The block and control valve WAK is an economical design suitable for many duties. The streamlined disc moves smoothly without flutter. When the valve is closed the disc is pressed tightly against the seat which is incorporated into the body. Opening and closing are free of friction and jamming.

The sealing system is completely integrated within the body utilizing the conventional ADAMS laminated metal/graphite sealing. The WAK is a general purpose valve for many applications involving fresh water, seawater, sewage, hydrocarbon and wet gas. Our block and control valve type WAK is well-proven, many of them are still in use after several decades.
