Installation Steps
-
Pre-installation Preparation
- Ensure air supply pressure is within the valve's operating pressure range
- Verify air supply is filtered (40μm or finer)
- Check valve model and specifications match system requirements
-
Installation Process
- Select appropriate installation location ensuring easy operation
- Use suitable sealing material (e.g., PTFE tape) on threaded connections
- Install valve into pneumatic system using appropriate tools
- Ensure secure installation to prevent air leakage
- Connect control lines to corresponding ports:
- Port P: Supply port
- Port A/B: Outlet ports
- Port R/S: Exhaust ports
-
Post-installation Check
- Inspect all connections for tightness
- Ensure valve position in system is protected from external mechanical damage
- Verify operating handle moves freely without binding

Operation Guide
-
Basic Operation
- Push-pull operation: Directly pull or push the operating handle to change valve state
- Single head double position: Handle has two stable positions corresponding to the valve's two operating states
- Apply moderate operating force to ensure smooth operation, avoiding excessive force
-
Status Indication
- Determine valve operating status based on handle position
- Monitor system pressure changes to ensure proper valve operation
-
Operation Precautions
- Avoid excessive force during operation to prevent valve damage
- Regularly check for smooth valve operation
- Avoid use in environments with vibration or impact; if unavoidable, take protective measures
