Large diaphragm-seat seal working surface, bigger 40% more than general product, guarantees greater precision and sensitivity to maintain its operating characteristics unchanged overtime.
The automatic filling unit is a device consisting of pressure reducing valve, stainless steel filter, shut-off valve and a check valve.
With visual design, installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system stable at a set value, automatically filling up with water as required.
This product has the characteristic of being pre-adjusting, which means that it can be adjusted at the required pressure value before the system charging phase.
After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached.
Built-in shut-off valve and check valve.
