Dual Plate Check Valve Manufacturer in USA

SVR Global is a trusted dual plate check valve manufacturer in USA delivering high-performance valves designed to meet the rigorous demands of modern industries. Our dual plate check valves, also referred to as wafer check valves, are widely used across oil & gas, petrochemicals, water treatment, power generation, and marine sectors. As one of the leading valve manufacturers in USA, we provide API, ASME, and ISO-certified valves that ensure durability, efficiency, and long service life for critical applications.

What is a Dual Plate Check Valve ?

Dual plate check valves are essential components in industrial piping systems. They are designed to prevent reverse flow and protect pumps, compressors, and other equipment from potential damage. The dual plate design consists of two spring-loaded plates mounted on a hinge pin. These plates swing open with forward flow and close quickly when the flow reverses, ensuring reliable backflow prevention while minimizing water hammer. This makes them superior to traditional swing check valves in terms of energy efficiency, compactness, and response speed.

Advantages of Dual Plate Check Valves
• Compact design and lighter weight compared to conventional swing check valves
• Energy-efficient operation due to reduced pressure drop across the valve
• Quick closure mechanism reduces the risk of water hammer and pipeline stress
• Suitable for both horizontal and vertical installations, providing flexibility in design
• Low maintenance requirements and long service life for cost savings
• Easy installation between flanges without requiring additional pipe supports
• Available in a variety of materials including carbon steel, stainless steel, duplex, and exotic alloys for corrosive or high-temperature environments

Types of Dual Plate Check Valves Manufactured by SVR Global
• Wafer type dual plate check valve – Designed for compact pipelines where space is limited and weight reduction is critical
• Lug type dual plate check valve – Features threaded lugs for secure alignment and allows dead-end service in certain conditions
• Flanged dual plate check valve – Built for heavy-duty applications requiring robust sealing and easy maintenance
• High-performance dual plate check valve – Engineered to handle high-pressure and high-temperature environments found in oil & gas and power industries

Key Parts of a Dual Plate Check Valve
• Valve body constructed from ductile iron, carbon steel, stainless steel, or duplex stainless steel
• Two spring-loaded plates or discs that open and close with flow changes
• Hinge pin that supports the plates and ensures smooth operation
• Torsion springs that provide rapid closure to prevent backflow
• Seat ring for tight sealing against reverse flow
• Gasket or sealing element for leak-proof installation between pipeline flanges

Industries Using Dual Plate Check Valves in USA
• Oil & gas industry – Dual plate check valves are widely installed in upstream, midstream, and downstream operations to prevent reverse flow in crude oil, natural gas, and LNG pipelines
• Petrochemical and refinery plants – Used in chemical processing units, refineries, and hazardous fluid transport systems where reliability is essential
• Power generation plants – Applied in steam lines, boiler feedwater systems, and cooling water circulation loops to protect turbines and pumps
• Water and wastewater treatment facilities – Ensure reliable backflow prevention in pumping stations, desalination plants, and municipal water distribution systems
• Marine and offshore industries – Provide corrosion-resistant performance for seawater, ballast water, and offshore drilling operations
• Industrial manufacturing – Applied in general process industries such as pulp and paper, food processing, and pharmaceuticals where flow protection is necessary
