Swing Check Valves

A reliable source for Check Valve information and leading Check Valve Companies & Manufacturers.

A swing check valve is a type of check valve that employs a swinging disk on a hinge to regulate the flow of a liquid, gas or solid stream in a single direction, while keeping backflow from contaminating the source fluid. In other words, the swing valve, like all check valves, is a non return valve. Read More…

The swing check valve system, like all other check valve systems, depends on gravity and reverse flow for operation and therefore does not require any other products to get the job done. This is partly why all check valves are in high demand. The basic mechanics of valve systems are the same with swing check valves, which are also known as the tilting disc check valves, as they are with ball check valves and other plug varieties.

The difference in the process lies with the plug that swings on a hinge when a certain amount of pressure, which is going in the appropriate direction, is placed on it. The ball valve uses a spherical ball to achieve the flow pressurization, while the lift check valve uses a sliding rod to move its disk back and forth across the opening.

Most large check valves are swing check valves, an everyday example being the valve that rises and falls to flush a toilet. The manual turning of the handle is a common theme among swing valves, which usually involve some sort of physical motion to activate them. However, in some internal pipe systems, a spring check valve is combined with the swing valve so that no human interaction is necessary.

A swing check valve may be made of a number of different materials, depending on the pressure to be sustained and the type of liquid or gas that passes through it. Common materials used to construct a swing check valve include steel, brass and polyvinyl chloride (PVC). Like most check valves, there is a vast variety of commercial, domestic and industrial industries that put swing valves to use.

Pharmaceutical, sewage, water treatment, food and beverage processing, chemical processing, medical, power generation, pharmaceutical, chromatography, agriculture, hydropower and petrochemical companies are all included on the list of industries. When a mechanism can prevent product malfunction with limited human involvement, it is a desirable mechanism. However, part of the check valve success is due to laws requiring it for the safety of gas, pressure and water applications.
