Check valve, Hose (inlet) - thread (outlet), M5, hose 4 - Riegler 106812

Check valve »lineonline«, Hose (inlet) - thread (outlet), M5, for hose Ø 4 mm, Operating pressure 0.5 to 12 bar These valves ensure that compressed air only flows in one (i.e. the desired) direction. The valve closes when inlet pressure is lost and maintains the working pressure that is present downstream.

About Mini pressure regulators and function connectors

Miniature pressure regulators and function fittings are installed straight into the air line and handle regulating, switching and throttling duties there, without needing a mounting plate of their own. The control range covers 0 to 8 bar and flow rates run from 50 to 850 Nl/min.

What matters when choosing

• The thread decides where the part sits. M5, G 1/8, G 1/4 and G 3/8 male threads are available.
• For the regulators the deciding figures are the 0 to 8 bar control range and the 10 bar maximum inlet pressure. The secondary pressure should be set in the middle of the scale rather than at its limit.
• Flow rates cover 50 to 850 Nl/min. Short cylinder cycles or longer pipe runs should be planned around the upper half of that range.
• Maximum operating pressure is between 7 and 12 bar depending on the version. Networks running permanently close to 8 bar rule out the types limited to 7 bar.
• Electrically actuated versions run on 24 V DC. Versions with an indicator cover a measuring range up to 12 bar.

Typical applications

• Reducing pressure at individual cylinders when only one branch has to run at a lower level
• Setting actuator speed directly at the cylinder or valve port
• Retrofitting existing lines where there is no room for a full air preparation unit
• Handling and gripping equipment where clamping force is limited through pressure
• Test and assembly fixtures with 24 V control
