Product details
Electrical control valve K3V180
Electrical control valve K3V112
I. Model Interpretation (K5V160)
1. K5V:
• K: Typically denotes a hydraulic valve (Hydraulic Valve) or proportional control valve (Proportional Valve).
• 5: Series code, possibly indicating valve structure (e.g., 5-port size or 5-level control precision).
• V: Proportional control (Variable/Proportional), enabling continuous pressure/flow adjustment via electrical signals.
2. 160:
• Usually refers to the valve'srated flow(unit: L/min) ornominal port diameter(unit: mm).
• Example:
• K5V160: Rated flow of 160 L/min, suitable for medium-to-large hydraulic systems (e.g., construction machinery, injection molding machines).
• If indicating port diameter, it refers to a 160mm valve opening (verify with specific product manuals).
II. Key Performance Parameters
【表格】

Filtration Requirement NAS 1638 Class 7 Equivalent to ISO 4406 16/14; replace filters regularly
III. Typical Applications
1. Construction Machinery:
• Pressure control in excavator/loader hydraulic systems (e.g., boom, bucket movements).
• Vibration pressure regulation in road rollers.
2. Industrial Automation:
• Clamping pressure control in injection molding machines.
• Locking force adjustment in die-casting machines.
3. Metallurgical Equipment:
• Tension control in rolling mill hydraulic systems.
• Crystallizer vibration pressure regulation in continuous casting machines.
4. Marine & Offshore Engineering:
• Constant tension control for deck machinery (e.g., winches, anchors).
• Steering gear system pressure stabilization.
IV. Selection Guide
1. Flow Matching:
• Select valve model based on system maximum flow demand (e.g., choose K5V160 for systems ≤160 L/min).
• Formula:Q=V×n1000 Q = \frac{V \times n}{1000} Q=1000V×n
(Q Q Q: Flow rate, L/min;V V V: Pump displacement, cm³/rev;n n n: Rotational speed, rpm)
2. Pressure Verification:
• Ensure system maximum operating pressure ≤ valve rated pressure (350 bar), with transient peaks ≤420 bar.
3. Control Signal Compatibility:
• Confirm controller output signal type (4-20mA or 0-10V) matches the valve.
• Requires a proportional amplifier (e.g., E-PM-01) to drive the spool.
4. Environmental Adaptability:
• Humid/corrosive environments: Select stainless steel valve bodies or nickel-plated models.
• Vibration-prone conditions: Install anti-loosening screws and vibration-damping brackets.
V. Installation & Commissioning Key Points
1. Installation Orientation:
• Align valve body arrow direction with hydraulic oil flow to avoid reverse installation and leakage.
2. Electrical Connection:
• Ground shielded cables at one end to prevent electromagnetic interference (EMI).
• Maintain ≥200mm spacing between input signal cables and high-voltage cables (e.g., motor wires).
3. Commissioning Steps:
• Zero Adjustment: Set input signal to 0 and adjust the zero potentiometer for 0 output pressure.
• Full-Scale Calibration: Set input signal to maximum (e.g., 20mA or 10V) and adjust gain potentiometer for rated output pressure.
• Linearity Test: Verify proportional pressure output at segmented input signals (e.g., 25%, 50%, 75%).
VI. Common Faults & Troubleshooting
【表格】
Fault Symptom Possible Causes Solutions
No Pressure Output Power disconnected, amplifier failure Check power supply, replace amplifier
High Pressure Fluctuation Oil contamination, spool sticking Replace filter, clean spool
Slow Response Poor signal contact, low gain setting Reconnect wires, increase gain value
Severe Leakage Seal degradation, valve body cracking Replace seals, return for repair
Overheating Prolonged high-pressure operation, poor cooling Add cooling module, reduce system pressure
VII. Maintenance Recommendations
1. Regular Inspections:
• Check filter differential pressure every 500 hours; replace if exceeding 0.35 bar.
• Replace hydraulic oil every 2000 hours (recommend ISO VG46 anti-wear oil).
2. Long-Term Storage:
• Clean valve body surface and apply anti-rust oil.
• Position spool at neutral and wrap ports with plastic film for dust protection.
3. Spare Parts Management:
• Critical spares: Proportional solenoid, main spool, O-rings.
• Inventory cycle: Replace seals every 2 years (even if undamaged).
