WATER & WASTEWATER
Valve applications across the complete water cycle.
Explore valve duties from raw water intake and treatment to distribution, wastewater and sludge handling.
APPLICATION OVERVIEW
Four critical parts of the water & wastewater process.
RAW WATER INTAKE & PUMPING
Protect pumps and keep raw water moving.
Intake structures and pumping stations need dependable isolation, low headloss and controlled check-valve closure during every pump cycle.
- Intake screens
- Pump suction lines
- Pump discharge
- Surge protection bypass
Frequent starts, reverse flow and hydraulic transients can damage pumps and interrupt supply.
Gate valves provide low-loss isolation while non-slam check valves protect pump discharge lines.

Full-bore pipeline isolation for raw-water mains and pumping stations.
Controlled closure helps reduce reverse flow and damaging hydraulic surge.
Quarter-turn tight shutoff for bypass, drain and auxiliary water lines.
WATER TREATMENT
Control each stage of the treatment process.
Treatment plants depend on repeatable flow control through coagulation, filtration, disinfection and clean-water storage.
- Coagulation and flocculation
- Filter isolation
- Backwash air and water
- Clearwell inlet and outlet
High cycling frequency, chemical exposure and limited shutdown windows demand reliable seats and simple maintenance.
Gate, ball and globe valves are matched to chemical compatibility and the operating sequence.

Dependable throttling and shutoff for treatment and dosing pipelines.
Compact flow switching for treatment trains, backwash and bypass service.
Automatic reverse-flow protection for pumps and process equipment.
TRANSMISSION & DISTRIBUTION
Isolate networks without compromising flow.
Transmission mains, reservoirs and pressure zones require valves that remain operable after long static periods and minimize energy loss.
- Transmission mains
- Reservoir isolation
- Booster stations
- Pressure control zones
Large diameters, high flow velocity and infrequent operation increase torque and surge risk.
Low-torque isolation valves and check valves support network sectionalizing and booster pump protection.

Welded-body isolation designed for buried transmission pipelines.
Full-bore API 6D isolation for high-capacity pipeline service.
Adjustable closing response for high-flow pump discharge service.
WASTEWATER & SLUDGE
Handle solids without clogging the line.
Collection and treatment systems must isolate sewage, grit, screenings and concentrated sludge under difficult maintenance conditions.
- Lift stations
- Screening and grit removal
- Aeration systems
- Sludge transfer and dewatering
Fibrous material, abrasive solids and sediment can block conventional valve cavities and damage sealing surfaces.
Full-port gate and ball valve designs reduce internal restrictions in solids-bearing service.
