FCG-H02/H03 Series Flow Control Valves - Pressure Compensated
Eaton’s Vickers ® FCG flow control valves are used to maintain a flow constant largely independent of pressure and temperature.
The valves basically consist of the housing, orifice bushing, pressure compensator with optional stroke limiter,check valve, adjustment element. The flow from channel A to channel B is throttle at the orifice. In order to maintain the flow across the orifice constant, a pressure compensator is connected upstream of the orifice. The flow is maintained largely independent of temperature due to the orifice design. Free return flow from channel B to channel A is directed via the check valve. The flow is only controlled from A to B. In order to control the flows in both directions a rectifier sandwich plate type DGMB can be installed below the flow control valve.
Porting pattern to DIN 24 340, form G,ISO 6263, CETOP-RP 121H and NFPA 3.5.1 MR1
