Siphon break valve CR-brass loop
Siphon break valve CR-brass loop
Robust vent loop made of CR brass (CW602N), nickel-plated. The brass loop features BSP internal threads for pipe connection and drilled lugs for screw fastening. All variants are equipped with a ½" BSP internal thread at the top of the bend to accommodate a suitable vent valve, which can be ordered separately as an accessory. The material is resistant to dezincification and offers high corrosion resistance in seawater.This component is used in seawater-cooled exhaust systems as well as in inlet and outlet lines of marine toilets, particularly when installations are located below the waterline or may drop below it due to heeling or rough sea conditions. The vent loop should be integrated into the pressure side of the line at least 20 cm above the theoretically maximum heeled waterline. For inlets, it is also important that the vent loop is installed on the pressure side, downstream of the intake pump.The vent valve and suitable connection fittings – such as hose tails – are available separately. They are not included in the scope of delivery and can be found in the accessories range.For marine toilets, we recommend for example the brass hose tail 1964-019 for 19 mm hose connection (inlet) and 1964-132 for 38 mm hose connection (outlet) as suitable connection fittings.Thread type: BSPThread form: cylindrical, i.e. parallelThe thread sizes are nominal sizes and do not represent the thread diameter.
