Thermostatic three-way valve body

The thermostatic three-way-valve bodies are used in two-pipe pump heating systems. For one-pipe pump heating systems a retrofitting thermostatic insert is available. When almost all valves are closed at the same time, additional pressures build up in the heating system. If the three-way valve intercepts the radiator flow, the bypass for the return flow is fully opened. Additional pressures are avoided and the pressure is kept almost constant. The bypass can be connected with the corresponding bypass T-piece on the radiator return.
