Selecting the Right Valve by Service: Typical Piping Segments in Water and Industrial Lines
Where do resilient-seated gate valves and industrial gate valves get used, and under which media and pressure conditions? Compare by medium, pressure class and actuation so overseas buyers can match their own project conditions.
City Water Trunks and Distribution Hubs
Potable water mains typically use PN16 resilient-seated gate valves with EPDM seats for zero leakage. Buried installations need corrosion protection, and valves flange to fittings with RF flanges.
WWTP Influent, Effluent and Settling Tank Piping
Influent and reuse lines use soft-sealed gate valves to isolate media carrying suspended solids. Manual operation or electric actuator options, with corrosion-resistant coating selected to suit the medium.
Fire Protection and Pump House Riser Lines
Fire mains and pump house discharge lines are built to API 6D, with fire-safe and antistatic design per API 607. Handwheel or worm gear drive options.
F316 Stainless Valves for Corrosive Media
Chloride-bearing or chemical process lines use F316 stainless steel gate valves, rated PN16–PN40, with RF flanged or welded ends.
Irrigation Branch Lines and Water Tower Connections
Irrigation zone branches commonly use wedge double-disc gate valves that allow sand and grit to pass through the seat. Sizes DN50–DN600 matched to the branch line diameter.
