The Industry

API Compliance, Field-Proven Reliability

Oil & gas valves operate in some of the most regulated, codified, and unforgiving service in industry — pipeline isolation valves rated for ANSI Class 1500+, fire-safe ball valves at refinery process units, cryogenic LNG service at -260°F, and the steam injection systems that drive heavy oil production.

For three decades, Miller Valve & Controls has supplied upstream, midstream, and downstream operators with API-compliant valves engineered to the codes, the certifications, and the field reliability that hydrocarbon service demands. From wellsite to refinery, gas plant to LNG terminal, our manufacturer partners deliver the right valve for the right application.

We work with operators, EPC contractors, and pipeline companies to spec valves that meet the codes (API 6D, API 607, API 6FA, ISO 15848, NACE MR0175) and deliver the cycle life that production schedules require.

Common Applications

Where Our Valves Earn Their Keep

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

Brine & Produced Water

Severe-service knife gates and ball valves for brine produced water, salt water disposal, and recovery service. Corrosion-resistant for high-chloride streams.

Steam Service

Metal-seated ball valves for steam injection in heavy oil production, SAGD, and steamflood operations. Designed for thermal and pressure cycling.

LNG Service

Cryogenic ball, gate, and globe valves for LNG plants, regas terminals, and small-scale LNG facilities. Engineered to MSS-SP-134 and API 6D.

Pipeline Isolation

API 6D-certified ball and gate valves for transmission pipelines, gathering systems, and station isolation. Fire-safe, fugitive emissions, full traceability.

Refining Service

API 607 fire-safe ball valves for refinery process units. Materials and trim selection for everything from light hydrocarbons to heavy resids.

Wellhead & Christmas Tree

High-pressure forged-body valves for wellhead, choke, and surface production equipment. Built for upstream pressures and conditions.

Gas Processing

Cryogenic and ambient-temperature valves for gas plants, fractionators, and cryogenic recovery units. Materials matched to the streams.

Tank & Terminal Service

Storage tank isolation, loading rack, and terminal manifold valves. Reliable shutoff for the high-volume movements that terminal operations require.

Vendor Partners

Trusted Manufacturers for Oil & Gas

Our oil & gas valve solutions draw from a curated set of manufacturer partnerships — chosen for their API compliance, field reliability, and the cycle life that hydrocarbon service demands.
