Overview:
HW-BB type ball valve is on /off control valve which uses trunnion mounted ball, forging body, bolted body design. The forging body ensures the quality, strength and rigidity of the valve body. The design and selection of bolted body is carefully and accurately calculated in order to ensure its rigidity, so it is safe to use this series of ball valves. The design of seat seal uses unique two-level soft seal and metal to metal seal to form triple sealing to ensure seal reliability with small open/close torque and easy operation. This type of valve is widely used in the nature gas and oil pipeline, the industries of petrochemical, medicine, city constructions, etc.
