Maltex Trading is a recognized stockist and supplier of high-quality industrial products, including Dual Plate Check Valves. These valves are crucial components used in a variety of applications, particularly in piping systems where backflow prevention is essential. Below is a technical description for a Dual Plate Check Valve:

• Dual Plate Check Valves are designed to prevent reverse flow in pipelines, ensuring the proper one-way direction of fluid or gas. They automatically close when the flow of media reverses, thus protecting pumps, compressors, and other equipment from damage caused by backflow.

• Dual Plate Construction: Unlike traditional check valves with a single flap, dual plate check valves have two lightweight plates that pivot around a central hinge. This design minimizes the pressure drop, providing better flow characteristics compared to other check valves.
• Compact Design: The dual plate check valve's slim, compact design allows it to fit into smaller spaces and require less installation space.

• Body: Typically made of cast iron, ductile iron, stainless steel, or carbon steel, depending on the application and media to be handled.
• Plates: The plates are usually made of stainless steel or other corrosion-resistant alloys for durability and resistance to wear.
• Seat: The sealing element can be made from elastomers such as rubber, nitrile, or PTFE, ensuring a tight seal and preventing leaks.

• Bidirectional Flow Handling: Dual plate check valves are designed to function in both directions of flow, depending on system requirements.
• Minimal Pressure Drop: The lightweight design of the dual plates minimizes resistance to flow, which results in lower energy consumption and more efficient system operation.
• Ease of Installation: These valves can be installed in horizontal or vertical pipelines, adding flexibility to system designs.
• Corrosion Resistance: The valve construction materials ensure durability and longevity, even in harsh operating conditions.
• Sealing Mechanism: The valve features a spring-loaded mechanism to aid in the sealing process, ensuring the plates close quickly and securely when reverse flow is detected.

• Water and Wastewater Systems: Prevent backflow in water treatment plants and sewage systems.
• Oil & Gas: Used in pipelines, pumping stations, and other parts of the oil and gas industry to protect against backflow.
• Chemical Processing: Used to prevent contamination or backflow of hazardous chemicals.
• HVAC Systems: Prevent reverse flow in heating, ventilation, and air conditioning systems.

• Available in a wide range of sizes, typically from 2 inches to 36 inches or larger, catering to various industrial needs.

• Pressure ratings can range from ANSI Class 150 to Class 2500 and higher, depending on the design.
• Temperature range typically spans from -10°C to 300°C, but special designs can handle higher or lower temperatures.
