Watts differential pressure valve is designed to provide the necessary safety during use in radiators. This safety valve, of double valve type, is ideal for protecting the heating system from potential excessive pressures. When the system pressure exceeds preset values, the valve automatically opens, allowing depressurization and thus ensuring safety for both people and materials. It is installed at the highest point of the setup and operates without the need for a switch or ball valve, offering easy and efficient operation. Its double valve design allows for effective media flow, making it suitable for any central heating installation.
