Applications
- High-purity corrosive chemical handling
- All semiconductor wet etch and clean (WEC) process chemicals
- Chemical line sizes 3/8" or smaller
Specifications
Durable Valves for Harsh Environments
- With no exposed metal hardware, the CR4 Series valve is completely sealed and protected from harsh chemical environments
- The modular design enables manifold customization into your fluid delivery system
- Designed with the same footprint as our stand-alone and manifold Galtek® SG Series valves and Dymension® valve manifolds, allowing for easy retrofits or replacement
