The K-KFK-C type ball valve consists of a 2-piece body with a flange screwed or flanged on one side. Due to the design, the flow direction must be observed when using the ball valve as an end fitting. Up to nominal size DN 25, the stem is mounted from the outside by means of a screw connection. The screw connection used allows for easy replacement of the stem packing. Stem packing according to TA-Luft regulations is standard from nominal size DN 32 or can be installed up to nominal size DN 25 at an additional cost upon request. Actuators can be attached using a mounting kit. This retrofitting capability is available as standard.
