Forged steel float/ear ball valves are designed for reliable medium isolation under harsh conditions in industrial pipelines. The valve features a floating or ear-type ball design, offering smooth flow control and high precision while maintaining minimal torque. Its robust forged steel structure ensures elasticity under high pressure, and the valve design minimizes leakage risk by providing a tight seal.
● Floating/Trunnion Ball Design: Provides smooth operation and control, the float or rotary ball mechanism is adapted to the flow of the medium, achieving reliable isolation and flow control.
● Flange Connection:The flange connection is designed to facilitate installation, safely integrate into the piping system, and simplify maintenance and repair.
