Frequently asked questions
Common questions about Solenoid Valve from 3G Electric.
How do I choose between normally open and normally closed solenoid valves?
Normally closed valves stay shut until energized, making them fail-safe for most fluid control. Normally open valves are used where flow must continue on power loss, such as cooling circuits. Consider your system's fail-safe requirement and the media's pressure range.
Are ASCO and REDHAT solenoid valve coils interchangeable?
ASCO and REDHAT coils are often designed for specific valve bodies, but many share common voltage and mounting standards. Check the coil's voltage, frequency, and connector type against your valve's requirements. Our catalog lists compatible coils and repair kits for each series.
Can you source solenoid valves for refrigeration applications?
Yes, we stock refrigeration solenoid valves from brands like RANCO and ASCO, designed for liquid line and hot gas applications. These valves handle refrigerants and operate reliably at low temperatures. Specify your refrigerant type and line size for accurate selection.
