EMCO Classical Venturi Tube Welded Sheet With Weld end or Flange Connection KVR

Manufactured by  

EMCO classical venturi tubes are used as primary elements in flow measurement of steam, liquid and gas according to the differential pressure principle.

Design standards :

• ISO 5167-4, ASME MFC-3M
• Sizes : DN 200 - 1200 according to ISO 5167
• Bore/diameter (β) : 0,4 ≤ β ≤ 0,7(ISO 5167), 0,3 ≤ β ≤ 0,75 (ASME)
• Pressure rating : PN 10 - 100, 150 - 600 lbs, ISO PN 20 - 100
• Material : Carbon steel, AISI 316, others on request
• Mounting style : Weld ends according to DIN 2559 or ANSI B16.25. Flanges acc. to DIN or ANSI B16.5 standards or Clamp connections, like Grayloc
• Pressure taps : Weld ends Ø 21.3 mm, 26.9 mm, thread connection 3/8", 1/2" BSP male, 1/2" NPT
• Tappings : Single pressure tappings or 2x4 tappings each arranged with an external annular ring to equalise the pressure
• Outlet cone : 7 - 15°

Technical Data

• Accuracy : 1,5 % (according to ISO 5167-4)
