The manual on-off valve is an addition to the DB Mini series. It provides an easy way of regulating the pressurization and exhausting of machines operated using compressed air. It is designed for use in production systems where the focus is on simplicity and costs. Intuitive operation is achieved with the blue coloring and the shape of the slide. This forms a frame that both encompasses the housing and is part of it. When the valve is closed, the frame also enables the valve to be locked.
