Carbon Steel Butt Weld Precision Engineered Single Parallel Sliding Valves for Optimal Performance

    <sup>AOC-9031 Series Single Parallel Sliding Gate Valves (also known as flat gate valves) are one of the important types of control valves in the production process. Single Parallel Sliding Gate Valves have excellent opening and closing characteristics, featuring full bore, low flow resistance, good sealing performance, and easy operation. They are suitable for the transportation pipelines and storage equipment of refined oil products, wellhead devices for oil and natural gas extraction, and pipelines for media containing suspended particles and fibers.

AOC-9032 Series Double Parallel Sliding Gate Valves are also an important type of control valve in the production process. These valves adopt a unique metal contact structure, ensuring reliable operation and extremely high cut-off performance. They are widely used in emergency shut-off valves, vent valves, or large-diameter control valves under high-temperature, high-pressure, and extremely low-temperature conditions. Applications include transportation pipelines and storage equipment for refined oil products, wellhead devices for oil and natural gas extraction, pipelines for media containing suspended particles and fibers, independent steam turbine feed systems, and harsh conditions involving high-temperature and high-pressure particles.</sup>
