VAG HYsec Hydraulic Brake-and-Lift Unit

El Corado Dam in Colombia: more than 50 valves installed and successfully put into service

Whenever required, VAG’s Technical Service is on duty locally to take care of VAG valves – all over the world, at any time and always highly reliable. This was the case in 2012 in the context of a large-scale project implemented in La Guajira Desert in the north of Colombia, where e.g. a VAG EKN® Butterfly Valve with a VAG HYsec Hydraulic Brake-and-Lift Unit was installed and put into service.

More than 15 VAG EKN® Butterfly Valves for locks overhauled in a clocked cycle exchange

Big dimensions mean big challenges – especially if a tight schedule has to be met because the waterways concerned have to be blocked. To make matters worse, the butterfly valves were installed with vertical shafts. After more than 30 years of reliable service, the DN 1600 butterfly valves were overhauled, fully meeting all the requirements. An additional flame-spray coating on the disks now protects them from cavitation damage during the opening and closing of the valve.

Continued reliability of VAG RKV Plunger Valves in a power plant – even at high pressure

The VAG DN 800 plunger valves supplied in the mid-1980s and suitable for especially high pressures (PN 64) were refurbished step by step after many years of successful service: The corrosion protection was renewed and improved – by way of a PATIG coating – the guide skids were replaced and the gear underwent a general overhaul.
