Full-featured ultra-light control valve and control valve of the comparative advantage
The full-function ultra-light control valve is designed with nine advanced features, making it a highly versatile and efficient solution for various industrial applications. One of its key strengths lies in its excellent regulating function, which includes: ①favorable flow characteristics; ② high adjustable range (R = 100), ensuring precise control even at small openings; ③ superior small opening performance; ④ a high flow coefficient (Kv value), typically 2 to 3 times higher than that of single or double-seat valves and sleeve valves; and ⑤ fast adjustment speed. This makes it ideal for applications requiring accurate and responsive flow control.
In terms of shut-off performance, the full-function ultra-light control valve demonstrates exceptional sealing capabilities. Its standard leakage rate is significantly lower—up to 100 to 1000 times better than traditional single or double-seat valves and sleeve valves. This ensures minimal leakage and reliable operation under demanding conditions.
Another critical feature is its ability to handle pressure differentials effectively. Unlike conventional double-seat valves, which allow large pressure drops but suffer from higher leakage, or single-seat valves, which have low leakage but limited pressure tolerance, this valve successfully balances both aspects. It can maintain tight closure while handling high pressure, up to the rated PN value, ensuring safe and stable operation.
Corrosion resistance is also a standout feature. The valve is constructed using corrosion-resistant and erosion-resistant materials, along with protective measures to prevent damage from chemical attack, cavitation, and wear. This extends its service life and ensures long-term reliability in harsh environments.
The anti-blocking function is another advantage. Designed based on fluid dynamics principles, the valve has a streamlined internal flow path with minimal dead zones, reducing the risk of media settling or clogging. This makes it particularly suitable for applications involving high-viscosity fluids, suspensions, slurries, and particulate-laden media.
High compressive strength is essential for safety and durability. The valve’s body is built using a single-piece structure, enhancing its structural integrity and allowing it to withstand pressures up to 32 MPa or more. Additionally, a forged high-pressure design further improves its strength, making it suitable for high-stress environments.
Temperature adaptability is another key aspect. The valve incorporates a rigid-flexible sealing system that prevents thermal expansion issues, such as stem binding or leakage. High-temperature wear-resistant packing ensures reliable stem sealing even under extreme temperatures, maintaining performance in both high and low-temperature conditions.
Finally, the valve's compact, lightweight design makes it ideal for space-constrained applications. Its integrated body structure, optimized appearance, and direct connection to actuators result in a small footprint and reduced weight. For example, a DN100 electric valve weighs around 150 kg when using a sleeve control valve, but the full-function ultra-light control valve weighs only 40 kg (electronic version), representing a 73% reduction in weight. This not only simplifies installation and maintenance but also aligns with modern trends toward energy efficiency and compact instrumentation. Overall, the full-function ultra-light control valve combines performance, durability, and efficiency in a single, intelligent package.
