Energy Saving Silencing Check Valve
Product overview
HC41X Energy-saving silencing check valve is suitable for water supply and drainage pipes. The valve disc is guided by the central axis at both ends of the inlet and outlet. It can be opened and closed flexibly. It can be installed horizontally or vertically. The valve disc is loaded by spring. Its fast closing can effectively eliminate water hammer, with good sealing performance and no noise during closing. The utility model has the advantages of small volume, light weight, small fluid resistance, fatigue resistance, long service life, etc.
Product Features
1. The valve disc adopts the "bullet head" shape design, and the valve body adopts the "waist drum" shape design to improve the medium flow direction and reduce the flow resistance coefficient
2. The valve is of short structure. Although the head loss is slightly larger than the lift silent check valve, it is small in size and cheap in price
3. The structure is compact, non-metallic lubricating sleeve is installed between the guide shaft and the guide frame, so the valve disc can be lifted and lowered flexibly without locking
4. The framework type rubber seal ring is directly inlaid on the valve body to avoid the direct erosion of the medium on the sealing ring for a long time, and the service life is obviously prolonged, which is firm and durable
5. The opening and closing stroke of valve disc is short, which can effectively prevent water hammer
6. It is suitable for water supply and drainage system and high-rise building pipe network. It can be installed at the outlet of the pump with slight structural changes. It can be used as suction bottom valve, but not suitable for sewage pipe network
