In June 2018, Runxin started the research and development of the ultra-high cost-effective Q series control valve. In early August of the same year, the Q series control valve with a water output of 2m³/h and 4m³/h was launched on the market. Q series control valve has accumulated many years of control valve research and development experience of Runxin Company and optimized a number of designs. It adopts a brand-new display method, reduces production costs and after-sales maintenance costs, and is the result of continuous improvement of production technology.

 

Q series control valves have been greatly welcomed by users as soon as they are on the market. The super cost-effective, reliable quality, user-friendly Chinese and English panel intuitive display status and operation methods are widely used in filtration, softening and reverse osmosis pretreatment systems. According to statistics, up to now, the use of Q series control valves on the market has exceeded 150,000 sets.

 

In June of this year, Runxin Company extended the technical characteristics of the 2-4m³/h Q series control valve to the 10m³/h control valve, and the super cost-effective 10m³/h control valve N74Q/N75Q came into being.

 

N74Q/N75Q combines the characteristics and advantages of Q series control valves and N74A/N75A:

 

 

 

1. Improved the structure of the spool moving piece and fixed piece, using an improved motor, which is smaller in size, lower in power, and more environmentally friendly. The motor is installed from top to bottom, and the production efficiency is greatly improved. After-sales maintenance, disassembly, installation, Operations such as replacing parts are more convenient and faster.

 

 

 

2. Improved power adapter, using plug-in power supply, smaller size, lighter weight, can be directly plugged into the plug-in board or wall socket, not only saves space, but also saves costs.

 

 

 

3. Improve the display board, using four digital tubes, 4 indicator lights and four buttons to complete all displays and operations. The 4 indicator lights indicate the flow unit (flow type), instantaneous flow (flow type), The running days (time type) and flushing/regeneration time (time type) are displayed more concisely and clearly.

 

 

 

4. Improve the model adjustment method, you can directly adjust the model by pressing the function key and the return key at the moment of power-on, which is more convenient and faster.

 

In addition, the main control board, positioning board, valve body and dust cover of N74Q/N75Q and N74A/N75A remain unchanged, and the actual installation size and position remain unchanged, which is good for replacement and easy to update and replace. It also integrates multiple functions such as automatic saving of power-off data, signal output, remote control and interlocking.
