WKM Dynacentric 04-B5123-02-S02-11/HL butterfly valve is used to isolate or regulate the flow of a fluid in high-pressure water, oil, steam, gas and slurry applications. The drop-tight sealing capabilities of this valve make it an excellent selection for vacuum service.
Features:
- This quarter-turn valve is fully open or closed when the disc (positioned in the centre of the pipe) is rotated a quarter turn.
- It utilises a handle actuator that allows opening / closing of the valve orifice by rotation of the central disc.
- It is facilitated with a lower stem disc spring to allow proper thermal expansion and provide constant grounding.
- It incorporates a thrust bearing and disc spacer to reduce body wear and ensure positive disc centring in the valve bore.
- This lug-style butterfly valve has threaded tapped lugs, positioned on the valve flanges for secure bolt connections and is suitable for end-of-line service.
