Designed and made in New Zealand, Tru-Design Vented Loops with Solenoid are the superior composite siphon break solutions for marine applications. Vented Loops prevent water siphoning from underwater skin fittings back into a vessel and thereby guard against accidental flooding and sinking.
These vented Loops are used predominantly in toilet to overboard applications, toilet inlet applications and holding tank to overboard applications.
A Solenoid controlled Vented Loop allows the vent to be switched to fully closed. 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. Vented Loops are moulded from a glass reinforced nylon composite. High strength, high-modulus glass fibres impregnated into the nylon provides dramatic strength, stiffness, toughness, and dimensional stability to our loops.
- Robust polymer covered solenoid allows for a long life in the marine environment
- Diaphragm valve provides faster breaking of siphon due to larger flow rate available
- Female threaded Solenoid Valve, no brass/bronze adapter to corrode
- Constant internal diameter ensures no reduction in flow
- 3 screw mounting posts give secure and easy installation
- Solenoid valve is supplied with flying leads for easy installation
