ELECTRICAL & CONTROL DESIGN STRATEGIES: Solenoid valves can be economical solutions to flow control requirements. And they are easy to maintain. But any electro-mechanical device has limitations.
Here are a few choices that might add to your comfort level when applying solenoid valves:
1 — specify DIN coils and connectors to simplify assembly and reduce installation time
2 — investigate the use of rectified coils if “ac hum” is a concern, especially in residential installations
3 — consider DIN electrical connectors with integral surge suppression to protect control electronics
4 — use lighted DIN connectors to simplify troubleshooting
5 — evaluate magnetic latching coils for battery operation or when heat generated by the solenoid valve coil is a concern.

And be sure to ask your distributor or regional manager about the availability of manual override if valve operation is required when power is interrupted.
