I. Core Structural Features

This product is a SK2002 ball valve ,The structure conforms to national standards such as "GB/T 12238 Flanged and Butt-welded Ball Valves" and "GB/T 7306 55° Sealing Pipe Threads". The core structural features are as follows:
  1. Internal and External Thread Connection Design :One end is an internal thread and the other end is an external thread (conforms to GB/T 7306), adapting to the connection needs of different pipe diameters or different interface forms, and is convenient and flexible to install.
  2. Butterfly Handle Operation :Equipped with a red butterfly handle, conforming to "GB/T 12222 Connection of Multi-turn Valve Actuators", with low operating torque. 90° rotation can complete opening and closing, suitable for frequent operation scenarios.
  3. Nickel-plated Brass Valve Body :The valve body adopts nickel-plated brass (H59) process (silver appearance), combining the high strength of brass and the corrosion resistance of the nickel plating, conforming to "GB/T 12225 General Valves Copper Alloy Castings Technical Conditions", suitable for long-term use with water and neutral liquids.
  4. Soft Sealing Structure :The valve seat uses elastic sealing materials such as EPDM, with excellent sealing performance, meeting the sealing test requirements of "GB/T 13927 Industrial Valves Pressure Test", ensuring zero leakage of the medium.
  5. Straight-through Flow Path :The flow path is designed to be straight-through, with low hydraulic resistance and low flow loss, suitable for systems with high flow requirements such as water supply and drainage and HVAC.
