Water treatment, desalination and power generation each use the same valve families for very different reasons. This section explains where valves sit in the flow scheme, which type suits which duty, and what the buying specification usually demands.
Request a Quote →A valve is chosen to survive a specific medium, a specific duty cycle and a specific approval regime. Two valves can share a size, a pressure class and a face-to-face dimension and still be different products, because one is coated for potable water and the other built from a corrosion-resistant alloy for seawater. Application first keeps the medium, the actuation requirement and the documentation package in the same conversation as the price.
This section is organised by industry rather than by product family. The product pages describe what we build; these pages describe how those products are applied.
Municipal and industrial plants. Intake, filtration, chemical dosing and sludge handling, with the material split between potable and non-potable service.
Seawater reverse osmosis and thermal desalination. Chloride-resistant wetted parts and the corrosion allowances seawater forces onto every material choice.
Thermal, combined-cycle and biomass plants. Cooling water, condensate, feedwater and steam circuits, where temperature and cycling decide the valve.
Mineral processing, tailings and slurry transport. Abrasion resistance decides service life, and it drives the choice between knife gate, metal-seated and lined designs.
Chilled water, condenser water and data-centre cooling loops, where isolation quality and low pressure drop matter more than pressure class.
Upstream, midstream pipeline and refining duty. Fire-safe design, material traceability and the documentation package pipeline projects expect.
Chemical, food and beverage, pulp and paper and marine duties are covered through our product pages and the standards notes in the blog. See Markets We Serve for how projects in each region are handled.
| Industry | Deciding Factor | Usually Specified |
|---|---|---|
| Water treatment | Potable-water contact and solids in the stream | AWWA C504, AWWA C509/C515, NSF/ANSI 61 on request |
| Desalination | Chloride corrosion and continuous cycling | Duplex or super duplex wetted parts, API 609, ISO 5208 |
| Power generation | Steam temperature and thermal cycling | ASME B16.34, API 600, API 598, ASTM material grades |
| Oil & gas | Fire exposure and emission control | API 6D, API 607, API 6FA, anti-static design |
| Chemical | Media compatibility and permeation | PTFE or PFA lining, ASME B16.34, NACE MR0175 where sour |
| Food & pharmaceutical | Hygiene and cleanability | FDA-compliant elastomers, 3-A style finish, CIP-compatible seats |
Standards are listed as typical project requirements. Reguvale holds ISO 9001 quality-system certification and SGS-CSTC factory audit reports; other approvals are available on request for qualified orders and are confirmed in writing at quotation stage.
Across industries the paperwork converges on the same core set: a mill test certificate to EN 10204 3.1 traceable to the heat number, hydrostatic and seat test reports to API 598 or ISO 5208, and dimensional inspection records against the drawing. Sector additions include material certification for potable-water contact, non-destructive examination reports, third-party inspection release notes and, on oil and gas work, fire-test documentation.
Deciding the documentation package at enquiry stage is cheaper than discovering it at inspection. Tell us which certificates the project requires and we will confirm what can be supplied before you place the order.
Because the medium, the duty cycle and the approval regime drive everything else. A DN300 valve on a potable water main, on a seawater reverse osmosis feed line and on a boiler feedwater line looks similar on a drawing but differs in body material, seat elastomer, coating and test documentation.
Water and wastewater treatment, desalination, power generation, oil and gas, chemical and petrochemical processing, mining and slurry handling, food and beverage, pulp and paper, HVAC and building services, and marine. Each has its own standard set and documentation expectations.
The tests are broadly the same but the paperwork differs. Most projects ask for a mill test certificate to EN 10204 3.1 and hydrostatic and seat test reports to API 598 or ISO 5208. Water projects add material certification for potable water contact, and power and oil and gas projects often add third-party inspection.
Yes. A rubber-seated butterfly valve is used in water treatment, cooling water circuits and desalination pretreatment. What changes between industries is the body material, the seat elastomer, the coating and the documentation package, not the basic design.
Send the line list or a valve data sheet: size, pressure rating, medium, temperature, connection standard, actuation requirement and the approval regime the project specifies. We then quote the valve and the documentation package together.
