Pressure Switch JH-1.2
Description:
The Electronic Controller orders the automatic start and stop of the water pump when opening or closing any tap or valve of the system. The controller can keep constant pressure and water flow in the system as long as any tap in the system is open during the pumps operation.
It allows the pump to run at a constant flow. The controller stops rapid cycling of your pump unit, eliminating water fluctuating through your home.
Automatic Pressure Control Switch connects to the discharge of the water pump and operates with an electronic circuit board to sense the pressure and flow in the system. Fit most common water pumps.
Construction characteristics:
-Inlet: R1’’
-Outlet: R1’’
-Special non return valve to avoid surges
-Pressure gauge
-Manual start switch (Restart)
-Tension LED: (Power)
-Pump-working LED: (On)
-Security system LED: (Failure)
-Security system avoiding the possibility for the machine to work without water
Function:
1. Automatic pressure switch used for drinking water or non-potable water piping systems.
2. Replace the traditional system which assembled with pressure switch, pressure tank and
check valves.
3. Stop the pump automatically when water shortage.
4. It starts the pump automatically when pressure decrease (tap opening) and stops it when
there is no flow (tap closing).
