The truck turn slide valve and its weatherproof cover form a unit, which can be built into new or existing aluminium or steel bulk material containers (min. Ø 2400 mm).

A special mechanism generates a rotary movement of the slide plate when the valve is opened or closed, thus preventing bulk material from getting between the sealing surfaces. The metallic sealing surfaces are always in contact to each other – irrespective of the valve’s position. The sharp-edged slide plate removes any deposits on the sealing surfaces. The sealing is ensured by pressure from the inside, i.e. detachment under pressure is not possible. Therefore – and by eliminating the need to enter the truck or rail wagon – safety is significantly increased.
