The Series 681 is a particularly robust pressure reducing valve in all-metal design, which has proven itself not only in drinking water applications but also in harsh operating conditions in industrial applications or in cases of fluctuating environmental temperatures. This pressure reducing valve is also suitable for hot water applications. Stability and reliability: The set outlet pressure at zero-usage is held constant even in the case of greatly varying inlet pressures.
The Series 681 Pressure Reducing Valve allows the protection of:
Pressure reducers are used, if within a piping system despite of varying pressures on the inlet side a certain pressure must not be exceeded on the
