Water Treatment
Stainless Steel Valves for Water, Wastewater and Pump Stations
The Role of Valves in Water Treatment
Water and wastewater systems run on reliable isolation and flow control. Stainless steel ball valves handle the corrosive, chemical-dosed and continuously cycling conditions of treatment plants, pump stations and distribution lines. Their corrosion resistance and easy automation make them a long-life choice from raw water intake to final discharge.
Whether the job is a municipal plant or an industrial water loop, stainless valves keep water, chemicals and effluent under accurate control.
Selecting Valves for Water Service
Water and wastewater service brings its own demands: chlorinated water, dosing chemicals, grit and round-the-clock cycling. Selection usually comes down to:
- Corrosion resistance: CF8M (316) resists chlorides and treatment chemicals better than 304.
- Chemical-ready seats: PTFE seats handle dosing chemicals and give bubble-tight shut-off.
- Flow efficiency: full-bore ball valves reduce pressure loss on large lines.
- Easy automation: ISO 5211 mounting for pneumatic or electric actuators on automated plants.
Materials are typically CF8 (304) or CF8M (316) stainless steel with PTFE seats, selected to match the medium and temperature.
Manufacturing and Quality Standards
Every valve is built and tested to a consistent standard before it ships:
- Tight shut-off testing: each valve is pressure-tested for bubble-tight shut-off before shipment.
- Automation-ready: ISO 5211 mounting and NAMUR interface for pneumatic or electric actuators.
- Control integration: limit switches and solenoids for connection to PLC or SCADA systems.
- Material traceability: documented stainless steel grades for each batch.
- Quality system: built under an ISO 9001 quality management system, CE marked.
Key Applications of Valves in Water Treatment
- Raw water intake and screening
- Pump station isolation
- Chemical dosing and coagulant feed
- Filtration and backwash lines
- Disinfection dosing (chlorine or ozone)
- Clarifier and sludge lines
- Distribution and booster stations
- Wastewater and effluent control
