Patented Two direction valve geometry

The Solent & Pratt Triple Offset Segment Valve utilizes the well established patented valve geometry where the shaft is offset from the body in two directions (1) and (2), whilst the disc is a segment taken from a cone where the apex is offset from the center line of the valve (3). The disc (segment) of the valve houses a field replaceable metal laminate seal whilst the field replaceable seat ring is housed in the body of the valve.

Due to the valve geometry there is no interference or rubbing between seat and seal as the valve strokes through it’s full 90°.
