Micro resistance slow closing butterfly check valve

Product overview:

This series of micro resistance slow closing butterfly check valves adopts a slanted disc large eccentricity design and a double eccentricity structure. At the same time, there is a graded buffer oil cylinder that can achieve two-stage closure, achieving the best effect of eliminating water hammer. Installed at the

outlet of the water pump can prevent destructive water hammer from occurring when the pump is stopped. Therefore, the valve can be widely used in municipal engineering. Water supply and drainage systems in industries such as power plants, metallurgy, and petrochemicals.

Product Features:

• Adopting a slanted disc large eccentricity design and a double eccentricity structure, the opening and closing dynamic performance is good, without the need for heavy hammers, and the energy-saving effect is significant.
• The slow closing device has a novel design and reliable performance. The valve closing time adopts a fast and slow two-stage design, which is suitable for different working conditions and reduces the impact of water hammer.
• The valve shaft adopts an inertia type, which is safe and reliable. At the rear end of the valve body, a valve disc axial adjustable mechanism is used, which has excellent sealing effect and adjustable zero leakage.
• The bearing of the valve shaft adopts a self-lubricating bearing, which has low friction resistance and does not require oil injection.
