Hydromat DFC Differential pressure control valve with flanges according to EN 1092-2 PN 16
DN 65, nominal value 400-1800 mbar, cast iron


Hydromat DFC differential pressure control valve PN 16

For use in central heating and cooling systems with closed circuits, for operation with non- aggressive fluids (e.g. water or suitable water-glycol mixtures according to VDI 2035).

Oventrop differential pressure control valves are proportional regulators working without auxiliary energy. They are used in old an new buildings for decentralised or centralised differential pressure control. If the differential pressure in the system increases, the valve plug moves to the closed position and thus keeps the desired differential pressure constant according to a necessary proportional band. The differential pressure is controlled to the desired nominal value. The nominal value is infinitely adjustable and blockable. The differential pressure control valves are intended for installation in the return pipe.

All functions accessible from the top.

Further additional functions: Shutoff, filling and draining

The control valves are supplied complete with connection set (length of capillary tube: 1 m).

Body made of cast iron, bonnet made of bronze, spindle made of brass resistant to dezincification (DZR), plug made of stainless steel with EPDM seal. Maintenance-free spindel sealing by double EPDM O-ring.

Nominal value: 400 to 1,800 mbar, infinitely adjustable

Both sides with flanges according to EN 1092-2. Lengths according to DIN EN 558, basic series 1.
