Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, a pivotal component in the realm of control valves for the production process. Renowned for their superior opening and closing capabilities, these flat gate valves boast remarkable features, including a full bore design, minimal flow resistance, exceptional sealing capabilities, and effortless operation. These valves are ideally suited for applications involving the transportation pipelines and storage systems of refined oil products, the precision wellhead devices for oil and natural gas extraction, as well as pipelines that handle media with suspended particles and fibers. With the AOC-9031 Series, you can trust in reliability and efficiency in your operations.
Discover the excellence of the AOC-9032 Series Double Parallel Sliding Gate Valves, another essential control valve series designed for the production process. These valves feature an innovative metal contact structure that ensures dependable operation and outstanding cut-off performance. Perfectly suited for use as emergency shut-off valves, vent valves, or large-diameter control valves, they perform exceptionally well under high-temperature, high-pressure, and extremely low-temperature conditions. Applications extend to the transportation pipelines and storage systems of refined oil products, wellhead devices for oil and natural gas extraction, and pipelines for media with suspended particles and fibers. Moreover, they serve independent steam turbine feed systems and thrive in challenging environments involving high-temperature and high-pressure conditions. Trust in the AOC-9032 Series for uncompromising performance in the most demanding scenarios.

Non-guided Structure Features
1. Ingeniously crafted without a guide hole, the gate boasts a compact structure, minimizing size and weight. This design innovation results in a lightweight valve that doesn't compromise on performance.
2. With versatile channel designs-V-shaped, semi-circular, or pentagonal-this valve offers exceptional regulating capabilities. It seamlessly adapts to various opening degrees, precisely meeting the flow demands of any pipeline system (see the right diagram).
3. Featuring dual floating valve seats with a robust soft-hard composite seal, this valve promises an extended service life. In the event of abnormal internal cavity pressure, the floating seat intelligently releases excess pressure back into the pipeline, ensuring safety and reliability.
4. Equipped with grease injection valves at the external seats, this innovative design allows for easy maintenance. Should seal pair wear lead to leakage, directly inject sealing grease to effectively prevent valve leakage, ensuring uninterrupted operation.
5. At the valve body's base, a strategically placed drain valve facilitates the expulsion of accumulated impurities, maintaining optimal valve performance and longevity.
Guided Gate Structure Diagram
1. When fully opened, the gate's guide hole aligns perfectly with the body channel, creating a straight pipe section for unobstructed media purging (see above diagram).
2. Throughout the gate's motion, the valve seat maintains constant contact, ensuring a snug fit. The soft seat acts as an automatic scraper, removing impurities from the gate. This design is ideal for handling media with suspended particles and fibers, while effectively safeguarding the seal surface from damage due to thermal deformation.
3. The dual floating valve seats, fortified with a soft-hard composite seal, guarantee a prolonged operational lifespan.
4. During abnormal pressure spikes within the valve cavity, the floating seat deftly releases excessive pressure into the pipeline, preserving the system's integrity.
5. The bottom of the valve body is fitted with a drain valve, which efficiently discharges internal impurities, ensuring sustained valve efficiency.
