Check valve 12 L (M18x1.5), cracking pressure 2 bar, zinc-plated steel

Once installed, the check valve lets the medium pass in one direction only and shuts off the reverse flow by itself. In addition the sheet lists a working pressure of 250 bar. Decisive for the selection is a cracking pressure of 2 bar.

Benefits

• Cracking pressure 2 bar with a tolerance of about 20 per cent.
• Working pressure up to 250 bar at the 12 L (M18x1.5) tube port.
• Temperature range -20 to +100 °C, the seal is NBR or FKM in the 1.4571 version.
• Material zinc-plated steel, light series.
• The cutting ring port joins the valve to the 12 L (M18x1.5) tube without a weld.

Applications

In a hydraulic circuit the valve with 2 bar cracking pressure protects a pump against reverse flow.
