Āhuatanga matua:
- Product durability: Sturdy valve body ensures a long service life.
- Te whānuitanga o nga tono: Suitable for household appliances, industrial equipment, and more.
- Convenient installation: Designed for easy installation and maintenance, offering reliable accuracy in various environments.
4. Tatūnga me te Tāuta
Follow these steps for proper installation of your pneumatic solenoid valve:
- Whakaritenga: Ensure the air supply is turned off and depressurized. Gather all necessary tools and fittings.
- Whakapiki: Securely mount the valve to a stable surface using appropriate fasteners. Ensure the valve is oriented correctly according to the desired flow direction.
- Pneumatic Connections: Connect the air supply lines to the designated inlet and outlet ports. Use thread sealant on all threaded connections to prevent leaks. Refer to the markings on the valve body for port identification (e.g., P for pressure, A/B for output, R/S for exhaust).
- Hononga Hiko: Connect the electrical wiring to the solenoid coil terminals. Ensure the voltage matches the valve's specifications (e.g., 24VDC for AG-3021-24VDC). Consult a qualified electrician if unsure.
- Whakamātautau: Once all connections are secure, slowly restore the air supply and electrical power. Test the valve's operation by applying the control signal. Check for any air leaks or electrical issues.
5. Nga Tohutohu Whakahaere
The EJWFASCV Pneumatic Solenoid Valve operates by receiving an electrical signal to control the flow of compressed air.
- Mahi Pūnoa: When the appropriate electrical voltage is applied to the solenoid coil, the valve will shift its internal mechanism, allowing air to flow through the designated ports. When the voltage is removed, the valve will return to its default position (typically closed or exhausting).
- Whakakore a-ringa: Many models, like the one shown in Figure 1, include a manual override lever or button. This allows for manual actuation of the valve for testing or emergency situations without electrical power. Use the manual override carefully and ensure the system is depressurized if necessary.
- Control System Integration: Integrate the valve into your control system (e.g., PLC, relay circuit) by connecting the solenoid's electrical terminals to the appropriate output. Ensure the control signal duration and frequency are compatible with the valve's specifications.
6. Tiaki
Regular maintenance helps ensure the longevity and reliable performance of your solenoid valve.
- Tirotiro: Periodically inspect the valve for any signs of wear, damage, or leaks. Check pneumatic connections for tightness and electrical wiring for integrity.
- Te horoi: Keep the valve and its surroundings clean. Dust and debris can affect performance. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or solvents.
- Kounga rangi: Ensure the compressed air supply is clean and dry. Contaminants in the air can cause internal damage to the valve. Consider installing air filters and dryers upstream of the valve if not already present.
- Whakahinuhinu: Most modern pneumatic valves are designed for non-lubricated air or are pre-lubricated for life. Consult the manufacturer if lubrication is required for your specific model.
