Pressure Compensated Flow Control Valves

Brand: Parker Hannifin
Add Product to My Catalog

Parker’s family of pressure compensated flow control valves feature a proven design that allows for a reliable and repeatable flow compensation curve throughout a wide pressure range. 

These valves can operate with hydraulic system flows as high as 56 lpm and pressures up to 420 bar with the option of an integrated adjustable or tuneable reverse free-flow check valve. 

Parker’s pressure compensated flow control valves are ideal for cylinder or motor control and/or bleed-off applications within a broad range of markets, such as the agriculture, construction, material handling, industrial, and oil & gas markets.
Features
  • Minimal flow change with pressure variation 
  • Reverse flow function 
  • Hardened working parts for maximum durability 
  • Tamperproof options available 
  • All external parts zinc plated
