When you’re dealing with seawater, corrosion is not just a concern — it’s the enemy. Desalination plants run 24/7, pushing high-salinity fluids through filtration and pressure systems that can wear down equipment fast. That’s where Phoenix ValSteer valves come in.
We engineer valves that stand up to brine, scaling, and continuous operation. Whether it’s high-pressure intake, chemical dosing, or backwash lines, we deliver valves that keep desalination systems running smoothly and safely.
The Role of Valves in Desalination Plants
Challenges Faced in Desalination Valve Applications
- Corrosive media with high chloride content
- Scaling from minerals and salts
- Continuous operation with minimal shutdown tolerance
- Compatibility with chemical dosing (chlorine, antiscalants, etc.)
- High-pressure operation in reverse osmosis systems
- Need for tight shut-off and reliable sealing
Where Our Valves Are Used in Desalination Plants
Phoenix ValSteer valves are deployed across all key zones of desalination plants:
- Seawater intake lines : Duplex and super duplex gate valves to resist chloride corrosion
- Pre-treatment and filtration : Knife gate valves to handle sand, silt, and debris
- High-pressure pumps and RO systems : Class 600 globe and ball valves for isolation and throttling
- Chemical dosing lines : SS316 and PTFE-lined valves compatible with corrosive chemicals
- Backwash and brine reject systems : Swing check valves to manage reverse flow
Recommended Valve Types and Pressure Classes
Valve Type | Pressure Class Range | Common Materials | Typical Application |
Gate Valve | Class 150 to 600 | CF8M, Duplex, Super Duplex | Seawater intake and brine reject lines |
Ball Valve | Class 150 to 600 | CF8M, Super Duplex | High-pressure isolation in RO systems |
Globe Valve | Class 150 to 600 | SS316, CF8M | Throttling in RO and chemical dosing loops |
Check Valve | Class 150 to 600 | Super Duplex, CF8M | Preventing reverse flow in pump discharge and reject streams |
Knife Gate Valve | Class 150 to 300 | SS316, Duplex | Sand and silt handling during filtration |
Material Selection for Desalination Valve Applications
We select materials based on their proven resistance to saltwater, scaling, and chemical attack:
- Super Duplex (UNS S32750, S32760) : Exceptional for chloride resistance and seawater handling
- Duplex Steel (UNS S31803) : High strength and corrosion resistance for general plant use
- Stainless Steel (SS316, CF8M) : Standard for brine and chemical dosing
- PTFE-lined options : For aggressive chemical lines
- All materials are tested for corrosion resistance and available with NACE MR0175 certification if required
