â… . Product Introduction
A silencing check valve is a type of automatic valve whose opening and closing parts rely entirely on the flow power of the medium to open or close, and its core function is to prevent the backflow of the medium. It is widely used in various pipeline systems to ensure the one-way flow of the medium and avoid equipment damage or system failure caused by backflow. Check valves are generally classified into four types: lift type, swing type, butterfly type and horizontal type. Among them, lift check valves should be installed on horizontal pipelines; vertical lift check valves and bottom valves are usually installed on vertical pipelines, and the medium flows from bottom to top; swing check valves have no restrictions on installation position, and are usually installed on horizontal pipelines, but can also be installed on vertical or inclined pipelines.
The HC41X energy-saving silencing check valve is a specialized type of silencing check valve, mainly suitable for water supply and drainage pipelines. Its valve disc adopts center axis guidance at the inlet end, ensuring flexible opening and closing, and it can be installed horizontally or vertically. Compared with ordinary check valves, it has the advantages of energy saving, silencing, and effective water hammer elimination, and is widely used in scenarios with high requirements for pipeline stability and noise control.
Note: The check valve only allows the medium to flow in one direction. Special attention should be paid to the flow direction of the medium during installation. The normal flow direction of the medium must be consistent with the arrow direction marked on the valve body, otherwise the normal flow of the medium will be cut off.

The HC41X silencing check valve integrates multiple advantages such as energy saving, silencing, and long service life, and its core performance characteristics are as follows:
-
Low fluid resistance, energy-saving and efficient: The valve body cavity adopts a streamlined design, and the flow channel is designed according to 100% full flow. By reducing sharp bends, corners, and sharp protrusions in the flow channel, the resistance of the fluid is greatly reduced, reducing energy loss during medium transmission and achieving energy-saving effects.
-
Excellent silencing effect: The front and rear of the valve disc are designed with a conical structure, which not only further reduces fluid resistance but also effectively reduces noise generated by fluid turbulence. At the same time, the hollow thin-shell structure of the valve disc reduces the inertia of the valve disc, reducing impact noise during closing.
-
Effective water hammer elimination: The valve adopts a short-stroke closing design, and the closing stroke is only 1/4 of the nominal diameter, which significantly shortens the valve closing time and reduces the generation of water hammer. In addition, the spring-loaded design of the valve disc accelerates the closing speed, further enhancing the effect of water hammer elimination and protecting the pipeline system.
-
Flexible installation: It breaks through the installation restrictions of ordinary check valves and can be installed in vertical, horizontal, inclined, and any other angles, adapting to different pipeline layout requirements and improving the flexibility of use.
-
Stable and reliable performance, long service life: The valve disc has a flexible opening and closing performance, and the overall structure has good fatigue resistance, ensuring stable operation for a long time. The internal and external surfaces of the product are sprayed with environmentally friendly coatings, which effectively improve the corrosion resistance of the valve and ensure the safety and service life of the product.
-
Good sealing performance: The optimized design of the valve disc and sealing structure ensures tight sealing when the valve is closed, without leakage, and ensures the stability of the pipeline system.
