29/05/  · The Single Disc Check Valve (Wafer Type Disc Check Valve) consists of four main components: the body, a disc, a star guide and a spring. The Disc check valves are opened by

The most common type of check valve, the swing valve, can be seen in the image below. It is a full port design where the disc is completely out of the way during fluid flow. The directional flow opens the disc. As the flow continues, the disc remains open.

Check valves are also commonly found in waste-water management systems and in manufacturing. For more information, read IHS Engineering360's Valve Applications page.

Lift-type check valves are similarly constructed as globe valves and use a ball or piston, often backed by a spring that opens under a specified pressure but closes as the pressure decreases, thus preventing backflow. These valves are often suited for high-pressure applications. A variant is the stop check valve which doubles as a shut-off valve.

The mechanics of check valve operation are simple and work automatically to stop the fluid from flowing in the wrong direction. Flomatic ® offers many types of check valves for a broad range of configurations, functionality types, sizes and material construction for residential, commercial, process industries and utilities.

Here's a look at these two types of lift check valves: • Piston - This type of check valve is also known as a plug check valve. It operates by controlling the flow of fluid in a piping system by means of the linear motion of a piston within the valve chamber.

Spring Check Valve Types Axial Flow Silent Check Valves. With an axial flow silent check valve, the disc is held in place by a spring that centers the disc to allow smoother flow and immediate opening and closing. The spring and disc are in the center of the pipeline, and the flow passes around the disc. This is unlike the swing valve or other

10/07/  · Swing Check Valves come in a wide range of material types, including PVC, CPVC, Clear and Industrial. There are two types of swing check valves we should look at: • Top-hinged – In this type of swing check valve, the disc is attached to the inner top of the valve with a hinge that allows the disc to open and close.

Parker provides the industry's widest selection of check valves, available in a variety of end connections. Our valves are used in a diverse range of applications, from air and fuel systems to load holding. Our check valves utilize a variety of media including oil, air, and water and are made from materials such as aluminum, stainless steel, brass, and carbon steel.

Types of Check Valves 1. Swing Check Valve 2. Lift Check Valve Lift check valves are significantly custom-made for high-pressure service wherever speed of flow is high. In lift check valves, the piston disc is accurately target-hunting by long contact and an in depth sliding work with the peerless targeted dash pot.
