Overview:
HW-BB type ball valve is widely used in oil, nature gas pipeline and the industries of liquefied gas, coal gas, etc. as an open/close control valve. The valve uses trunnion mounted ball, fully forged metal parts, fully welded body design. The forging body ensures the quality of ball valve parts and welded body ensures the shell strength and rigidity, while eliminates thoroughly the possibility of medium leakage. The design of seat seal uses unique two-level soft seal and metal to metal seal to form triple sealing; the design os seat piston is accurately calculated to ensure seal reliability with small open/close torque and easy operation. So it is safe and reliable to use this series of ball valve.
