Oleoweb VRSE check valves are used to hold a single acting cylinder in position, they need a pilot pressure to release the load. The external body is made of high resistance steel and externally protected from oxidations by zinc treatment. The sealing is granted by a tapered poppet hardened and grinded.

Maximum Pressure = 320 BAR (4640 PSI)

Notes:

• Pilot Ratio refers to the pressure require to open the valve when under load. (e.g. Load Pressure = 3000 PSI, Valve Pilot Ratio = 4:1, The valve will require 750PSI to open)
• Low pilot ratios (3:1 and 4.5:1) are for applications where loads may vary widely. Low pilot ratios require higher pilot pressures and are less efficient but provide stable, precise control for varying loads.
• High pilot ratios (8:1 and 10:1) are for applications where loads are relatively constant. High pilot ratio valves require lower pilot pressures, are more responsive, and are more efficient, though they lack stability and precision in response to constantly changing loads
