Features:
- It is made of carbon steel seamless steel pipe pressed and formed integral welded ball valve, which can withstand frequent operation in the presence of impurities and chemicals, and has a long service life.
- The valve is compact, lightweight,extension stem also easy to keep warm and install.
- Adopts carbon-strengthened PTFE inclined elastic sealing ring with negative pressure on the spherical surface, zero leakage and long service life.
- The stem uses two “O” rings, allowing the stem to rotate freely and seal tightly.
