Features:

  1. It is made of carbon steel seamless steel pipe pressed and formed integral welded ball valve, can withstand frequent operation in the presence of impurities and chemicals, and has a long life.
  2. The valve is compact, lightweight, easy to keep warm and install
  3. The seal adopts carbon-strengthened PTFE inclined elastic sealing ring with negative pressure on the spherical surface, zero leakage and long service life.
  4. The stem uses two “O” rings to allow the stem to rotate freely and seal tightly.
  5. The fully welded ball valve stem can be lengthened for easy insulation.
