The 500 Series ball valve is suitable for on-off control applications with low flow resistance and low pressure loss that have high requirements for shut-off class, and applications in which the media contain granular or fibrous substances.
In addition to having the features of easy shut-off and good rigidity of ball valves, the 50P Series eccentric rotary regulating ball valve also has the feature of large volume control of rotary control valves. The eccentric structure design can avoid the wear of the plug and seat to the utmost extent, providing high flowing capacity for gases, vapors, liquids, pulps, etc.
The 50V Series V-type regulating ball valve has a maximum adjustable ratio of 300:1. The one-piece body can ensure a solid and durable valve. The plug with the V-type cut and partially spherical surface is provided with excellent control function for the realization of stable control action in addition to shearing the materials.
The 50G Series pipeline ball valve is mainly used for the on-off function in the pipelines. The valve can realize double-direction sealing of metal seals through the compensation design structure in combination with special heat treatment processes. The maximum nominal pressure is ANSI 1500 LB. With a special trim structure, it can also be used for control applications.
The 50F Series floating ball valve adopts the split body and floating ball. It has various seal forms such as soft seals, hard seals, metal seals, etc.
