Describe
Q(3/6/9)47HF High Pressure Forged Steel Ball Valve Product Overview
 
use
 
Applicable to: chemical, petroleum, natural gas, metallurgy, and other industries and natural gas long-distance pipelines containing hydrogen sulfide medium, many impurities, and severe corrosion
 
Features
 
All parts of the forged steel fixed ball valve series are all forged. The overall structure of the valve is compact, small in size and good in steel. It is suitable for high pressure and large diameter pipelines. The valve seat adopts spring-cut active structure and can be customized according to customers. It is required to be designed as a two-way inlet seal, one-way inlet and outlet at the same time, and the pressure cross-sectional area of ​​the valve seat is precisely calculated to ensure that the valve can be opened and closed under high pressure conditions; the self-contained discharge valve is used to raise the cavity in the valve body unexpectedly. When pressing, the valve can be effectively ensured; the valve shaft adopts anti-blowing protection structure, three sealing measures; the bearing with low friction coefficient, the valve stem and the valve body have no contact, which is convenient for the valve to open and close.
