HD7Q41X full hydraulic control check valve
Product number:HD7Q41X
product description:

  This butterfly valve is suitable for the pump outlet pipeline where the medium is water. It is used as a closed circuit and check valve to avoid and reduce the backflow of the medium in the pipeline system and excessive water hammer to protect the pipeline system.

Product Usage:


  This butterfly valve is suitable for the pump outlet pipeline where the medium is water. It is used to avoid and reduce the prosperous backflow of the medium in the pipeline system and excessive water hammer to protect the pipeline system. Its function is to replace two valves with one valve (traditional In the pipeline design, gate valve with check valve or ordinary butterfly valve with check valve)

Features:

1. The control part of HD7Q41X full hydraulic control check butterfly valve adopts full hydraulic control, and the heavy hammer part is taken with the accumulator, which reduces energy loss, the transmission mechanism is simplified, and it takes up more space. similar.The installation is convenient, that is, horizontal installation on the left and right sides of the lesson, or vertical installation.
2. The valve is installed behind the pump and can replace the gate valve (butterfly valve) and check valve.And the flow resistance coefficient is small, and the flow resistance coefficient of the large-diameter butterfly valve is only slightly higher than that of the gate valve.Therefore, this type of valve is an energy-saving product.
3. When the HD7Q41X valve is closed, the fast and slow closing time and switching angle can be adjusted according to the characteristics of the pipeline system or user requirements, so as to eliminate or reduce water hammer and protect the system.
4. If all travel switches adopt inductive proximity switches, remove the hydraulic station, and the protection level can reach IP67.
