Operating Pressure : 350BAR
Flow : 380L/min
Internal Leakage : 0.7ml/min.max.to 90% of norminal setting
Temperature : -30°C to +120°C(-22°F to+250°F)
Cavity : T-16A see page K-3
Fluids : Mineral-based fluids with viscosities of 7.4 to 420 cSt.
Will accept maximum pressure at port 2; suitable for use in cross port relief circuits.
The seals on the adjust screw are exposed to system pressure which means this valve can only be adjusted when the pressure is removed.
The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting.
Valve is relatively insensitive to varying oil temperatures and oil contamination.
Direct-acting relief cartridges are normally closed, pressure-limiting Valve used to protect hydraulic components from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These Valves are smooth and quiet, essentially zero leak, dirt tolerant, immune to silting and are very fast.
