Non-guided Structure Features
1. Revel in the ingeniously designed gate, free from guide holes, that provides a sleek, compact structure. This design results in a valve that is not only small in size and lightweight but remarkably efficient.
2. Embrace the dynamic adaptability of the gate, masterfully crafted to feature V-shaped, semi-circular, or pentagonal channels. This design grants the valve superior regulating capabilities, effortlessly adjusting to any degree of opening to fulfill the intricate flow requirements of sophisticated pipeline systems (as illustrated in the accompanying diagram).
3. Discover the innovation of dual floating valve seats integrated with a soft-hard composite seal, delivering exceptional longevity. In the event of an unexpected pressure surge within the valve cavity, the intelligent floating valve seat instinctively releases excessive pressure back into the pipeline, ensuring seamless operation.
4. Equipped with grease injection valves strategically positioned at the external seats of the valve body, this feature transforms maintenance by allowing sealing grease to be injected, effectively countering any leakage arising from seal wear, thus safeguarding the integrity of the valve.
5. Enhance operational reliability with a conveniently located drain valve at the bottom of the valve body, designed to efficiently expel any accumulated impurities within the valve, ensuring flawless performance.
Guided Gate Structure Diagram
1. Experience superior functionality when the valve is entirely open: the gate's guide hole aligns harmoniously with the valve body channel, creating a seamless straight pipe section that facilitates direct media purging (refer to the above diagram).
2. Witness the brilliance of perpetual contact; during the gate's transitional movements, the valve seat consistently maintains contact with the gate. The innovative soft valve seat skillfully scrapes away impurities, optimizing the flat gate valve for media containing suspended particles and fibers, while protecting the seal surfaces from potential damage due to thermal deformation of the valve body.
3. Delight in the smart engineering of dual floating valve seats with a soft-hard composite seal, designed to ensure exceptional durability and reliability.
4. In the event of abnormal pressure escalation within the valve cavity, the floating valve seat acts with precision, automatically releasing the excess pressure into the pipeline, thus maintaining optimal performance.
5. The thoughtfully included drain valve at the valve body's base provides an efficient outlet for discharging accumulated impurities, thus preserving the valve's peak performance.
