Product Introduction

The orbit ball valve stem operates with a combination of rotation and lifting motion.
High pressure of 2500 LB results in significant torque.
Customers require low torque, excellent high-pressure sealing, and reliable performance under alternating high and low temperatures.
To meet these requirements, we have adopted an upper and lower V-shaped structure to reduce friction while ensuring sufficient sealing stress.
The graphite material has been specially reinforced to maintain higher strength and buffering characteristics.
