Product Overview

A flexible wedge is a one-piece and fully guided cast with a central hub allowing the seating faces to move reciprocally and thus compensating for the distortion on body seats due to thermal expansion or pipe loads.
Seat ring and wedge seating face are set to 9°angle from the vertical to minimize the sliding contacts between wedge and seat ring while opening or closing them.
Wedging helps lead to a tight seal in a low differential pressure service.
A flexible wedge resists wedge sticking or binding in a service. The wedge may be closed in a hot condition and opened in cold. The seating surface are stellited to provide high cycle capability in a very high differential pressure service.
