Acessórios Differential Valve

The differential pressure valve is very useful in systems in which several heat issuer can be closed at the same time due to the closing of zone valves or the environment controller. The differential pressure valve ensure a recirculation proportional wo the number of closing valves, thus avoiding noises and keeping the pump peration constant. It is easily installed in the hydraulic group. It can be installed at any moment.
It is used in circuits that might work with flow variations. Ot limits the maximum pressure produced by the circulation pumps. It stops the circultion pump from working outside its working limits.
