② Solenoid Valve on Inlet( Set b-02)
Instruction: When inlet pressure exceeds 0.6MPa, install a solenoid valve
on inlet. Control mode is b-02. Pressure relieved when valve switching, the
wiring refer to Figure 3-2. As Figure 3-3 shows, it also can use the pressure
relief port to work.
Function:
When inlet pressure is high, install a solenoid valve on inlet to ensure
valve switching properly. When valve is exactly at position of Service,
Backwash, Brine& Slow Rinse, Brine Refill and Fast Rinse, solenoid valve
is open. When valve is switching, solenoid valve is closed, no water flow
into valve to ensure valve switching properly. It could prevent the problem
from mix water and water hammer.
Use interlock cable to realize valves in parallel and series in same
system which is suited for RO pretreatment system or second grade Na
+
system. The wiring refers to Figure 3-4:
