Check Valves

A dual plate check valve is a type of non-return valve that allows fluid to flow in only one direction and prevents backflow. It consists of two spring-loaded, semi-circular plates that pivot on a central hinge pin. When forward flow occurs, the plates open to allow passage with minimal resistance. If flow reverses, the plates quickly close to stop backflow and protect the system. Their compact size, efficient flow, and reduced risk of water hammer make them ideal for applications in water treatment, oil and gas, and chemical processing. 

A Dual Plate Check Valve (DPCV) is a compact, non-return valve with two spring-loaded, semicircular plates that pivot on a central hinge to prevent backflow, offering superior performance with less weight and smaller size than traditional swing checks. It minimizes water hammer and pressure drop due to its quick, low-inertia closing action, making it ideal for pipelines, water systems, oil & gas, and HVAC, providing efficient flow control in a lightweight, space-saving design. 

A swing check valve is a mechanical valve designed to allow fluid flow in only one direction, automatically preventing backflow. It features a hinged disc that swings open when fluid is flowing forward and closes when the flow stops or reverses, protecting systems from damage and maintaining integrity. These valves are used in a wide range of industries, including water supply, chemical processing, and HVAC systems, and they offer low pressure drop and full flow capacity.
