Dual plate check valves are the unsung heroes of flow control, preventing backflow that wrecks equipment and uptime. If you’re engineering, buying, or maintaining systems, understanding these valves helps you spec smarter and avoid headaches. Here’s where they shine, why they’re efficient, and why Concorde Valves & Automations builds them to behave in the field.
Dual plate check valves protect lines in oil refineries, chemical plants, and utilities by stopping reverse flow. Two spring-loaded plates close automatically when flow stops, giving reliable shutoff with minimal fuss. The compact form factor makes them easy to fit even when space is a rumor.
They help maintain system integrity, cut downtime, and keep maintenance sane. If performance and lifecycle cost matter, you want quality here.
Below we cover advantages and where dual plate designs beat the usual suspects.
Valve Type | Dual Plate Check Valve |

Plate Design | Two spring-loaded plates |
Pressure Class | PN16, PN25, PN40, ANSI Class 150, 300 |
Size Range | 2 inches to 48 inches |
End Connection | Flanged, Wafer, Lug |
Temperature Range | -20°C to 200°C (varies with material) |
Sealing Material | EPDM, NBR, Viton, PTFE |
Operation | Automatic, non-slam design |
Certification & Standards | API 594, ASME B16.34, EN 558 |
Applications | Oil & Gas, Water Treatment, Chemical Processing, HVAC, Power Plants |
This table covers core specs so you can map material, pressure class, and sealing to the actual duty conditions, not wishful thinking.
Lower pressure drop than swing types, so you keep energy use and turbulence in check. That’s money saved and performance sustained.
Compact footprint makes installs easier in tight racks and retrofits. Less steel, less weight, less swearing during commissioning.
Lighter than swing designs, which helps with handling, installation, and shipping. The bean counters will notice.
Dual plate wins on pressure drop and sealing reliability thanks to the spring-loaded mechanism. Swing check needs more space, adds turbulence, and drops more pressure. If space and efficiency matter, dual plate is the grown-up choice.
At Concorde Valves & Automations, precision machining, controlled heat treatment, and 100% testing against standards produce valves that behave predictably under load. Materials and coatings are selected for service, not marketing poetry.
From hydrocarbons to chilled water, dual plate check valves keep flow going the correct way. Pipelines, filtration and distribution, chemical dosing, HVAC loops — if reverse flow is a risk, this is your seatbelt.
Price depends on size, material, and pressure class. The lighter build vs swing check cuts shipping and install costs too. Ask for a current price list if you enjoy spreadsheets.
Buy cheap, fix often. Or buy once. Concorde Valves & Automations builds to API/ASME/EN, tests every unit, and supports it after the invoice. That’s how you keep unplanned downtime hypothetical.
