Refill system with solenoid valve

Automatic refill system with (stainless steel) water sensor and time-controlled 15 mm solenoid valve. For refilling a pond, pool or water tank with tap water. Suitable for open water and pools made of metal, plastic or concrete. You place the control box of the filling system indoors, in the garden house or garage, near the solenoid valve that is mounted in a 15 mm supply pipe. The refill system works with 1 sensor that signals as soon as it runs dry.

Top-up with tap water

Based on the height of the sensor pins, you set the switching point. The solenoid valve opens as soon as the sensor goes dry and closes automatically when the water level is back up to standard. This control cycle repeats itself without you having to set or reset anything. You need to determine once how long the valve should be open. Then the refill system functions independently, i.e. even in prolonged absences.

Solenoid valve with control cable

The industrial solenoid valve has 15 mm compression fittings, for quick assembly without soldering. This water valve is fitted with a waterproof connection. The plug of the matching control cable (not shown) plugs into the socket on the control box.

Plastic sensor or stainless steel version

This filling system is Plug & Play (see illustrations) and comes complete with the level sensor with 10 m signal cable: optionally in plastic or stainless steel (see illustrations). If required, this can be extended with an RJ45 data cable.

Setting the duration

On the control box, you can accurately set how long the valve should be opened per cycle. There is a button for 0 to 60 seconds and one for 1 to 10 minutes.
Calculated from the switch point, the refill time is a constant, determined by the content of the basin and the number of litres of water.

Adjustable 230 Volt output

With a switch on the front panel, the 230 Volt output (the socket) can also be set to off.
