“One Dynamic and Two Static” Double Static Ceramics Plates Multi-port Valve is on behalf of another beginning in the field of water treatment control, which can overcome many disadvantages of traditional products in installation.


Flexible 7 or 12 day time clock or meter initiated regeneration
Fully adjustable, 5-cycle control delivers upflow back wash, downflow brining, slow rinse, rapid rinse and down flow service
Designed for single tank or multi-tank systems, alternating or interlocking
Continuous flow rate of 250 GPM


Meter and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.
