U.S. standard shrinkage fixed ball valve

Product overview: 

 The national standard fixed ball valve is designed for fire prevention, anti-static and anti-flying of the valve stem. It can design and manufacture DBB, DIB, DIB-2 and other functions according to different working conditions. It has good sealing performance and longer service life. There are two structures: support plate type and fixed shaft type. The flow channel shrinkage can reduce the fluid passing capacity inside the valve, reduce the deformation of ball valve parts, and prolong the service life of the ball valve. 

 Pressure range: PN16~PN100, 150LB~600LB 

 Caliber range: DN50~DN350
