The physical effect that liquids in motion tend to freeze to a lesser extent forms the basis of both versions. Therefore, both the weep as well as the freeze stop version let water pass through the valve (in case of different pressures and under the circumstances) even if the spray gun is closed in order to keep the water which is in piping, hose and spray device in motion.The weep high pressure spray guns let a reduced water quantity pass through even if the trigger of the gun is not pulled as there is a notch in the seal seat of the valve. This is ensured in high pressure when the high pressure pump is in operation as well as in low pressure in case of water pipe pressure.The so called freeze stop spray guns are equipped with a valve in valve technology. The operating valve which is driven by the spray gun trigger includes the real automatically operating freeze stop piston. For cleaning applications the spray gun is opened and closed as usual by the operating valve. The integrated freeze stop valve only comes into operation when there is low pressure (water pipe pressure). It is opened in a spring driven way if the pressure is lower than 5 bar. If the pressure increases e.g. by switching on the high pressure pump the freeze stop valve closes automatically. This improves the comfort of washing as there is no water coming out of the gun when taking it out of the lance holder.What is the difference between the versions freeze stop and weep?weepfreeze stopR+M Nr.200 301 050R+M Nr.200 300 1001/4\Repair kit ST-301ST-301 swivels Seal kitsST-1100R+M Nr.201 100 401201 100 403** Year of manufacture from 2016
