Non-guided Structure Features
1. This innovative gate valve boasts a non-guided design that eliminates the need for a guide hole, resulting in an impressively compact and lightweight structure. Its reduced size and weight make it an ideal choice for versatile applications.
2. Ingeniously engineered, the gate can be customized with V-shaped, semi-circular, or pentagonal channels. This versatility bestows the valve with unparalleled regulating capabilities, allowing precise adjustment to any opening degree to meet the varied flow requirements of pipeline systems (refer to the right diagram for detail).
3. The dual valve seats, crafted to float, feature a soft-hard composite seal that ensures longevity. In events of abnormal internal pressure build-up, these seats automatically release excess pressure, safeguarding the system and extending the valve's lifespan.
4. Equipped with grease injection valves positioned at the external seats on the valve body, this feature allows proactive maintenance. Should seal wear lead to potential leakage, sealing grease can be injected to instantly rectify and prevent valve leaks.
5. For ease of maintenance, a strategically placed drain valve at the valve body's base efficiently removes any accumulated impurities, ensuring optimal performance and reliability.
Guided Gate Structure Diagram
1. When fully opened, this valve's guide hole aligns flawlessly with the valve body channel, creating a seamless straight pipe section. This alignment facilitates direct and thorough media purging, as illustrated in the above diagram.
2. As the gate transitions between open and closed positions, the valve seat maintains continuous contact, effectively adapting to the gate. The soft seat design naturally scrapes off impurities, making this flat gate valve particularly advantageous for handling media with suspended particles and fibers, while also preventing damage from thermal deformation.
3. Designed with floating dual valve seats and a robust soft-hard composite seal, this configuration ensures extended operational life and reliability.
4. In scenarios of unexpected cavity pressure escalation, the floating valve seat adeptly releases excess pressure into the pipeline, maintaining system safety and integrity.
5. At the core of maintenance simplicity, a drain valve located at the valve body's base offers a practical solution for the expulsion of accumulated impurities, ensuring the valve remains clean and efficient.
