Introducing the highly advanced AOC-9031 Series Single Parallel Sliding Gate Valves, also popularly termed as flat gate valves. These valves stand out as one of the cornerstone control valves in modern production processes. Renowned for their superior opening and closing dynamics, they boast a full bore design for optimal flow, minimal flow resistance, and exceptional sealing capabilities, all while ensuring effortless operation. These versatile valves are impeccably designed for use in transportation pipelines and storage systems of refined petroleum products. They are indispensable for wellhead devices in oil and natural gas extraction, and ideal for media pipelines containing suspended particles and fibers. Experience efficiency and reliability like never before with these expertly engineered solutions.
Delving into the realm of precision, the AOC-9032 Series Double Parallel Sliding Gate Valves emerge as another essential category of control valves in the production landscape. These cutting-edge valves feature an innovative metal contact structure that guarantees steadfast performance and unparalleled cut-off capabilities. They are meticulously crafted for deployment in emergency shut-off scenarios, vent valves, or as large-diameter control valves, even under the most challenging conditions such as high temperatures, extreme pressures, and ultra-low temperature environments. Their applications extend across transportation pipelines and storage facilities for refined oil products, vital wellhead devices for oil and gas extraction, media pipelines with suspended particles and fibers, individual steam turbine feed systems, and environments characterized by high-temperature and high-pressure particulate conditions. Rely on this robust solution for all your demanding operational needs.

Non-guided Structure Features
1. The innovative gate design lacks a guide hole, resulting in an impressively compact structure with reduced size and weight, making the valve extraordinarily lightweight yet robust.
2. The gate offers versatile design options including V-shaped, semi-circular, or pentagonal channels, empowering the valve with dynamic regulating capabilities. This flexibility allows precise adjustments to any opening degree, perfectly meeting diverse flow requirements of pipeline systems (refer to the accompanying diagram).
3. Engineered for longevity, the floating dual valve seats feature a soft-hard composite seal. This construction ensures a durable performance, as the seats can automatically release excessive internal cavity pressure back into the pipeline, safeguarding the system from abnormal pressure spikes.
4. To address potential leakages, external grease injection valves are integrated into the valve body. In scenarios of seal pair wear-induced leakage, these valves allow for the injection of sealing grease, effectively preventing further valve leakage.
5. For effective maintenance, a strategically placed drain valve at the bottom of the valve body enables the discharge of accumulated impurities, keeping the valve in optimal condition.
Guided Gate Structure Diagram
1. When fully open, the guide hole in the gate aligns seamlessly with the valve body channel, forming a direct pipe section that facilitates unhindered media purging (as illustrated in the diagram above).
2. During the operation of opening or closing, the valve seat maintains constant contact with the gate. The soft valve seat is designed to automatically scrape off impurities from the gate, enhancing the valve's suitability for media containing suspended particles and fibers. This design also prevents damage to the seal surface caused by thermal deformation of the valve body.
3. Designed for extended service life, the floating valve seats combine soft-hard composite sealing, ensuring a reliable and long-lasting performance.
4. In cases of abnormal valve cavity pressure increase, the intelligent floating valve seat design allows for the automatic release of excess pressure back into the pipeline, thus maintaining system integrity.
5. For routine maintenance, a drain valve is strategically positioned at the bottom of the valve body, facilitating the removal of any accumulated impurities within the valve.
