Stargate-O-Port slide-gate valve

The Stargate-O-Port slide-gate valve (or through-port valve) features a well-guided blade — with a hole in the middle — passing through both ends of the valve body. This design offers several advantages. Foreign matter does not get trapped in the bottom of the valve or jammed between the gate and the body. This prevents seat damage so that the valve always seats and seals well. The valve has a class VI shut-off, independent of the pressure differential between upstream and downstream side. Over 97% of the valve’s body thickness is solid material, resulting in a very stiff valve body. Capable of handling pressure shock waves and aggressive flow media, the valve is virtually maintenance-free and can be installed in any position in the pipe since it does not have a preferential flow direction.
