PARKER HANNIFIN FR101F200 - Pressure Compensated Flow Control Valves

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.

Markets:
• Agriculture
• Construction Equipment
• Material Handling Equipment
• Miscellaneous Industrial
• Miscellaneous Mobile
• Oil & Gas

Features/Benefits:
• Minimal flow change with pressure variation
• Reverse flow function
• Hardened working parts for maximum durability
• Tamperproof options available
• All external parts zinc plated

Applications:
• Accumulator bleed-off
• Motor speed control
• Cylinder speed control
• Power units

Additional Technical Insight:
Parker offers a wide range of spool type restrictive pressure compensated flow controls to allow for speed control of motors, cylinders, and rotary actuators. Pressure compensation allows the flow devices to maintain a constant flow even with varying loads and inlet pressures. Tunable and fully adjustable versions are available with screw or knob adjusters that can be made tamper resistant with the addition of an optional cap. FR101 is an adjustable pressure compensated flow regulator which compensates for varying loads and pressures in one direction but in the other direction flow is metered across a fixed orifice but not compensated. In order to allow pressure compensated flow control in one direction and full free flow in the opposite direction, Parker offers an internal check valve in the adjustable FC101 cartridge. Because both versions are tunable and not fully adjustable, the valve will need to be specified with the appropriate flow range for the application. Changes in flow rates are achieved by mechanically varying the spring force acting on a spool that has a fixed orifice and metering compensator. J02E2, J04C2, and J04E2 are fully adjustable pressure compensated flow regulators. In the opposite flow direction, those valves only meter through a fixed orifice and do not compensate. In order to achieve fully adjustable pressure compensated flow control while allowing reverse full flow, the FA101 includes an internal check valve to bypass the compensator and metering orifice.
