مشخصات:
Pressure fluctuations in a water distribution circuit can cause a reversal of the flow direction. In this case a check valves, installed between the water distribution system and the mains water supply, closes automatically and prevents any back flow, back suction or back pressure. The inspection openings provided before each backflow preventer unit, allow a regular monitoring of the safe functioning of the component.
The series 49.0xx.x26, verifiable check valves, types EA and EC , is developed according to the performance requirements of DIN EN 13959 and are confirmed by an accredited laboratory. These are suitable, according to DIN EN 1717, for securing devices using category 1 and 2 liquids (according to WRAS the EC type is also applicable to fluid category 3).
Also check valves protect sensitive equipment from contamination from backflow (e.g. behind pumps), dry running through retention of water (e.g. before not self-priming pumps), cross flow in systems with varying line pressure (e.g. in parallel cold and hot water supplies ) and ensure the flow in only one direction in complex fluidic systems.
The verifiability offers the user the possibility of checking the operational reliability and can, optionally, be equipped with a manometer or other sensors.
Various configurations by combining different nominal orifice sizes and fluid connectors are available.
