Technical Principles and Innovative Values​

Innovation Point 1:Servo-Grade Proportional Control​

Conventional hydraulic valves use on/off solenoids,leading to jerky motion and poor repeatability.The 4WRSE10V80-32 G24K0 A1V-695 R900247749 integrates a proportional solenoid with magnetic feedback,achieving±1%linearity between electrical input(0-10V)and flow output.A U.S.aerospace component manufacturer used this valve to control a hydraulic press for titanium forming:part dimensional accuracy improved from±0.15mm to±0.02mm,reducing rework costs by 85%compared to old on/off valves.​

Innovation Point 2:Anti-Pollution Spool Design​

Hydraulic system failures are often caused by fluid contamination(70%of issues,per Rexroth data).This valve’s spool features a patented groove design that traps small particles(up to 25μm)and prevents them from jamming the spool.A construction equipment maker tested this in dusty mining environments:valve lifespan increased from 6 months(old models)to 3 years(4WRSE10V80-32),cutting maintenance costs by$12,000 per machine annually.​

Innovation Point 3:High-Pressure&Fast Response​

Heavy-industry applications(e.g.,5,000-ton presses)require both high pressure and rapid response.The valve’s 350bar continuous pressure rating handles extreme loads,while its≤10ms response time ensures precise synchronization with other system components.A Chinese steel mill used the valve to control a rolling mill’s hydraulic gap adjustment:the fast response reduced roll bounce by 60%,improving steel plate flatness from±0.5mm/m to±0.1mm/m—meeting automotive-grade material standards.​

5.Application Cases and Industry Value​

Case 1:CNC Machine Tool–Hydraulic Chuck Control​

A Japanese CNC machining center manufacturer struggled with inconsistent workpiece clamping using outdated valves.The old valves caused±0.08mm runout in precision turning,leading to 3%part rejection and€12,000 in monthly losses.​

After upgrading to REXROTH 4WRSE10V80-32 G24K0 A1V-695 R900247749 valves:​

Proportional pressure control reduced chuck runout to±0.01mm,cutting rejection to 0.3%​

Fast response(≤10ms)synchronized chuck clamping with spindle start,reducing cycle time by 5%​

Anti-pollution design extended valve life to 2 years(vs.8 months for old valves),saving€9,600 in replacements​

The engineering manager stated:“This valve’s precision has elevated our machining centers to compete in the high-end medical component market.”​

Case 2:Construction Machinery–Excavator Arm Control​

A Korean construction equipment maker faced operator complaints about jerky excavator arm movement,caused by slow-response valves.This led to reduced digging efficiency and increased operator fatigue.​

Installing the 4WRSE10V80-32 G24K0 A1V-695 R900247749 resolved these issues:​

Linear proportional control smoothed arm movement,reducing operator fatigue by 40%(per user surveys)​

350bar pressure rating handled heavy loads(e.g.,10-ton concrete buckets)without performance loss​

Anti-pollution design tolerated dusty job site conditions,cutting valve-related downtime by 80%​

The product director commented:“This valve has become a key differentiator for our excavators—operators now prefer our machines for their smooth,precise control.”​

7.Installation,Maintenance,and Full-Cycle Support​

Installation&Commissioning​

Installing the REXROTH 4WRSE10V80-32 G24K0 A1V-695 R900247749 requires adherence to hydraulic best practices.First,verify the valve model and part number(R900247749)to ensure compatibility with your system.Flush the hydraulic circuit to ISO 4406 Class 18/16/13 cleanliness—contamination is the top cause of early valve failure.Mount the valve to an ISO 4413(CETOP 3)manifold using torque wrench(25-30 N·m for bolts)to avoid leaks.​

Connect the 24V DC solenoid power supply(use shielded cable to reduce EMI)and proportional amplifier(e.g.,VT-VSPA1).Prime the hydraulic circuit to remove air,then power on the system.Use the amplifier to calibrate the valve:send 0%,50%,and 100%input signals,verifying flow rate matches specifications(use a flow meter).Adjust the amplifier’s gain if linearity deviates from±1%.​

Maintenance&Fault Handling​

Routine maintenance for the 4WRSE10V80-32 G24K0 A1V-695 R900247749 focuses on fluid condition and mechanical integrity.Conduct monthly checks:measure hydraulic fluid cleanliness(use a particle counter)and replace filters if contamination exceeds Class 18/16/13.Inspect valve connections for leaks—tighten bolts if needed(do not exceed 30 N·m).​

If performance degrades(e.g.,slow response,erratic flow):​

Check fluid temperature(should be<80℃)–overheating degrades oil viscosity and seal life.​

Verify solenoid voltage(24V DC±10%)–low voltage reduces response time.​

Inspect the proportional amplifier–faulty amplifiers cause non-linear flow output.​

For severe issues(e.g.,valve stuck),use Rexroth’s diagnostic software(via CANopen)to read fault codes—common issues include spool jamming(resolve with fluid flushing)or solenoid failure(replace with Rexroth genuine solenoids).​
