Controlling liquid is different than controlling a compressed gas.  The liquid valves that we represent are designed to meet the special requirements necessary to provide reliable service and long life under these demanding conditions.  Obviously, when controlling liquid it is necessary that valves have either zero leakage or as close to it as possible.  Another factor is that liquid valves tend to face a much broader range of fluids that they need to survive than do most compressed air applications.  That means that liquid valves have a variety of seal materials such as Buna N nitrile, Fluorpolymer, EPDM, silicone, and others that will be compatible with the fluids you need to control.
To determine what rubber seals to use for a liquid application then we have provided a chemical compatibility chart from Spartan Scientific on our website.  Just follow this link to check it out.
