1PC,2PC,3PC Ball Valve

1PC/2PC/3PC Ball Valve is a ball valve classified according to the structure of valve body disassembly. It is opened and closed by rotating the ball body, and the specifications are distinguished according to the number of valve body components to adapt to different installation and maintenance needs.Widely used in industries such as petrochemicals, water supply and drainage, gas transportation, pharmaceuticals, etc., to control water, oil products, gas, corrosive media, and adapt to low to medium high pressure pipeline connection and disconnection scenarios.

Common Types

  • 1PC ball valve: The valve body is cast in one piece, with a compact structure, suitable for low-pressure small caliber and maintenance free working conditions
  • 2PC ball valve: The valve body is connected in two sections with bolts, making it easy to disassemble and assemble. It is suitable for scenarios with medium and low pressure and routine maintenance needs
  • 3PC ball valve: The valve body is connected by three flange sections, and the valve seat and core can be disassembled online, suitable for high-pressure and frequent maintenance conditions

Structural Advantages & Corresponding Benefits

  1. Segmented sealing structure

  • Special point: The 2PC/3PC valve seat is precisely adapted to the valve body, and the sealing surface comes with compensation function
  • Result:Sealed with zero leakage, strong pressure resistance, suitable for medium and high pressure medium transportation

  1. Modular disassembly and assembly structure

  • Special point: 3PC valve body three-stage design, valve seat and core can be disassembled and replaced separately
  • Result:  Low maintenance cost, no need to disassemble pipelines, suitable for frequent maintenance conditions
