Hydromat DTR Differential pressure regulator with flanges PN 16 with hole circles according to ANSI class 150
DN 150 - 6, nominal value 400-1800 mbar, cast iron

"Hydromat DFC" Differential pressure regulator PN 16

both ports flanged with hole circle according to ANSI Nominal value: 400 to 1800 mbar, infinitely adjustable

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

All functioning components in one plane.

Oventrop differential pressure regulators are proportional regulators working without auxiliary energy. They are used in existing or new buildings for a local or central regulation of the differential pressure. With the differential pressure in the installation increasing, the valve disc closes down to maintain a constant differential pressure within a necessary proportional band. The differential pressure is set to the required nominal value. The nominal value is infinitely adjustable and lockable. The differential pressure regulators are designed for installation in the return pipe.

Further additional functions: Isolatiion, filling and draining

The regulators are supplied complete with connection set (capillary length 1 m).

Lengths according to DIN EN 558-1, basic series 1.

Bonnet made of bronze, stem made of brass resistant to dezincification (DZR), disc made of stainless steel with EPDM seal. Maintenance-free stem seal du to double O-ring made of EPDM.
