Square three-way threaded ball valve

A square three-way threaded ball valve is a type of industrial valve that is designed for applications where the flow direction needs to be diverted or combined within a piping system. It features a ball with a hollow center and three ports, allowing for the flow to be directed to two of the ports while the third is closed off, or for the flow from two ports to combine into one. The unique feature of this valve is its square body design, which provides a robust and stable structure.

1. Structural Design


The square - body three - way threaded ball valve features a compact, cube - shaped structure. Its threaded connections ensure easy installation in pipeline systems. Made of stainless steel (as shown in the image), it offers good corrosion resistance. The precision - machined ball core inside enables flexible diversion, mixing, or shut - off of media, meeting complex flow - control needs.


2. Core Function


It is mainly used to control the direction and flow of media in pipelines. With three threaded ports, it can switch the flow direction of media, realize the confluence or diversion of media, and is suitable for industrial systems such as chemical, petroleum, and water treatment to efficiently manage multi - path fluid transmission.


3. Technical Specifications


Item Details
Body Material Stainless Steel (e.g., 304, 316)
Nominal Diameter 1/2" - 2" (Common Sizes, e.g., DN15 - DN50)
Pressure Rating PN16 - PN40 (Adapting to Pipeline Pressures)
Temperature Range - 20℃ - 200℃ (Suitable for Common Industrial Media)

4. Application Scenarios


Widely used in chemical production lines for medium diversion and mixing, petroleum pipelines for flow - direction adjustment, and water - treatment systems for media distribution. Its compact structure and reliable sealing make it suitable for occasions with limited installation space and strict control requirements.


5. Compliance & Quality


Designed in line with relevant industrial valve standards (e.g., GB/T for threaded ball valves in China). Undergoes strict factory tests, including pressure tests, leakage tests, and thread - connection reliability tests. The stainless - steel material has traceability to ensure compliance with quality and safety requirements in industrial applications.
