Flap valves are an essential element in the field of engineering and automation, playing a key role in controlling the flow of fluids, gases or dust in various types of systems. They are characterized by a unique design based on a flap that rotates around an axis placed in the valve body. Where are flap valves best suited?

How to properly install a flap valve?
Flap check valves are very easy to install. They can be installed both vertically and horizontally. They must be installed in the flow direction, remembering to leave the appropriate clearance when sealing. These types of check valves are extremely mechanically resistant, but remember to equip the installation with a mesh to stop dirt for greater safety.
The flap check valve opens only after reaching the opening pressure, and closes when the threshold pressure drops, i.e. when the flow stops. The valve design provides easy access for any maintenance. The closing element is a flap that swings out of the seat, and thanks to this prevents the medium from flowing back. Note also that the flap valve is resistant to the flow pressure.
What types of flap valves are there?
Flap valves are available in both flanged and inter-flange versions. They have a characteristic closing element, which is a flap. It rotates around its own axis. They can be safely used in installations with large diameters. Of course, it must also be remembered that flap valves operate in the open/close function, but they can also have an angle adjustment option. The flap valve is most often located in a perpendicular position to the pipeline axis, but to fully open it must rotate 90 degrees.
The sealing of the lever ensures effective operation and prevents the medium from flowing back. The use of a flap valve generates low costs, especially since they operate in a wide range of pressures and temperatures. We can distinguish three types of flap valve mountings, i.e. those with a flanged design, with an inter-flange design (the valve is located between two pipeline flanges). You can also choose a valve with an inter-flange LUG design - the valve has threaded holes on both sides of the body.

It is worth choosing flap valves in the Onninen wholesaler. The Gazex MAG-3/DN32 flap valve is worth attention. It is additionally equipped with a counter-flange set. It is a shut-off valve that ensures the safety of the entire installation. It is equipped with two types of electromagnetic triggers. It is characterized by very low flow resistance and, in addition, low weight.
The Gazex MAG-3/DN40 flap valve , which is also sold with a counter-flange set, may also be a suitable choice. It is characterized by high mechanical resistance, as well as work efficiency even in difficult conditions. The nominal pressure in this case is 0.5 MPa.
Another product that can prove useful is the Gazex MAG-3/DN100 flap valve . It serves as a safety system in both private and public installations. It is also worth noting that this model is not sensitive to changes in the voltage supplying the system. Another advantage is that it does not require power supply in both the open and closed positions.
