Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, commonly known as flat gate valves, a pivotal member of the control valve family that elevates your production process to the next level. These exceptional valves boast superior opening and closing capabilities, a full bore design, minimal flow resistance, remarkable sealing integrity, and effortless operation. Tailored for optimal performance in transportation pipelines and storage facilities for refined oil products, wellhead systems for oil and natural gas extraction, and pipelines tasked with managing media infused with suspended particles and fibers, these valves deliver unmatched reliability and efficiency.
Unveiling the AOC-9032 Series Double Parallel Sliding Gate Valves, an essential component in the realm of control valves, dedicated to enhancing production processes. With an innovative metal contact structure, these valves promise dependable functionality and outstanding cut-off performance. Ideal for critical applications such as emergency shut-off valves, vent valves, and large-diameter control valves, even under severe high-temperature, high-pressure, and ultra-low-temperature scenarios. From refined oil product transportation and storage systems to wellhead devices for oil and natural gas extraction, as well as pipelines handling media with suspended particles and fibers, these valves excel. They also shine in independent steam turbine feed systems and in contending with harsh conditions defined by high-temperature and high-pressure particles.

Non-guided Structure Features
1. The innovative gate design eliminates the need for a guide hole, resulting in a streamlined, compact structure that's both lightweight and efficient. This enhancement contributes to the valve's sleek profile and ease of installation.
2. The gate's versatile design can accommodate V-shaped, semi-circular, or pentagonal channels. This flexibility imparts the valve with exceptional regulating capabilities, allowing precise adjustments to any degree of opening, fully satisfying the dynamic flow requirements of pipeline systems (as illustrated in the accompanying diagram).
3. Featuring dual floating valve seats with a unique soft-hard composite seal, this design ensures exceptional durability and longevity. In the event of an unexpected rise in internal cavity pressure, the intelligently engineered floating valve seat automatically releases the excess pressure back into the pipeline, maintaining optimal operational conditions.
4. To address potential leakages, the valve body is equipped with grease injection valves at its external seats. Should there be any wear-induced leaks, injecting sealing grease at these points effectively prevents further leakage, ensuring seamless operation.
5. Strategically placed at the valve body's base, a drain valve facilitates the efficient discharge of any accumulated impurities, maintaining the valve's pristine condition and functionality.
Guided Gate Structure Diagram
1. When fully opened, the gate's guide hole aligns perfectly with the valve body channel, transforming it into a seamless straight pipe section. This alignment allows for unhindered direct media purging, as depicted in the above diagram.
2. Throughout the gate's travel-whether opening or closing-the valve seat maintains consistent contact and alignment with the gate. This synergy ensures that the soft valve seat effectively scrapes away impurities, making this flat gate valve ideal for media containing suspended particles and fibers. It also safeguards the seal surface against potential damage due to thermal deformation of the valve body.
3. Equipped with dual floating valve seats that feature a durable soft-hard composite seal, this design guarantees a longer operational lifespan and reliability.
4. In instances where valve cavity pressure surges unexpectedly, the floating valve seat automatically intervenes to release the excess pressure back into the pipeline, ensuring safety and efficiency.
5. Situated at the valve body's base, a drain valve is adeptly designed to discharge any accumulated impurities, thus preserving the valve's efficiency and integrity.
