Product Description
Product Description
Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, known also as flat gate valves, a pivotal element in the realm of control valves during the production process. Distinguished by their impeccable opening and closing capabilities, these valves boast a full bore design, ensuring minimal flow resistance and exceptional sealing performance. Their design translates into effortless operation, making them an ideal choice for an array of applications. These include the intricate transportation pipelines and storage units for refined oil products, wellhead equipment pivotal for oil and natural gas extraction, and the complex pipelines designed to handle media infused with suspended particles and fibers. With such a robust design, the AOC-9031 Series offers unmatched reliability and efficiency.
The AOC-9032 Series Double Parallel Sliding Gate Valves represent a significant advancement in control valve technology. Featuring a distinctive metal contact mechanism, these valves ensure unwavering reliability and superior cut-off capabilities, even under the most challenging conditions. Whether faced with high-temperature, high-pressure environments, or extremely low-temperature conditions, these valves excel as emergency shut-off units, vent valves, or large-diameter control solutions. Their versatility extends to a multitude of applications, including refined oil product pipelines, storage facilities, wellhead devices for oil and natural gas extraction, and media pipelines with suspended particles and fibers. Moreover, they are indispensable in independent steam turbine feed systems and are engineered to withstand the rigorous demands of high-temperature and high-pressure particle challenges, offering unparalleled performance and durability.Product Parameters

Structural Features
Non-guided Structure Features
1. The gate ingeniously dispenses with a guide hole, crafting a valve structure that is not only compact but also exceptionally lightweight. This results in a valve that is small in size yet big on efficiency.
2. The gate is versatile in design, offering V-shaped, semi-circular, or pentagonal channels. This grants the valve remarkable regulating capabilities, allowing it to adapt seamlessly to any opening degree and precisely meet the flow demands of diverse pipeline systems (see the right diagram).
3. With two floating valve seats featuring a soft-hard composite seal, this valve promises exceptional durability. Importantly, when the internal pressure escalates unexpectedly, the floating valve seat acts swiftly to release the pressure into the pipeline, ensuring safety and reliability.
4. Conveniently placed grease injection valves at the external seats of the valve body offer a practical solution. In the event of leakage due to seal wear, sealing grease can be injected here, effectively preventing valve leakage and maintaining optimal performance.
5. A strategically located drain valve at the bottom of the valve body is designed to efficiently discharge accumulated impurities, ensuring the valve remains clear and functional.
1. When fully opened, the guide hole in the gate aligns perfectly with the valve body channel, creating a seamless straight pipe section. This design facilitates direct media purging, enhancing operational efficiency (see above diagram).
2. Throughout the gate's movement, whether opening or closing, the valve seat maintains contact with the gate. The soft valve seat adeptly scrapes off impurities during operation, making the flat gate valve an ideal choice for media containing suspended particles and fibers. Simultaneously, it safeguards the seal surface from potential damage caused by thermal deformation of the valve body.
3. The dual floating valve seats with a soft-hard composite seal ensure outstanding durability and longevity.
4. Should the valve cavity pressure rise unexpectedly, the floating valve seat is engineered to automatically release this high pressure into the pipeline, enhancing system safety.
5. An efficiently designed drain valve is located at the valve body's bottom, providing a means to discharge any accumulated impurities, thus maintaining the valve's integrity and performance.
