The KSAE-DR-C ball valve consists of a block or forged body with a screw-in connection piece with external thread on both sides, including SAE flanges. Due to the threaded connection between the SAE flange and the ball valve screw-in piece, the flanges are designed to be rotatable. Up to nominal size DN 25, the stem is mounted from the outside using a screw connection. This screw connection allows for easy replacement of the stem seal. A stem seal according to TA-Luft regulations is standard from nominal size DN 32 or can be installed up to nominal size DN 25 for an additional charge upon request. Actuators can be attached using an mounting kit. This retrofit capability is standard from DN 32. Up to nominal size DN 25, this must be specified when ordering.
