Minivalve takes a close look at new materials all the time, assuring best performance against lowest cost. Our valve components are made in Silicone, EPDM, Fluorosilicone, Fluoroelastomer and Perfluorelastomer and other exotic elastomeric materials. If you have a preference for a non-standard material, perhaps one that meets a specific material specification we invite you to let us know. Often we have ready solutions or we find one for you.

Medical Devices

For valves that are used in medical device and pharmaceutical applications we have silicone materials (VMQ) that are certified to pass USP class VI and ISO 10993 biocompetability tests. They are also suitable for Gamma, E-beam, ETO and Steam sterilization.

Food and Water

Certain of our standard materials are certified to pass international food and potable water requirements such as FDA, NSF, Bfr,


Applications in automotive fuel including fuel alcohol and other fuel mixtures or in engine oil or automatic transmission oil often use fluorosilicone (FVMQ) and fluoroelastomer(FKM) rubber. Our materials do meet several automobile manufacturers material specifications.


For general purpose valve applications we often recommend silicone rubber (VMQ)
As far as the resistance of elastomeric materials against chemicals is concerned we refer to the table below. Attacked in this respect may not necessarily mean that the material is not suitable in your application. Our part designs often tolerate a certain amount of swell. Contact us in case of doubt.

High and low Temperature

Generally speaking, silicone, fluorosilicone, fluoroelasotmer and perfluoroelastomer can all serve high temperatures up to 200
