This manual on-off valve is an addition to the series DB Mini providing a simple way to regulate the pressurisation and venting of pneumatically operated machines. It is designed for use in production systems where the focus is on simplicity and minimising costs. Intuitive operation is achieved with the blue-coloured slider as frame, which is an integral part of the housing while encompassing it at the same time. When the valve is closed, the frame also offers the option of locking it.
