Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, a cornerstone of precision engineering in the realm of control valves. Also known as flat gate valves, these marvels of innovation boast superior opening and closing characteristics. Revel in the advantages of a full bore, which translates to remarkably low flow resistance and impeccable sealing performance. Effortless operation is at your fingertips. These valves are perfectly crafted for the transportation pipelines and storage facilities of refined oil products, as well as wellhead devices for oil and natural gas extraction. Designed to excel in pipelines carrying media with suspended particles and fibers, the AOC-9031 Series represents the pinnacle of efficiency and reliability.
Presenting the AOC-9032 Series Double Parallel Sliding Gate Valves, another pivotal player in the efficient management of production processes. These valves feature an ingenious metal contact structure, ensuring dependable operation coupled with exceptional cut-off performance. The AOC-9032 Series excels as emergency shut-off valves, vent valves, and large-diameter control valves, even under extreme conditions, be it high-temperature, high-pressure, or extremely low-temperature environments. These valves find their calling in the transportation pipelines and storage units for refined oil products, wellhead devices for oil and natural gas extraction, and in pipelines dealing with suspended particles and fibers. Furthermore, they are indispensable for independent steam turbine feed systems and challenging scenarios involving high-temperature and high-pressure particles.

Non-guided Structure Features
1. The innovative gate design eliminates the need for a guide hole, producing a valve with a remarkably compact structure. This results in a smaller size and reduced weight, making it effortless to integrate and handle.
2. With the ability to design the gate with V-shaped, semi-circular, or pentagonal channels, this valve offers exceptional regulating capabilities. It adapts seamlessly to any opening degree, fulfilling the diverse flow requirements of pipeline systems (see the right diagram).
3. The dual valve seats are engineered to float and feature a robust soft-hard composite seal, guaranteeing an impressively long service life. Should the valve's internal cavity pressure surge unexpectedly, the floating valve seat cleverly releases excess pressure back into the pipeline, maintaining system safety.
4. Equipped with grease injection valves at the outer seats of the valve body, this design allows for immediate intervention in case of leakage due to seal wear. Injecting sealing grease halts leakage efficiently, ensuring continuous operation without downtime.
5. A strategically placed drain valve at the bottom of the valve body efficiently expels any accumulated impurities within the valve, maintaining optimal performance.
Guided Gate Structure Diagram
1. When fully open, the gate's guide hole aligns perfectly with the valve body channel, creating a straight pipe section. This alignment allows for direct media purging, ensuring that the system remains clean and efficient (see above diagram).
2. During the gate's operational movement, the valve seat maintains consistent contact with the gate. The soft seat is specially designed to automatically clean impurities from the gate, making the flat gate valve ideal for mediums containing suspended particles and fibers, while protecting the seal surface from thermal damage.
3. Featuring floating dual valve seats with a durable soft-hard composite seal, this design promises a long-lasting operational life.
4. In scenarios where the valve cavity pressure rises unexpectedly, the floating valve seat autonomously releases high pressure back into the pipeline, safeguarding system integrity.
5. A drain valve located at the valve body's base ensures accumulated impurities are efficiently discharged, maintaining the valve's peak performance.
