Spec Sheet: HW-BB Forging Fully Welded Trunnion Mounted Ball valveTrunnion ball valve ZD

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 a trunnion-mounted ball, fully forged metal parts, and a fully welded body design. The forging body ensures the quality of ball valve parts and welded body provides the shell strength and rigidity, while completely eliminating the possibility of medium leakage. The seat seal design uses a unique two-level soft seal and metal-to-metal seal to form triple sealing; the design of the seat piston is accurately calculated to ensure seal reliability with small open/close torque and easy operation.
