|---|---|---|---|
| Municipal Water Transmission | Pipeline isolation | Resilient seated gate valve • Double-flanged butterfly valve | DN/NPS, PN/Class, buried or above-ground installation, protective coating, flange drilling and face-to-face standard |
| Water Treatment Processes | Isolation, backflow prevention and equipment protection | Butterfly valve • Válvula gaveta • Válvula de retenção • Y strainer | Process stage, medium, suspended solids, operating pressure, material compatibility and maintenance access |
| Wastewater Systems | Isolation and backflow prevention in solids-containing service | Resilient seated gate valve • Application-specific butterfly valve • Ball check valve • Swing check valve | Solids content, clogging risk, elastomer compatibility, installation direction and cleaning access |
| HVAC Chilled and Condenser Water | Isolation, automation and equipment protection | Válvula borboleta wafer • Lug butterfly valve • Silent check valve • Y strainer • Rubber expansion joint | Water or glycol concentration, temperature, pressure, insulation clearance, stem position and actuator requirements |
| Pump Suction and Discharge | Equipment isolation and backflow prevention | Válvula gaveta • Double-flanged butterfly valve • Silent check valve • Dual-plate check valve • Swing check valve | Flow rate, operating pressure, pump shutdown characteristics, installation orientation, potential water-hammer conditions and maintenance space |
| Fire Protection Pipelines | Approved isolation and backflow prevention | OS&Y or NRS gate valve • Grooved butterfly valve • Válvula de retenção | Required listing or approval, valve model and size, connection, supervision requirements and project specification |
| Marine Cooling and Ballast Systems | Isolation and backflow prevention | Material-specific butterfly valve • Válvula de retenção • Ball valve | Seawater compatibility, corrosion resistance, body and trim material, protective coating, seat material and marine approval requirements |

Valve Application FAQs
Which valves are commonly used in water treatment plants?
Butterfly valves and gate valves are commonly used for pipeline isolation, while check valves prevent reverse flow. Y strainers can help protect pumps and downstream equipment from debris. Final selection depends on the process stage, medium, pressure and pipeline size.
How do I select a check valve for a pump station?
Consider the flow rate, operating pressure, pump shutdown characteristics, installation space and potential water hammer. Swing, tilting disc, dual plate and silent check valves have different closing characteristics, so the valve should be selected according to the hydraulic conditions.
Which butterfly valve is suitable for chilled water?
Resilient seated wafer or lug butterfly valves are commonly used in chilled-water systems. Selection should consider pressure, temperature, water or glycol concentration, insulation clearance, stem position and manual or actuated operation.
What information is required for valve selection?
Please provide the application, medium, concentration where applicable, DN/NPS, PN/Class, temperature, material, connection, operation method and quantity. Required standards, certifications, destination country and available drawings or datasheets are also helpful.
