Chemical Plant Valve Solutions

Engineered for acids, caustics, chlorine, and hydrocarbons — the process streams where zero-leakage and material compatibility aren't optional.

The Industry

Where Compatibility & Containment Are Non-Negotiable

Chemical processing demands more from valves than almost any other industry. Sulfuric acid, caustic soda, chlorine, hydrofluoric acid, hydrocarbons, and the hundreds of specialty intermediates that flow through a typical plant each demand specific materials of construction, specific seat designs, and specific testing — because the cost of getting it wrong is measured in safety incidents, environmental events, and regulatory consequences.

For three decades, Miller Valve & Controls has supplied chemical plant operators, EPC firms, and engineering contractors with valves engineered to the right material, the right design, and the right testing for each application. From bulk chemical production to fine chemicals, polymers to inorganics, we partner with manufacturers who specialize in the materials and designs chemical service demands.

We work with maintenance teams and project engineers to spec valves that hold up — and to deliver them on the timelines plant turnarounds and capital projects require.

Common Applications

Where Our Valves Earn Their Keep

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

Sulfuric Acid

Specialty alloys and lined valves for H₂SO₄ at every concentration. Acid-resistant ball, plug, and globe valves for production, transfer, and battery service.

Caustic Service

NaOH and KOH valves with stainless, duplex, and nickel-alloy construction. Engineered for the long campaigns and thermal stress of caustic plants.

Chlorine & Hypochlorite

Dry chlorine, wet chlorine, and sodium hypochlorite valves with appropriate materials and oxygen-clean preparation when required.

Hydrocarbons

Ball and butterfly valves for refined products, intermediates, and feedstocks. API 6D, API 607 fire-safe, and fugitive emissions packages available.

Steam Service

Metal-seated ball and globe valves for plant utility steam, process steam injection, and steam-traced systems. Tight shutoff for energy efficiency.

Specialty Reagents

HF, anhydrous ammonia, ethylene oxide, and the hundreds of specialty media that chemical processing demands. Materials matched to media.

Slurries & Solids

Knife gate and pinch valves for crystallization, filtration, and solids handling in chemical processes. Built to handle the abuse.

Process Water & Utilities

Reliable isolation and control for cooling water, demin water, instrument air, and the auxiliary streams that keep production moving.

Vendor Partners

Trusted Manufacturers for Chemical Plants

Our chemical plant valve solutions draw from a curated set of manufacturer partnerships — chosen for their materials science, code compliance, and field-proven performance in chemical service.
