Description

2FRM10-3X/50LB, manufacturer material number R900423261, is a Bosch Rexroth size 10 mechanically adjusted, pressure-compensated two-way flow control valve. It regulates flow from A to B and provides free reverse flow from B to A through the documented check valve. Its B option limits pressure-compensator stroke to reduce the start-up flow surge.

The manufacturer specifies a maximum inlet pressure of 315 bar at A. The coded flow range is adjustable and does not specify a factory-set flow. Required minimum pressure differential depends on nominal size and selected flow. Free reverse flow is through the integrated check valve; bidirectional regulated flow needs a separately selected rectifier plate.

Representative manufacturer family photograph; the delivered size and execution may differ.
