Do you know the types and characteristics of radiator bleed valves?

There are many types of bleed valves on the market, which are different from the appearance, and there are many points from the material; But there are only two types of operation: manual bleed valve and automatic bleed valve

1. Manual bleed valve: At present, most of the radiators on the market are manual bleed valves. The manual bleed valve is controlled by the way of wire blocking, when deflating, use a screwdriver to loosen the screw plug to deflate.

The characteristics of the manual bleed valve are cheap, durable, and easy to repair, but it is prone to water splashing during operation, and it will accidentally splash water on the wall or floor, so be careful when operating.

2. Automatic bleed valve: The automatic bleed valve is composed of an air storage tank and a floating plug. Under normal circumstances, because the air storage tank is water, the buoyancy of the water is greater than the pressure pressure, therefore, the floating plug is closed under the action of buoyancy, so the water cannot get out. When there is air in the radiator, the pressure chamber is at the highest position of the radiator, so the air will enter the air storage tank, separate the water from the buoyancy plug. Without the action of buoyancy, the buoyancy plug opens to realize the effect of automatic deflation.

The characteristics of the automatic bleed valve are mainly convenient and safe; But the price is slightly more expensive, and it is easy to damage if the water quality is not good. This is why most Radiator manufacturers do not like to use it.
