GVO 150501020027A Balance Valve RDDALAN Pressure Relief Valve Control Valve for Excavators

 Key attributes

Precision Overload Protection
Fast Response to Pressure Shocks:

  As a normally closed pressure-limiting valve, it protects hydraulic components from transient pressure spikes. When the inlet (port 1) pressure reaches the preset value, the valve opens rapidly to relieve oil to the tank (port 2), limiting pressure rise within milliseconds (typical response time: 2 ms) .

Stable Pressure Control:

  The valve offers smooth, quiet operation and is insensitive to oil temperature changes and contamination, ensuring consistent pressure protection across a wide range of operating conditions.
