Область применения

Suitable for non-corrosive and corrosive gases, vapors and liquids; permissible operating temperature -10 to +570 °C.

Дизайн

One-piece orifice plate, orifice disk form A, B or D (see types of primary differential pressure devices in "Technical description", "Function"); see Ordering data for materials.

Overall length

40 mm to DIN 19205

Nominal diameters

EN: DN 50 to DN 500

ASME: 2 inch to 20 inch

Nominal pressure

EN: PN 6 to PN 315

ASME: class 150 to 2500

Sealing face to the mating flanges

Plane, sealing face turned, N10/N12 to DIN ISO 1302
Plane, sealing face turned, N8 to DIN ISO 1302
Plane, RF (raised faced) for versions to ASME

Tapping sockets

With connection thread G½ DIN ISO 228/1, with connection dimensions to DIN 19207 form V
With threaded connection ½-14 NPT male, for version to ASME
With Ø 12 mm pipe connection for pipe union with ferrule
With welding connection, Ø 21.3 mm

Connection size

The connection size depends on the operating pressure, the temperature of the medium (DIN 19207 and 19211) and the medium, e. g.

For liquids and gases
- up to PN 160: Thread G½ or welding connection Ø 21.3 mm
- from PN 6 and PN 400: Welding connection Ø 21.3 mm
- > PN 400: Welding connection Ø 24 mm
For steam
- up to PN 100: Thread G½ or welding connection Ø 21.3 mm
- > PN 100: Welding connection Ø 24 mm

See "Technical description" and "Function" for position of the tapping sockets.
