The Industry

Built for Saltwater Realities

Marine and dredging applications face a punishing combination of conditions — seawater corrosion, abrasive sediment loads, vibration from heavy equipment, and the around-the-clock service that ships, dredges, and offshore platforms demand. Standard valves built for fresh-water industrial duty don't survive — period.

For three decades, Miller Valve & Controls has supplied marine and dredging customers with valves engineered for saltwater environments. Super-duplex stainless, nickel-aluminum bronze (NAB), titanium, and the specialty coatings that survive years of seawater exposure. We've supplied dredge operations, naval shipyards, desalination plants, and offshore service vessels.

We work with marine engineers, dredging contractors, and naval programs to spec valves that hold up to the abuse and meet the certification requirements that marine service demands.

Common Applications

Where Our Valves Earn Their Keep

Every marine system has its own challenges. Here's how we approach the most common — and the valve types we recommend for each.

Seawater Service

Super-duplex, NAB, and titanium ball, butterfly, and check valves for seawater intake, discharge, and circulating systems.

Desalination

Reverse osmosis, MSF, and MED plant valves. Specialty alloys for the brine and concentrate streams that defeat standard stainless.

Dredging Systems

Abrasion-resistant knife gates and ball valves for dredge slurry, suction lines, and discharge piping. Built to handle high-velocity sediment loads.

Ballast & Bilge

Marine-grade isolation and control valves for ballast water management, bilge pumping, and tank-cleaning systems.

Fuel & Lube Oil

Bunker fuel, marine diesel, and lube oil valves. Fire-safe and compliant with classification society requirements.

Firewater Systems

Marine firewater isolation and deluge service. Materials and certifications matched to ABS, USCG, and Lloyd's standards.

Cooling Systems

Engine cooling, HVAC, and auxiliary cooling water service. Reliable isolation in saltwater and fresh-water service alike.

Naval & Defense

Specialty valves for naval platforms — propulsion, weapons, and auxiliary systems. Compliance with MIL-spec and program-specific requirements.
