Specifications
Supplier part number: FES_63_CA-3X-1800LK
Name:Proportional Flow Control Valve (Rexroth - BOSCH). - 2-Way Proportional Throttle Valve Type FES. - Nominal Size 63. - Porting Pattern To DIN 24342 Form A. - Without Integral Control Electronics.
Description:The Bosch Rexroth valve that matches your exact specification is the Type FES (without integral electronics). For a Type FES valve, external control electronics must be ordered separately . This is distinct from the "FESE" variant, which has on-board electronics (OBE) . 🔧 Key Specifications for NG63 FES Valve The following technical parameters are confirmed for the Nominal Size 63 model from official Rexroth documentation : Parameter Specification for NG63 Valve Type FES (2-way proportional throttle valve without integral electronics) Nominal Size (NG) 63 Component Series 3X (Series 30-39, dimensions unchanged) Maximum Operating Pressure 315 bar Porting Pattern DIN ISO 7368 (cartridge type, also known as DIN 24342 Form A) Nominal Flow Rate 1800 L/min (at Δp = 10 bar) Area Ratio (Main Spool) 1.6 : 1 Flow Direction Bidirectional (A→B and B→A) 💡 Understanding the Valve Type The Type FES is a pilot-operated 2-way proportional throttle valve designed for block installation, providing continuous flow control . The main spool position is controlled in a closed loop using an external amplifier and an inductive position transducer that provides actual position feedback . Key functional features include: Command value-dependent position control of the orifice spool In the event of a power failure, cable break, or withdrawal of the enable signal, the spool automatically moves to the seated position, blocking flow in both directions Can be used in conjunction with a pressure compensator for pressure-compensated flow control 🔧 Ordering Code Example Based on the ordering code structure from the official documentation, a complete ordering code for this configuration is structured as FES 63 CA-3X/1800LK4M (material no. R900979361) . The code elements represent the valve type, size, spool variant, component series, flow rating, and options.
