Overflow valves fitted with a PTFE back seal.
AWP UVR overflow stop valves are a mechanical regulating system. The adjustable pressure range is 2 to 8 bar. The stem is used to close the valve. The valve is fitted with a PTFE back seal. This allows the stem sealing system (screw bushing) to be changed during operation. The damping system prevents “flattering” at low flow rates. The valve is back pressure dependent. AWP overflow valves are suitable for installation as relief valves in the refrigerant cycles of industrial refrigerating plants. Overflow valves are safety devices for protecting the refrigerating plant or its components from excess pressure (see also DIN 8975 part 7). They comply with the technical regulations of the German Technical Control Board (TÜV).
