Runxin control valve is the first domestic multifunctional control valve for automatic water treatment system with completely independent intellectual property rights. Relying on the principle of end seal, multiple valves are tightly integrated into one valve body in a planar circumferential arrangement. When rotating the moving piece, it can realize the function of closing several valves and opening several other valves at the same time.
Main product series：
1.Manual filter valve series：
Manual filter valve 51 series (formerly F56 series) manually control the spool by the handle to achieve the functions of operation, backwashing, forward washing, etc.
2. Manual softening valve series：
Manual softening valve 61, 71 series (former F64 series, F77 and F78 manual series) through the handle manual control valve spool, to achieve the operation, backwashing, suction salt slow washing, salt tank replenishment, positive washing and other functions.
3. Automatic filter valve series：
Automatic filter valve 52, 53 series (former F67, F71, F75, F77B, F78B and other series) have LED, LCD two kinds of display control mode, using the program driven motor control valve spool, according to the time signal to automatically realize the operation, backwashing, positive washing and other functions of the switch.
4. Automatic softening valve series：
Automatic softening valve 62, 72, 82 and 63, 73, 83 series (former F63, F65, F68, F69, F74, F77A, F78, F79, F82 series) have LED, LCD two display control mode, using the program to drive the motor control valve spool, according to the time signal or flow signal or water quality, etc. automatically start regeneration, using the time signal automatically To achieve backwashing, salt absorption slow washing, salt tank replenishment, positive washing and other functions of the switch.
5. Special water control valve series：
Special water treatment control valves 11 (fluoride removal), 13 (oxygen removal), 15 (salt removal) and other series of control valves, using the program to drive the motor control valve spool opening and closing, according to the time signal, flow signal or water quality, etc. automatically start regeneration, the use of time signals to automatically achieve the rest of the functions of the switch.
6. Bypass valve series：
Bypass valve 41 series (formerly F70 series) manually controls the spool by the handle to realize the functions of operation, partial bypass, bypass, etc. The bypass can supply water to the back stage when changing filter media or maintenance time; the partial bypass function of the softening valve can add some raw water to the soft water.
The principle of Runxin valve：
1.Working principle：
Relying on the principle of end sealing, multiple valves are closely integrated in a valve body, which is arranged in a flat circle. When rotating the moving piece, you can achieve the function of closing a number of valves and opening another number of valves at the same time.
Structure principle：
The use of a certain area of high flatness of the two planes of the lamination, can play a role in sealing and blocking the flow. The R&S valve fixes a high flatness fixed sealing piece in the valve body radially, and drives the high hardness and high flatness ceramic dynamic sealing piece to rotate with the fixed sealing piece through the handle or motor, because the dynamic and fixed sealing pieces have different blind holes and through holes, when the dynamic piece stays in different positions of the fixed piece, it can produce different fluid channels, so as to realize the functions of water production, backwashing, salt absorption + slow washing, water replenishment to the salt tank, positive Flushing and other functions. (Note: filter valve to achieve water production, backwashing, positive flushing three functions).
Automatic control valve principle：
Signal → program control valve → transmission device → dynamic valve piece → set device → program controller
The system adopts microcomputer control, with time, flow or water quality as a signal to start the program, through the transmission device to drive the dynamic valve blade rotation, to the corresponding position, through the set device to send the signal to the microcomputer, stop working; when the next signal to meet the set requirements, start again to turn to the next position. In this cycle, during the process of rotating the dynamic valve piece for one week, the required functions are realized.
2.Structure features
End face sealing structure：
A.Ceramic is used for the moving piece
B. The fixed piece is made of high strength synthetic material
C. For various softening valves, partial balance structure is adopted to prevent the increase of sealing surface torque due to the rise of water pressure.
Can be operated with pressure：
The Rinsin valve can be operated directly under pressure when switching between various functions because it adopts two high flatness sealing pieces to rotate and seal each other.
No raw water bypass：
The control valve automatically blocks the outlet pipe of the water softener or filter during regeneration or cleaning to prevent untreated raw water from entering the system.
Simple assembly：
The valve is mainly composed of valve body, dynamic and fixed sealing piece, fork, compression screw plug, etc.; complex parts - valve body is formed in one time, with less processing links and high dimensional stability.
The positioning of each working position is fixed directly on the valve body, with higher positioning accuracy.
When installing, each part is limited in position and will not be installed wrongly.
A variety of specifications of jet streamers are available：
The ratio of salt absorption to total outlet flow of the jetter is between 25% and 35%.
There is one type of jetter to match each tank type.
3 Performance
Runxin valve is more resistant to impurities and has a large backwash flow rate. There are two types of display, LED and LCD, and regeneration methods, such as downstream regeneration and counterflow regeneration, are available. The factory products of R&S valves are 100% tested with 0.1MPa, 0.6MPa air pressure and water pressure and certified by NSF, with strict reliability.
