Check valve


In addition to ball valve, Magival Valves manufactures check valves. This type of valve allows only one direction of flow. Our valves production in Italy is totally internal and divided into two specialized locations for the production of ball valve. The Besnate site is used for production, with a large fleet of machines; the Casorate Sempione site is used for valve assembly, testing, and the sandblasting and painting service.
Magival Valves follows and supports the customer from the beginning to the end of the project. The selection of the raw material is made according to the customer’s specifications or according to Magival standards; even painting and marking can be done according to customer specifications.

The valves production in Italy is continuously improved and renewed with the continuous adoption of the most modern construction technologies to guarantee a high quality standard of our product.


Check valves consist of a central element, which can be a disc made of different materials, which is pushed through the force of a spring against the valve base.
The installation of this type of product is ideal for systems that have flow circulation in one direction only, thus preventing the occurrence of reflux. Our production of check valves has a nominal diameter ranging from ¼ to 2 inches and the pressure class ranges from 800 to 6000 PSI. The ends can be SW according to ASME B16.11, or GAS according to ASME B1.20.1.

The degreasing of these valves is a service that Magival Valves offers for use on systems whose flow is oxygen.
The main feature of these certified valves is the prevention of emptying of the system on which they are installed in the event of a flow stop.
The materials used for the production of ball valve are stainless steel and carbon steel.
The check valves of Magival Valves are certified valves according to the ISO and PED directives.
