Product Description
Product Description
Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves - a pinnacle of engineering excellence in the realm of control valves. Also known in the industry as flat gate valves, these crucial components boast superb opening and closing capabilities that are second to none. Revel in the benefits of a full bore design that ensures minimal flow resistance, alongside a sealing performance that's both impeccable and reliable. Operating these valves is a breeze, making them the go-to choice for multiple applications. Whether you are dealing with the transportation pipelines and storage facilities of refined oil products or managing wellhead devices in the extraction of oil and natural gas, these valves rise to the occasion. They also excel in handling pipelines carrying media with suspended particles and fibers, ensuring smooth and efficient operation.
The AOC-9032 Series Double Parallel Sliding Gate Valves elevate the standards of control valves, incorporating a distinctive metal contact structure that guarantees operational reliability and unparalleled cut-off performance. These valves are indispensable in scenarios demanding emergency shut-off, ventilation control, or managing large-diameter flow control under extreme conditions such as high temperature, high pressure, and extremely low temperatures. Their versatility extends to an array of applications, including refined oil product transport and storage, wellhead devices for oil and natural gas extraction, and pipelines handling media with suspended particles and fibers. Additionally, they are integral to independent steam turbine feed systems and other high-stakes environments marked by high-temperature, high-pressure particles, showcasing their adaptability and resilience in the face of demanding operational challenges.Product Parameters

Structural Features
Non-guided Structure Features
1. The gate's innovative design, lacking a guide hole, offers an impressively compact structure, resulting in a valve that is not only small in size but also incredibly lightweight.
2. With the versatility to design gates in V-shaped, semi-circular, or pentagonal channels, this valve demonstrates exceptional regulating capabilities. It allows for precise adjustments to any opening degree, efficiently meeting the diverse flow requirements of pipeline systems (see the right diagram).
3. Engineered with two floating valve seats featuring a durable soft-hard composite seal, this valve promises extended longevity. In the event of abnormal internal cavity pressure spikes, the floating valve seat acts swiftly to automatically release the excess pressure into the pipeline, ensuring optimal operation and safety.
4. Equipped with grease injection valves at the external seats of the valve body, this design provides an easy solution for maintenance. Should leakage arise from seal pair wear, the injection of sealing grease effectively stops further leakage, enhancing the valve's reliability and longevity.
5. A strategically placed drain valve at the valve body's bottom efficiently expels accumulated impurities, maintaining the valve's integrity and performance.
Guided Gate Structure Diagram 1. In the fully open position, the gate's guide hole perfectly aligns with the valve body channel, transforming it into a seamless straight pipe section. This design allows for the unhindered passage of media, facilitating direct purging as depicted in the above diagram.
2. During the gate's operational journey of opening or closing, the valve seat maintains constant contact and fit with the gate. The soft valve seat's ability to automatically scrape away impurities ensures that the flat gate valve is highly suitable for media containing suspended particles and fibers, while also safeguarding the seal surface from potential thermal-induced deformation damage.
3. Engineered with two floating valve seats and a robust soft-hard composite seal, this valve promises enduring performance and longevity.
4. In instances of abnormal pressure rise within the valve cavity, the floating valve seat promptly responds by releasing the excess pressure into the pipeline, maintaining safe and efficient operation.
5. Strategically positioned, the drain valve at the valve body's bottom ensures the efficient discharge of accumulated impurities, preserving the valve's functionality and longevity.
