After the installation of the rear wall connection with an integrated shut off valve the main component the pressure regulator is screwed on Only a metallic sealing is utilised without additional sealing elements The pressure regulator has different outlet and connection variations downstream As an option a control shut off valve can be installed in the outlet of the pressure regulator There is also the option of screwing a control shut off valve or a wall outlet without pressure regulator directly onto the rear wall connection The rear wall connection contains a non return valve that makes it possible to uninstall a tapping point from a rear wall connection at any time without having to vent the pipe arranged upstream beforehand This also makes it possible to include points in the structure at which a tapping point can be connected later The entire gas supply system can continue to operate uninterrupted while the tapping point is connected at a later time The outlet pressure can be adapted to new requirements by replacing the tapping point The pressure regulator s shut off valve is actuated using what is called the rotary lever Depending on the position a colour mark on the pressure regulator is either red to indicate the closed position or green to indicate the open position of the shut off valve Open position Closed position The pressure regulator s pressure setting is controlled using the hand wheel which
