To control cooling circuits. To open and close inlets and outlets.
In power plants a wide range of valves is used. VAG valves can also be found in a power plant’s frequently extensive peripheral systems: In the cooling-water inlet and outlet structures penstocks are installed because ruggedness and a high degree of tightness are asked for here. Butterfly valves protect the water supply of the pumping stations and the downstream pipelines. In combination with a brake-and-lift unit they are indispensable for the protection of the valuable main cooling water pump. Whether as customised types for district heating pipelines or in man-sized dimensions with accident prevention safety interlock – butterfly valves can be found everywhere in the system thanks to their versatility. Plunger valves allow the precise control of the flow rate and the pressure of the water discharged. Hydrants, whether of the conventional or the underground types, ensure immediate access to water for fire fighting by the fire brigade and security staff. Air valves ensure speedy pressure compensation of the feed- and exhaust air in fire-water systems.
As a pioneer in valve technology, VAG makes an essential contribution to the evolution of rugged and safe valves. Because in the cooling system of large-scale steam power plants reliability and safety have absolute priority.
In the cooling-water or district heating system. In pumping stations or storage tanks. For fire-fighting systems or water treatment plants. In all those areas of power plants, diverse valves are used. The VAG EKN® Butterfly Valve offers reliability, quality and durability. The VAG CEREX® Butterfly Valve is the suitable valve for treatment plants and fire-water pipelines. By its patented system, the VAG EROX® Penstock ensures absolute tightness when it is used to shut off cooling tower wells and inlet channels. You will receive all these valves from one single source of supply – VAG.
