Marine Vented Loops
The 20013 Marine Vented Loop provides a proven way to break the vacuum in marine water systems. Back siphonage will be broken if the loop is approximately two feet above water level.
The Vacuum Breaker has a normally closed poppet which keeps vent line fumes from the vessel. The breaker is designed for a corrosion proof service life with a protected air vent. All of the parts exposed to liquid are manufactured from Delrin. The external poppet spring is stainless steel. Liquid never touches the stainless steel spring. The vacuum breaker has a low vacuum breakaway. Pressure on the inside of the loop keeps the breaker closed. The soft, resilient seat gives quiet, trouble-free operation. The spring action provides a quiet opening and closing operation. Air goes in – never out
