Safety shut-off valve
Full-vacuum chlorinators in accordance with DIN 19606 are designed to a high safety standard. Even if the dosing lines are damaged, no chlorine gas escapes; only ambient air is sucked into the vacuum system. In the event of a fault in the vacuum regulator, a safety relief valve relieves the pressure in the vacuum system by opening at the slightest overpressure and directing the chlorine gas to the gas detector.
However, if by unfortunate coincidence a defective vacuum line and a leaking inlet valve occur at the same time, the safety blow-off valve cannot respond because no overpressure builds up due to the defective vacuum line. The chlorine gas escapes uncontrolled elsewhere. The safety shut-off valve prevents this and thus ensures the highest possible level of safety for the full-vacuum chlorinator. At the same time, the shut-off valve prevents water from entering the vacuum regulator in the event of a leaking injector non-return valve.
The safety shut-off valve is required by DIN 19606 in all installations in which the injector is not located in the chlorine gas compartment.
Features & advantages
- Blocks the vacuum line if the vacuum is too low
- Protects the vacuum regulator from water from the injector
