  1. KeepEnergy Under Control Jouko Riihonen ExportManager Vexve Oy

  2. VEXVE: • Vexve Ball & Butterfly valves • Vesiverto Water Metering Systems - Vexve Controls Heating controllers & regulators We save energy!

  3. All Vexve valves are designed for District Heating Pipelines District Heating Steam Oil Main applications The only modern Butterfly Valve designed for DH & DC pipelines!

  4. Butterfly Valves from Finland • Metal seated • Dimensions DN 300 – DN 1400 • Body class PN 25 • Trim class PN 25 and PN 16 • Temperature -40 C - +200 (250 C) • Welded and flanged end connections

  5. Butterfly Valves from Finland • Full bore • Lightweight • Designed according to EN488 • Maintenance free structure • CE-marked • High-quality pressure vessel steel

  6. Butterfly valve weldings • Welding seams: • According to PED • Quality requirements according to EN 3834-2 • All welders have qualification (EN 287 and 1418) • All welding seams have own welding manuals (destructive examinations) • Non destructive testing, 100% visual check (EN970) Penetrant testing (EN 571-1) • Radiographic testing optional

  7. Traceability • Individual valve numbers • Individual manufacturing reports

  8. Pressure testing of butterfly valve • Every valve is tested both sides according to EN 12266-1: • W1 valves seat test with 18bar • Leakage rate A • W2 valves seat test with 27,5 bar • Leakage rate A • Bodytest W1 and W2: 38bar (180s) No valve leaves the factorywithoutchecking!

  9. Vexve Full Bore Butterfly Valve Design It is a Full Bore Design

  10. Temperature and Pressure Range/Curve Designed for DH-pipelines!

  11. Difference between shut-off and control valve Graphite packing BFS/BRS O-rings: Viton 0…+200oC NBR -40…+70oC BFC/BRC (-40…+250oC)

  12. KV values of butterfly valves Kv = valve flow coefficient Q = volumetric flow rate [m3/h]  p = pressure differential across the valve [bar] Full open butterfly valve: KV value and hydraulic resistance coefficient (z) Approximately 50% better than old type butterfly valves!

  13. Ball vs. Butterfly Prices Inexpensive, lightweight, class A, bi-directional…

  14. Assembly of the butterfly valve • Valve has been designed for pure liquid • => The pipeline should be clean and flushed! During the flushing, the valve opening should be about 5 degree. Pressure shocks should be avoided. Pipeline maximum test pressure: 38bar (the valve is opened) 27,5 bar (the valve is closed) Blind flange should be always welded after the valve if the pipeline ends and it should fulfill with air removed water. And make sure there is no oxycen in water!

  15. Welding Extension pipes are recommended for trouble free installation And PLEASE read the Manual! Bypass valve is recommended to protect the pipeline against pressure shocks – the valve itself does not need that.
