Operating Pressure 270BAR
Internal Leakage 0.3ml/min.max.to 85% of norminal setting
Pilot Ratio 4:1
Temperature -30°C to +120°C(-22°F to+250°F)
Cavity T-3304S see page K-20
Fluids Mineral-based fluids with viscosities of 7.4 to 420 cSt.
Counterbalance Valve should be set at least 1.3 times the maximum
Port ② can not be set full pressure, otherwise it will affect the set
The valve controls moving load and preventing it from running ahead of the
pump,locking the load in any position,it also provides static overload
and the mal enpansion protection.The valve allows free flow from ② to ①
and blocks reverse flow unit a pilot pressure proportional to the load pressure
is sensed at ③ modulating flow from ① to ② .
