Dual Disc Check Valves

Dual disc check valves are a popular alternative to the original check valve for a number of reasons. With a design that promotes fast closing to increase performance, dual plate check valves are also a great space and cost saving alternative. They are easier to install and operate and the components also feature a longer service life.

As well as the benefits listed above, a double plate check valve features disc stabilisation and spring assisted closing, delivering benefits such as reduced disc wear and non-slam performance. The innovative design of the double disc check valve also prevents any process fluid from returning upstream, maximising performance and increasing service life.

Dual disc check valves are ideal for most applications, including: Potable Water, Raw Water, Wastewater Treatment, Sea water, Irrigation, Abrasive Slurries, Corrosive Chemicals, Desalinations, Fire Protection, Mining and Industrial Applications.

From leading manufacturers, Val-Matic, the dual disc check valves are designed to be compact and light weight, increasing versatility in a wide range of applications. Featuring a synthetic seat, the double plate check valve offers a bubble-tight shut off and body alignment fins, increasing the efficiency of the component and allowing precise alignment in certain installations. Thanks to the simple design of the dual plate check valve, they are also available in a wide range of sizes, from 2” up to 60”.

The double plate check valve from Val-Matic can be used in a wide range of applications, however the basic installation requires users to fit the valve body, with the flow arrow pointing in the direction of flow when the system is in operation.

It is important to bear in mind that dual plate check valves being used in air service will require special springs to allow full valve opening.
