Product Introduction of Micro Resistance Slow Closing Butterfly Check Valve

HH48/49X micro resistance slow closing butterfly check valveThe letter code HH48/49, 4 represents flange type, X represents soft seal, mainly used to prevent fluid backflow and large liquid backflow in pipeline systems. The micro resistance slow closing butterfly check valve has the characteristics of novel structure, small volume, small weight, low flow resistance, reliable sealing, stable opening and closing, good wear resistance, long service life, and slow closing not affected by the medium, which has good energy-saving effect.

Application scope of micro resistance slow closing butterfly check valve

Micro resistance slow closing butterfly check valve can prevent medium backflow and effectively limit destructive water hammer in water supply and drainage pipelines for clean water, sewage, seawater and other media, ensuring the normal use of the pipeline. Widely promoted and applied in industries such as industry and urban construction, with good response, but not suitable for media containing solid particles and high viscosity.

Structure and working principle of micro resistance slow closing butterfly check valve

HH48/49X micro resistance slow closing butterfly check valveIt mainly consists of a valve body, two semi-circular valve discs, a return spring, and a needle valve (micro adjustment valve).

Mainly relying on the thrust of the imported medium, the two valves were smoothly pushed open. When the inlet medium pressure drops below the outlet pressure, the medium will reflux, and the valve disc will automatically close under the action of the spring and medium reflux

Micro resistance slow closing butterfly check valve has the following 5 advantages:

1. Butterfly plate structure:HH48/49X micro resistance slow closing butterfly check valveAdopting a butterfly plate structure can reduce resistance and improve the efficiency and stability of pipeline flow compared to traditional gate valves and globe valves.

2. Low resistance characteristics: This type of valve adopts a butterfly plate structure, which has much lower resistance compared to the valve disc in other types of valves. It can effectively reduce the pressure drop and fluid energy consumption of the pipeline system, improve system efficiency, and reduce system operating costs.

3. Slow closing design: The micro resistance slow closing butterfly check valve adopts a slow closing design, which can effectively reduce the water hammer phenomenon when the fluid is closed, reduce pipeline vibration and noise, and extend the service life of the equipment.

4. Bidirectional sealing: The micro resistance slow closing butterfly check valve adopts bidirectional sealing, which effectively protects against fluid backflow in the pipeline system and has excellent sealing performance, making it reliable when applied in liquid transportation pipelines.

5. Good corrosion resistance: Micro resistance slow closing butterfly check valves often use corrosion-resistant materials, which have good corrosion resistance, can adapt to the transportation of various fluids, and enhance the stability and service life of the equipment.

In conclusion,HH48/49X micro resistance slow closing butterfly check valveIt has the advantages of low resistance, flexible operation, slow closing design, bidirectional sealing, and good corrosion resistance, and has a wide range of application prospects in industrial control applications.
