CALEFFI XF WITH BYPASS

Sizes DN 40 (code 577800, 1 ยฝโ€) and DN 50 (code 577900, 2โ€) are equipped with a by-pass
to restrict the flow rate passing through the device and thereby increase the Kv value.

We recommend 100% filtration during commissioning and for the first few weeks of system operation. Then, during the โ€œconstantโ€ phase, the device can be set to operate with by-pass to achieve a higher Kv.
