TruDesign® Vented Loops – With Solenoid

Designed and made in New Zealand, TruDesign Vented Loops with Solenoid are the superior composite siphon break solutions or marine applications. Vented Loops prevent water siphoning from underwater skin fittings back into a vessel and thereby guard against accidental flooding and sinking. Vented Loops are used predominantly in toilet to overboard applications, toilet inlet applications and holding tank to overboard applications. They can also be used in genset or small engine inlet cooling water systems. A Solenoid controlled Vented Loop allows the vent to be switched to fully closed. Used in electric toilet applications where the inlet flush button is synchronised to turn the vented loop solenoid “off”. This enables a full flow of flush water without air being admitted. This eliminates air entering the system as occurs with a standard vented loop. The solenoid used is normally open, requiring power only to close the valve.
