Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, also known as flat gate valves, a standout in the realm of control valves within the production process. These valves boast superior opening and closing attributes, featuring a full bore design, which ensures minimal flow resistance. Their exceptional sealing performance and effortless operation make them indispensable for a variety of applications. Perfectly suited for the transportation pipelines and storage equipment of refined oil products, they also find their place in the wellhead devices crucial for oil and natural gas extraction. Additionally, they are expertly crafted to handle pipelines that transport media imbued with suspended particles and fibers. Discover the unmatched functionality that these valves bring to your industrial operations.
The AOC-9032 Series Double Parallel Sliding Gate Valves represent another essential category of control valves in the production landscape. These valves are engineered with a pioneering metal contact structure that guarantees steadfast reliability and delivers unparalleled cut-off performance. They are the ultimate choice for emergency shut-off valves, vent valves, or large-diameter control valves, specifically designed to thrive under high-temperature, high-pressure, and extremely low-temperature conditions. Their versatility extends to a range of applications including transportation pipelines and storage equipment for refined oil products, wellhead devices for oil and natural gas extraction, and pipelines carrying media with suspended particles and fibers. They are also ideal for independent steam turbine feed systems and excel in the most demanding conditions involving high-temperature and high-pressure particles. Elevate your industry's efficiency with these robust, double parallel sliding gate valves.

Non-guided Structure Features
1. The innovative design of our gate valve eliminates the need for a guide hole, resulting in a brilliantly compact, lightweight, and efficient structure.
2. Expertly crafted, the gate can be tailored with V-shaped, semi-circular, or pentagonal channels, offering unmatched regulating capabilities to accommodate any level of opening. This ensures seamless flow requirements for pipeline systems are met with precision (refer to the accompanying diagram for visual reference).
3. With two ingeniously floating valve seats featuring a soft-hard composite seal, durability is a promise. In instances of abnormal pressure escalation within the valve cavity, our floating valve seat design skillfully releases the pressure back into the pipeline, ensuring consistent performance.
4. For enhanced reliability, grease injection valves are strategically positioned at the external seats of the valve body. This feature allows for the injection of sealing grease in the event of leakage caused by seal wear, effectively preventing any potential valve leaks.
5. To maintain the purity of operations, a drain valve is aptly installed at the valve body's base, ensuring efficient expulsion of any accumulated impurities inside the valve.
Guided Gate Structure Diagram
1. When fully opened, the valve's guide hole aligns perfectly with the valve body channel to form a seamless straight pipe section, promoting direct and unobstructed media purging (refer to the diagram above for an illustration).
2. During the dynamic transition of the gate's opening or closing, the valve seat maintains a consistent contact fit with the gate. This innovative feature allows the soft valve seat to actively scrape away impurities, making our flat gate valve an ideal choice for media containing suspended particles and fibers, while also safeguarding the seal surface from damage due to thermal deformation.
3. Our dual floating valve seats, combined with a robust soft-hard composite seal, are engineered for longevity and dependable performance.
4. Our design ensures that in cases of abnormal pressure increases within the valve cavity, the floating valve seat skillfully releases the pressure back into the pipeline, maintaining system integrity.
5. At the core of our design, a drain valve is situated at the base of the valve body, specifically for the discharge of accumulated impurities, promoting a cleaner system.
