Laddomat® double check valve

The double check valve prevents the accidental self-circulation when connecting charging circuits between boiler and buffer storage tank or between working buffer storage tank and slave-type buffer storage tank.
The valve is equipped with two spring-loaded balls which close off the flow in the pipe when the pumps are not operating.
The flow is different in each flow direction - higher when charging the buffer storage tank to transfer the output from the boiler, and lower when discharging the tank to optimise layering.
