Operating challenges
- Corrosion-resistant coating system
- Suitable seat and elastomer selection
- Large-diameter operability
- Buried or inaccessible service requirements
- Water-hammer and non-slam considerations
Operating context
Translate process conditions into valve requirements
Potable-water, treatment and sewage systems require suitable elastomers, coating, corrosion protection, low operating torque, maintainability and hydraulic performance across small and large diameters.
All constructions, pressure-temperature limits, certifications and inspection requirements must be confirmed against the specific product and purchase specification.
Relevant valve families
- Butterfly valves
- Gate valves
- Check valves
- Ball valves
Materials & standards review
- Ductile iron, carbon steel and stainless options
- Epoxy or project-specified coating
- AWWA / EN / project product requirements as applicable
- Potable-water approvals only when explicitly required
- Flanged, wafer, lugged or buried-service interfaces
