Introducing the superior AOC-9031 Series Single Parallel Sliding Gate Valves, commonly referred to as flat gate valves, which play a pivotal role in your production process. These valves boast exceptional opening and closing capabilities, characterized by their full bore design that ensures minimal flow resistance and outstanding sealing performance. Effortlessly operable, they are meticulously engineered to excel in the transportation pipelines and storage facilities of refined oil products. Additionally, they are ideal for wellhead devices utilized in oil and natural gas extraction, as well as pipelines that handle media laden with suspended particles and fibers, ensuring efficiency and reliability at every turn.
The AOC-9032 Series Double Parallel Sliding Gate Valves redefine excellence as indispensable control valves in the production landscape. Distinguished by their ingenious metal contact structure, these valves promise unwavering reliability and an unparalleled cut-off performance. Perfectly suited for roles as emergency shut-off valves, vent valves, or large-diameter control valves, they thrive under the extremities of high-temperature, high-pressure, and ultra-low-temperature environments. Their versatile applications span across transportation pipelines and storage setups for refined oil products. They also find prominence in wellhead devices for oil and natural gas extraction, pipelines for media with suspended particles and fibers, independent steam turbine feed systems, and daunting scenarios involving high-temperature and high-pressure particles, delivering unmatched performance and peace of mind.

Non-guided Structure Features
1. This gate valve boasts a unique design without a guide hole, resulting in an exceptionally compact structure. Its sleek and lightweight nature makes it an ideal choice for modern applications.
2. The valve's gate comes with innovative design options such as V-shaped, semi-circular, and pentagonal channels. This provides exceptional control over the valve's regulating capabilities, allowing precise adjustment to any opening degree to meet diverse pipeline flow requirements (see the right diagram).
3. Engineered for durability, this valve incorporates floating valve seats with a soft-hard composite seal, ensuring extended service life. In cases of abnormal internal pressure rise, the floating valve seat smartly releases the excess pressure into the pipeline, guaranteeing safety and efficiency.
4. To tackle potential leakage issues, grease injection valves are strategically placed at the external seats of the valve body. In the event of seal pair wear, these allow for the easy injection of sealing grease, effectively preventing leakage and maintaining valve integrity.
5. At the bottom of the valve body lies a drain valve, meticulously designed for the efficient discharge of accumulated impurities, maintaining optimal valve function.
Guided Gate Structure Diagram
1. When fully open, the gate aligns its guide hole with the valve body channel, creating a seamless straight pipe section that facilitates direct media purging. This streamlined design enhances operational efficiency (see above diagram).
2. Throughout the gate's travel during opening or closing, continuous contact between the valve seat and gate is maintained. The soft valve seat functions as a self-cleaning mechanism, effortlessly scraping off impurities, making this flat gate valve perfect for handling media with suspended particles and fibers while protecting the seal surface from potential thermal deformation damage.
3. With floating valve seats featuring a soft-hard composite seal, the valve promises long-lasting performance and reliability.
4. In scenarios where valve cavity pressure rises unexpectedly, the innovative floating valve seat promptly releases the high pressure into the pipeline, ensuring operational safety.
5. Strategically placed at the base of the valve, a drain valve efficiently expels accumulated impurities, ensuring the valve's smooth operation and longevity.
