Introducing the AOC-9031 Series Single Parallel Sliding Gate Valves, also affectionately known as flat gate valves. These remarkable control valves stand as a cornerstone in the realm of production processes, lauded for their superior performance. Boasting exceptional opening and closing capabilities, they feature a full bore design, which translates to minimal flow resistance, ensuring that your operations remain smooth and efficient. Their excellent sealing performance guarantees reliability, while the simplicity of operation makes them user-friendly. These valves are perfectly suited for the transport pipelines and storage facilities of refined oil products. They are an ideal choice for wellhead devices used in oil and natural gas extraction, as well as pipelines tasked with handling media that contain suspended particles and fibers. With the AOC-9031 Series, elevate your operational efficiency to new heights.
Presenting the AOC-9032 Series Double Parallel Sliding Gate Valves, another formidable player in the control valve domain. These valves are equipped with a groundbreaking metal contact structure, delivering unmatched reliability and cut-off performance of the highest order. They're expertly designed for use as emergency shut-off valves, vent valves, or as large-diameter control valves, even in the most challenging environments characterized by high temperatures, high pressures, or extreme low temperatures. Applications of these versatile valves extend across transportation pipelines and storage equipment for refined oil products, wellhead devices in oil and natural gas extraction, and pipelines dealing with media that harbor suspended particles and fibers. Furthermore, they are essential in independent steam turbine feed systems and other severe environments involving high-temperature and high-pressure particles. With the AOC-9032 Series, you gain a robust solution engineered to meet the demands of rigorous conditions.

Non-guided Structure Features
1. The gate is ingeniously designed without a guide hole, resulting in a marvelously compact structure, making the valve not only small in size but also incredibly lightweight.
2. The gate's innovative design can incorporate V-shaped, semi-circular, or pentagonal channels, transforming the valve into a regulating marvel. This design flexibility allows it to adapt seamlessly to any desired opening degree, satisfying the diverse flow requirements of pipeline systems with ease (see the right diagram).
3. Designed with durability in mind, the valve features two floating seats with a soft-hard composite seal, promising an extended service lifespan. In the event of an abnormal pressure surge within the valve's internal cavity, these seats instinctively release the excess pressure into the pipeline, safeguarding the system.
4. Ingeniously equipped with grease injection valves at the external seats of the valve body, this system allows for seamless sealing maintenance. Should leakage occur due to seal wear, simply inject sealing grease to efficiently prevent any valve leakage.
5. Strategically placed at the bottom of the valve body, a drain valve ensures that any accumulated impurities can be effortlessly discharged, maintaining optimal valve performance.
Guided Gate Structure Diagram
1. When the valve stands fully open, the guide hole in the gate aligns perfectly with the valve body channel, forming a straight, unobstructed pipe section. This allows for straightforward media purging, ensuring seamless operation (see above diagram).
2. During the gate's dynamic opening or closing journey, the valve seat maintains continuous contact with the gate. The soft valve seat is ingeniously capable of automatically cleaning impurities off the gate during operation, making the flat gate valve an ideal choice for handling media with suspended particles and fibers. This also prevents any potential damage to the seal surface due to valve body thermal deformation.
3. The dual valve seats, renowned for their floating nature, boast a soft-hard composite seal to ensure a long-lasting service life.
4. In the rare event of a sudden pressure spike within the valve cavity, the floating valve seat automatically discharges the excess pressure into the pipeline, maintaining system equilibrium.
5. Strategically positioned at the base of the valve body, a drain valve facilitates the efficient removal of any accumulated impurities, enhancing operational reliability.
