Low-pressure ball valve NSKA-C

Technical Description

The NSKA-C type ball valve consists of a forged body with a connector screwed in on one or both sides. The stem is blow-out proof. Up to nominal size DN 25, the stem is mounted from the outside by means of a screw connection. This screw connection allows for easy replacement of the stem seal. A stem seal according to TA-Luft regulations is available as standard from nominal size DN 32 or can be used up to nominal size DN 25 upon request at an extra charge. Actuators can be mounted from nominal size DN 32 using a mounting kit. This retrofitting capability is available as standard.
