Solar auxiliary water tank float valve Small size and high pressure resistance → East Star float valve

The solar auxiliary water tank is filled with cold water by a pressurized motor. Due to the small space of the auxiliary water tank and the high water pressure, it is the best choice to use a water inlet float valve with a high pressure resistance and a small volume.

Balanced float valve, small ball short rod can withstand high pressure

Solar auxiliary water tank-the water pressure on the floating ball is large

The structure of the solar auxiliary water tank is similar to the structure of the bathroom water tank. The water source is fed from the water inlet, and the floating ball is used to withstand the water pressure of the pressurized motor. When the water volume is insufficient, the water is filled into the tank. Close the valve to enter the water. The floating ball is connected to the cold water supply of the solar water heater for water replenishment.

Solar water inlet — Solar water tank float valve

It is a traditional and common way to use the auxiliary water tank to supply cold water to the solar water heater. However, since the water supply process cannot be filled in place at one time, it often causes the pressurizing motor to run intermittently, which may easily cause damage to the pressurizing motor. Some manufacturers’ auxiliary water tanks even use plastic buckets that cannot bear the pressure to transfer the pressure to the floating ball valve.

In addition, after the auxiliary water tank is installed, the cold water pressure will become smaller, so there will be different pressures of the cold and hot water, resulting in sudden cold and hot. In order to avoid these problems, some customers will increase the height of the water tower and do not use the auxiliary water tank to reduce the maintenance cost of the booster motor. However, when the general owner asks the manufacturer to assemble the solar water heater, the auxiliary water tank is still the majority. Therefore, in order to withstand the high water pressure of the auxiliary water tank, it is recommended that your float water inlet should use a pressure-resistant float valve.

The solar sub-tank uses a small and high-pressure-resistant float valve.

the function and size of ABS balanced float valve is just right

In view of the fact that the auxiliary water tank configured by the manufacturer is usually not large, sorecommend you to use ABS high pressure float valve。

ABS float valve can withstand high water pressure. It is not easy to be destroyed due to water pressure. However, if your water is not good and the sediment is too much, you can install a set of filters to avoid fouling blocking the valve and causing the float valve failed.

The heat-resistant temperature of the ABS main body and the PE ball is about 70-80 degrees. For the auxiliary water tank that stores cold water, although there is strong sun exposure, the water temperature in the water tank will still be below 50-60 degrees. It is within the temperature resistance range of ABS products, so there is no worry about deterioration.

Stainless steel float is resistant to high temperature

Install this product in the cold water tank, it is really just the right size.

f you are afraid that the water in the water tank is too hot, you can try to usestainless steel float.

Due to the small size of the auxiliary water tank, it is necessary to install union joints as a movable joint during disassembly and assembly. For details, please refer to the video instruction below.

According to the above method, Mr. Taoyuan Fu installed the balanced Float valve in the Suncue Solar Sub-tank.

Suncue solar water tank float valve — use union joints

Since the volume of the Suncue water tank is very small, the balanced float valve cannot rotate in the water tank, so please cut off the piping outside the water tank first, and then put the float into the water tank. After rotating the piping, install the union joint. It is convenient for maintenance and replacement in the future.
