Detail Information
JHL41X-type flange multifunctional three-in-one Check Valves is installed on the pump outlet of the general construction, the supply and drainage water for apartments and factories, heating and cooling water treatment, and boiler condensate water, secondary water supply pipes. It is used to prevent the media backflow in pipes that caused by the pump stop running.
1. Using one valve, can successfully complete three kinds of functions: no water hammer check valves, gate valve, balance valve
2. When Pump stops, the spring force closes the disc first, and thus to prevent water hammer.1. Using one valve, can successfully complete three kinds of functions: no water hammer check valves, gate valve, balance valve
3. Through regulating the opening, you can adjust the pump output
4. By using indicator, you can confirm the valve opening degree with eyes.
5. The sealing gasket is made of NBR, and thus will not leak, can absorb the impact force.
6. Spring is made of stainless steel, thus has strong corrosive resistance.
7. It can save water yield equipment materials and cost, reduce installation space.
8. As the shape and advanced structure are streamlined, so the pressure drop is small.
9. As the play the role of bypass, so that it hasthe function of recovering the export inside pipe water, and supplement diversion when the import side appears vacuum.
10. Horizontal pipes, vertical pipes can both be installed.

I graduated with a degree in Mechanical Design and began my career in 2012 as a QC engineer in the workshop. I worked my way up through CAD engineering and eventually served as Chief Technical Engineer. I joined Shinjo Co in 2016 and have since focused on control valves and a wide range of challenging process conditions, supporting numerous overseas clients with demanding applications.
Over the years, I have come to believe that quality and solution capability are what ultimately maximize value — for both the client and the company. We welcome complex and unconventional cases. I hope my industry experience can be of help to you.
