Parameter Value / Description Notes
Thread Size / Cavity C08-2 This is the standardized cavity code per CETOP RP 121 H or ISO 7789. It defines the thread and installation dimensions.
Nominal Size 8
Maximum Operating Pressure 350 bar (5,075 psi)
Cracking Pressure (Free Flow) Typically < 0.4 bar (6 psi) Very low pressure drop in the free-flow direction.
Pilot Ratio ~ 3:1 to 4:1 (e.g., 3.5:1) A common ratio, meaning the pilot pressure required to open the valve against the load pressure is roughly Load Pressure / Pilot Ratio. This is a key specification to verify.
Maximum Flow Approx. 40 - 60 L/min (10 - 16 US gpm) Dependent on permissible pressure drop.
Seal Material Typically Nitrile (Buna-N) Standard for petroleum-based hydraulic fluids.
