1. Product Overview
1.1 Product Name
Safety Dual Valve for Punch Press Machines (Model: SK23JSD-L/XXX)
1.2 Functional Description
The Safety Dual Valve boasts an advanced dual-redundancy design, incorporating two independent pneumatic channels. This ensures instant power source cutoff during emergency stops, operational errors, or if a single valve fails, thereby safeguarding both personnel and machinery.

3. Installation Instructions
3.1 Pre-Installation
- Ensure that the air supply is pristine, dry, and free from any oil or contaminants.
- Verify that the valve model is compatible with the machine's pneumatic interfaces.
3.2 Installation Procedure
1. Mounting: Securely mount the valve vertically in the designated spot on the press pneumatic control panel using M6 bolts for optimal stability.
2. Pneumatic Connections:
- Main Circuit: Connect the air supply to inlet (P) and link the actuator (e.g., cylinder) to outlet (A) seamlessly.
- Redundant Circuit: Independently configure the backup channel to prevent any cross-interference effectively.
3. Electrical Wiring:
- Solenoid Coil Voltage: Accepts DC24V±10% or 110V/220V. Specify requirements in advance. (Red: +, Black: -)
- Ensure a reliable ground wire connection to the equipment's earthing terminal for safety.
4. Operating Procedures
4.1 Pre-Operation Checks
- Ensure the manual reset button is set to the "ON" position.
- Engage the test button to simulate an emergency stop and confirm dual-channel synchronization effectively.
4.2 Normal Operation
- Both valves operate in unison during normal function. A failure in either channel activates a red alarm light and automatically engages the backup.
4.3 Emergency Stop
- Activate the E-stop button to cut off the air supply synchronously, bringing the press slide to an immediate halt.

5. Maintenance
5.1 Routine Maintenance
- Conduct weekly cleaning of the valve surface and inspect air hose connections for possible leaks.
- Test the response time monthly and meticulously record the data for accuracy.
5.2 Periodic Service
- Replace seals biannually; cleanse the spool with anhydrous ethanol for optimal performance.
- Undertake annual professional calibration of solenoids and sensors to maintain precision.
6. Troubleshooting
Symptom Possible Cause Solution
Valve Inaction: When the power is off or there's a coil burnout, ensure seamless operation by checking wiring and replacing the coil as necessary.
Air Leakage: If you encounter seal degradation or notice loose fittings, restore optimal performance by replacing seals or tightening fittings for a secure fit.
Delayed Response: Experience a swift response by addressing low pressure or spool blockage. Increase pressure or clean the spool to maintain efficiency.
7. Safety Warnings
- 1. Safety First! NEVER attempt to disassemble the valve while it's under pressure. Always ensure the valve is depressurized before any servicing.
- 2. Precision Matters: Internal adjustments should only be handled by authorized personnel to ensure safety and optimal performance.
- 3. Stay Alert: Immediately initiate a shutdown if you detect any abnormal noise or unexpected leakage, safeguarding your operations.
