Triple offset butterfly valves – VEXVE

Principle of operation and design
The valves are manufactured according to EN448. The three-eccentric valve design ensures minimal friction and tightness even at high temperatures and pressures.

Nominal diameter:
From DN 300 up to DN 1600

Nominal pressure:
PN25

Working temperature:
from -40˚С up to +200˚С (+250˚С)

Body material:
carbon steel fully welded construction

Gasket materials:
Metal – Metal

Connctions:
• On welding according to EN (DIN) or GOST (GOST)
• On flanges (option)

Applications:
Central heating, hot water (Other on request)

Applications:
• Manual with reducer
• Movement powered by electricity
• Hydraulic drive

Pressure difference:
ΔР = 16 bar or ΔР = 25 bar

Advantages:
• Wide range of sizes: from DN300 to DN1600
• Regulating and locking function
• Maximum working temperature up to 200˚ C with the possibility of higher parameters.
• Tri-eccentric design, guaranteeing a long service life.
• Saddle with a special construction that protects it from contamination and injury.
• Replaceable saddle.
• Airtightness in both flow directions (the valve does not have a specific installation direction) with level of tightness “A” according to DIN EN 12266-1 (1 according to DIN 3230) – zero leakage in both directions or “B” acc. EN12266-1
• Seal type: metal to metal
• High Kv coefficient values
