Valve Introduction
Fixed ball valves employ top-and-bottom shaft fixation, with ball rotation about the shaft axis for flow control. Line pressure does not displace the ball. Spring-energized seats keep the ball in constant contact, delivering consistent sealing under all pressures. Features include low torque, robust sealing, and long durability-suitable for oil, chemical,water treatment, and gas applications.
