Overview
The NIBCO LCS-6822 is a premium 1″ butterfly valve designed for industrial flow control and isolation. Built with CF8M stainless steel body and 17-4 stainless steel shaft, this 285 PSI-rated valve delivers reliable performance in corrosive and high-temperature environments. The lug-style design supports both isolation and throttling applications across HVAC, hydraulic, plumbing, and mechanical systems.
Key Features
- Quarter-turn (90-degree) operation for fast, simple open/close control
- Internal stem/disc splined drive eliminates pins and bolts, preventing leak paths
- Ductile iron disc with EPDM encapsulation for extended service life
- Extended neck design allows insulation thickness up to 2 inches
- CF8M stainless steel body resists corrosion and scaling
- 17-4PH stainless shaft provides superior strength and longevity
