Air valves DAVAN FLOWTEK DN25, DN50, single, double, etc.

Air valves DAVAN FLOWTEK are designed to neutralize the pressure in the pipes, as well as neutralize odors, for which purpose the system is blocked in case of an increase in pressure. Aerators are made of high-strength plastic or cast iron, as well as stainless steel. Of the main components, the valve itself can be distinguished, which has a special opening and closing mechanism, as well as special rubber gaskets that make it as tight as possible. This is a membrane or rod, the principle of operation of which is one-sided.

In the normal position, the valve is closed. If the pressure increases, the valve automatically opens and lets in air to even out the situation. Aerators are advantageous for their reliability and easy use, comfortable disassembly. On the machine, the aerator is able to cope with a small volume of air, the kinetic one prevents excessive accumulation of air, but the combined version has the capabilities of both.

Models: three-function with two holes, with connected shut-off valves, single with brass ball valve DN25, single with side flange, single with shut-off valve DN50, single with integrated flange.
