Socket Check Valve

The RK104 brass socket check valve is not only extremely cost-effective; it is also highly versatile for use with a wide range of media. The key advantage of a check valve over a non-return valve is that, unlike a poppet valve, the disc is not positioned fully in the flow of the medium. This allows pressure losses to be kept to a minimum. In addition, a check valve can also be used without issues with slightly contaminated media. Further specifications for the RK104 can be found in the right-hand column. We offer a wide range of non-return valves. Our sales team will be happy to advise you in finding the right non-return valve for your application.
