Product Description
- The pressure reducing valves in the 681 series offer reliable protection for domestic water supply systems as well as commercial and industrial systems against excessive supply pressure.
- Pressure reducing valves are used when a certain pressure must not be exceeded on the outlet side of the pipework despite different pressures on the inlet side.
- The 681 series is ideally suited for use in drinking water supply in accordance with DIN 1988, in industrial and building services water supply, in snowmaking systems, in fire extinguishing technology and sprinkler systems, as well as in shipbuilding and offshore installations.
- This pressure reducer is extremely robust in a solid metal design for water and air.
- The Series 681 pressure reducing valve has proven itself not only in the drinking water sector, but also in harsh operating conditions in the industrial sector or in fluctuating ambient temperatures.
- This pressure reducer can also be used in the hot water sector.
- The pressure reducer impresses with its stability and reliability: the set outlet pressure with zero tapping is kept constant even with strongly fluctuating inlet pressures.
