SE1012 SE1013 High Speed Punch Servo Valve | SE1012-40-1106 SE1013-ET-1301 | CNC Punch Fast Valve

The SE1012 and SE1013 Series high-speed servo-proportional fast valves from Chengyuan Hydraulic are premium control components specifically engineered for CNC punch presses and high-speed shearing systems. Fully compatible with Tokimec (Tokyo Keiki) and Amada machinery standards, this series includes critical models such as SE1012-40-1106 and SE1013-ET-1301. As the “brain” of the punch hydraulic system, these valves integrate highly sensitive solenoids with precision-ground spools to ensure zero-drift stepping accuracy during ultra-high-frequency punching. Every SE series valve undergoes 100% simulated load testing, validating thermal stability under conditions exceeding 1000 hits per minute, ensuring 100% original-place interchangeability.

Key Technical Advantages:

• Ultra-Fast Dynamic Response: The SE series optimizes the spool mass-to-power ratio, achieving response frequencies near 100Hz. This millisecond-level reaction time is the cornerstone for “high-speed short-stroke” continuous punching, drastically increasing manufacturing throughput.

• High-Precision Wear-Resistant Spool: The spool and sleeve undergo cryogenic treatment and high-frequency quenching, followed by secondary grinding. This extreme fit precision minimizes internal leakage and ensures dead-zone characteristics remain stable even after hundreds of millions of cycles.

• Anti-Vibration Structural Design: Engineered for the severe hydraulic pulses inherent in punch systems, internal feedback mechanisms and coil packaging are reinforced. This prevents signal distortion or coil failure caused by high-frequency vibration, extending the Mean Time Between Failures (MTBF).

• 100% Drop-in Interchangeability: Electrical pinouts, mounting patterns (ISO 4401 compliant), and porting are identical to original Tokimec SE series specifications. Users can replace original valves without modifying controller parameters or physical piping, minimizing downtime costs.

Application Areas:

• CNC Punch Presses: Hydraulic head control for Amada, Nisshinbo, and LVD machines.

• Metal Forming: High-speed synchronous press brakes and high-speed shears.

• Industrial Automation: Any dynamic servo system requiring extreme switching frequencies and linear flow control.

Expert Maintenance Tips:

• Strict Filtration Standards: Servo valves are highly sensitive to particulates. Maintain a precision filtration rating of 5μm or better to keep oil cleanliness within NAS Grade 6, preventing spool sticking or erosion.

• Air Bleeding Procedure: After installation or maintenance, air must be purged via the top bleed screw. Trapped air can lead to system oscillations, excessive noise, and sluggish response.

• Voltage Stability: Ensure the DC 24V control power supply is stable (within ±5% fluctuation). Unstable voltage directly compromises the spool positioning accuracy and dynamic performance.
