Oil & Gas Industry:
Upstream, Midstream & Downstream Solutions

Shield supplies API‑certified valves for the entire oil and gas value chain – from wellhead extraction to pipeline transport, refining, and petrochemical processing. Our high‑pressure, sour service, fire‑safe, and cryogenic valves ensure safety and reliability in the most demanding operations.

API 6D / 607         Fire‑Safe         NACE MR0175         Cryogenic        Up to 2500# Class

Upstream – Wellhead & Production

Rugged gate valves, ball valves, and check valves for Christmas trees, manifolds, injection systems, and subsurface safety. Materials resist H₂S, sand, and high pressures.

Midstream – Pipelines & Terminals

Full‑port ball valves, through‑conduit gate valves, and check valves for mainline block, pump stations, storage terminals, and custody transfer. Designed for long‑term reliability.

Downstream – Refining & Petrochemical

Forged steel gate, globe, and check valves for high‑temperature/high‑pressure processes. Fire‑safe ball valves and severe service control valves for FCCUs, hydrocrackers, and chemical units.

Upstream – Extraction & Production

• Wellhead & Christmas Tree Valves: Master isolation, wing, and swab valves – engineered for high pressure and sour service.

• Production Manifolds: Valves for flow distribution and diversion, enabling controlled gathering from multiple wells.

• Injection Systems: Globe and check valves for water, gas, or chemical injection in enhanced oil recovery (EOR).

• Materials: Carbon steel, alloy steel, stainless steel with special trims to resist erosion, corrosion, and H₂S.

Midstream – Pipeline Integrity

• Mainline Block Valves: Full‑port pipeline ball valves & through‑conduit gate valves for reliable isolation and emergency shutdown.

• Pump & Compressor Stations: Check valves prevent backflow; ball and gate valves for station isolation.

• Storage & Tank Farms: Butterfly and ball valves for loading/unloading crude and refined products.

• Custody Transfer: Precision‑engineered ball valves for metering stations with exceptional sealing integrity.

• Protective Features: Anti‑blowout stems, cavity pressure relief, fusion‑bonded epoxy coatings for buried or above‑ground service.

Downstream – Refining & Severe Service

• High‑Temperature / High‑Pressure: Forged steel gate, globe, and check valves for furnace inlets/outlets, reactor feeds, and heat exchanger lines.

• Severe Service & Control: Advanced control valves and severe service ball valves for FCCUs, hydrocrackers, and critical flow loops.

• Fire‑Safe Valves: API 607/6FA ball valves and butterfly valves designed to maintain a seal in fire conditions.

• Corrosive & Abrasive Service: Duplex stainless steels, exotic alloys, and specialized linings for catalysts, acids, and caustics.

LNG & Cryogenic Transport

• Cryogenic Ball & Gate Valves: Extended bonnets, stainless steel 316L construction, designed for ultra‑low temperatures.

• LNG Loading/Unloading Arms: Quick‑operation, leak‑tight valves for flammable liquefied gas.

• Storage & Vaporization: Valves for LNG storage tanks, send‑out lines, and vaporizers – reliable in static and dynamic cryogenic conditions.
