Specifications
Supplier part number: FES_40_CA-3X-670LK4M
Name:Proportional Flow Control Valve (Rexroth - BOSCH). - 2-Way Proportional Throttle Valve Type FES. - Nominal Size 40. - Porting Pattern To DIN 24342 Form A. - Without Integral Control Electronics.
Description:The Bosch Rexroth Type FES 40 valve is the correct 2-way proportional throttle valve for your specified configuration without integral control electronics. 🔧 Technical Specifications for NG40 FES Valve The following table summarizes the key technical parameters for the Type FES 40: Parameter Specification Valve Type FES (2-way proportional throttle valve without integral electronics) Nominal Size (NG) 40 Component Series 3X (Series 30-39, dimensions unchanged) Max. Operating Pressure 315 bar (at ports A, B, and X) Porting Pattern DIN ISO 7368 (cartridge type) Nominal Flow Rate 670 L/min (at Δp = 10 bar) Max Flow Rate (A→B) 680 L/min (at Δp = 10 bar) Max Flow Rate (B→A) 585 L/min (at Δp = 10 bar) Area Ratio (Main Spool) 2 : 1 Weight 8.2 kg (FES) / 8.4 kg (FESE) 💡 Understanding the Valve Type The Type FES is designed for use with an external control electronics unit, which must be ordered separately. This is distinct from the "FESE" variant, which has on-board electronics (OBE). Key features of the FES valve include: Pilot-operated, 2-way proportional throttle valve for block installation Command value-dependent position control of the orifice spool The position of the main spool is controlled in a closed loop using an external amplifier and an inductive position transducer 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 🔧 Ordering Code Example Based on the ordering code structure from the official Rexroth documentation, a complete ordering code for this configuration could be structured as: FES 40 CA-3X/670LK4M. The code elements represent the valve type, size, spool variant, component series, flow rating, and options.
