Specifications
Check valves with free flow in one way and blocked in the other way for preventing reverse flow and stopping back pressure in hydraulic and pneumatic circuits. In the valve, there is an automatic lock system with a piston and a spring. Pressure up to 400 bar. The standard minimum differential pressure is 0.5 bar.

  1. Used in high pressure circuits for hydraulic services, corrosive services, high temperatures, etc.
  2. Used in circuits where a compact design is required and entirely metallic
  3. These valves consist of a closing loose piston that, optionally can return by spring
  4. Two versions:
    - Medium type (until 255 bar)
    - Heavy type (until 425 bar)
  5. Opening from a differential pressure of 0’5 bar
