What Is a Backwater Valve?

The return water cut-off valve is installed at the return end of the radiator to adjust the pressure difference between the inlet water and the return water to ensure the low noise operation of the radiator and achieve the hydraulic balance at the end, and adjust the resistance balance of each heating loop. The product has a flow mark that is not available from other manufacturers.

In some facilities that use hot water, it is necessary to open or close the valve after the water reaches a certain temperature. For example, in a solar hot water system, the temperature of the water in the solar collector must reach 60 ° C before the valve is opened. Water is stored in the water tank, and the valve is closed if it is below 60 ° C. Such a control method is generally implemented by an electronic control method at present, which requires a high cost and inconvenient installation such as a power supply, a temperature control instrument, and a solenoid valve.

Our company has developed a passive intelligent temperature switching valve, which can solve the above problems with only one valve. It does not require a power supply, which is safe, reliable and energy-saving. This valve can set the opening and closing temperature values. The water temperature automatically reaches the set value. Close or open the valve.

This valve uses safety, mechanical control, no power supply and long life. The user can set the start and end temperature of the valve.

For hot water heating systems and cold water distribution systems. Pre-adjustment and closing of the valve body. Brass nickel-plated valve core with EPDM O seal ring protection cover. With additional soft seal. Suitable for threaded pipes, low temperature welding The structure of the clamped pipe joint conforms to the German industrial standard DIN3842.
