Pressure relief valves VPH/VRH
Reliable valves for pressure relief
The relief valve is used for protecting the components of a system against overload as a result of a pressure peak. Further, the valve is designed for controlling/limiting the system pressure by draining off the surplus water from the pressure side. The valve is designed for tap water and ultra-pure water, i.e. without additives of any kind to the medium. The relief valves are used in several applications: fire fighting and humidification systems, etc.
The Danfoss APP pumps are available in various sizes from 0.6 m3/h to 86 m3/h for use in small and medium-sized SWRO facilities. See the product program below
