400 Bar GFG2 Parker 2-Way Flow Control Valve Series, For Water

Parker's 2-way flow control valves series GFG ensure a constant flow rate independent of pressure and temperature fluctuations. The GFG is optionally equipped with a built-in check valve for the return flow.Markets:IndustrialMachine toolsFeatures/Benefits:Pressure compensated flow-movements are precisely executedWide range of different flow rates-enables fine adjustmentShort delivery time - no warehousing necessaryExternal port (P) to block flow from A to BOptional reverse flow check valveTurn knob with cylinder lock (option S)Applications:Suitable for general hydraulic applicationsMachine toolDesign:The 2-way flow control valves are used with a triangular flow restrictor and a subsequent pressure compensator. The setting of the flow rate can be locked by a cylinder lock in the adjusting knob against unauthorized adjustment (option S).Function:The fluid enters through port A through the flow restrictor. Downstream of the flow restrictor the pressure compensator is located. The control edges are provided by four radial bores in the poppet, which are fully open to port B in the neutral position. Optionally the flow from A to B can be blocked by external pilot pressure applied to port P (option X). This can be used to avoid unintended initial movements of actuators. The flow adjustment is done via the hand knob with an adjusting angle knob of 270 Degree.
