This Thermostatic Recooling Two-Way Valve Is Designed To Protect Central-Heating Heat Sources Against Overheating.

The Fill And Drain Valves In Its Brass Body Are Controlled By A Thermostatic Element. When The Limit Temperature Is Reached, The Drain Valve Opens, Enabling The Overheated Water Escape From The Heat Source Into The Sewer System.

At The Same Time, The Filling Valve Opens To Let Cold Water In From The Mains. As Soon As The Water Temperature Drops Below The Limit, Both The Valves Close.

If The Pressure In The Mains Could Be Above 6 Bar, It Is Necessary To Install A Pressure Reducer At The Inlet Of Cooling Water. It Should Be Installed As Well If The Pressure In The Heating System Is Too High After Recooling.

In Such Cases The Pressure Of The Reducing Valve Should Be Set Approximately To Double Value Of The Pressure Required In The Heating System, Not Less Than 2 Bar.
