Main applications
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
Butterfly Valves from Finland
• Full bore • Lightweight • Designed according to EN488 • Maintenance free structure • CE-marked • High-quality pressure vessel steel
Welding seams: All welders have qualification (EN 287 and 1418) According to PED Quality requirements according to EN 3834-2 All welding seams have own welding manuals (destructive examinations) Non destructive testing, 100% visual check (EN970) Penetrant testing (EN 571-1) Radiographic testing optional

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)

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.
Extension pipes are recommended for trouble free installation
Bypass valve is recommended to protect the pipeline against pressure shocks – the valve itself does not need that.
