Regarding the pressure, as per different manufacturing standards, there are PN1.0-32.0MPa、ANSI CLASS 150-900、JIS10-20K. 

About the operation, there are a handle lever, worm gear, pneumatic actuator, electric actuator, hydraulic, etc.

Ball Valve Flange Type FAQs

Q What Are Ball Valves Used For?

The flange type ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline.

Q Can Flange Type Ball Valves Be Used for Isolation?

Yes, a flange type ball valve can be used for isolation.

Q What is a Floating Ball Valve?

Its ball is floating. under medium pressure, the ball can move and tightly press on the sealing surface of the outlet end to ensure that the outlet end is sealed. The floating ball valve has a simple structure and good sealing performance, but the outlet sealing ring bears all the working medium pressure, so it is necessary to consider whether the outlet sealing can withstand all the pressure or not. This structure flange type ball valve is widely used in low and medium pressure.
