Sampling Valves

Since 1974 FAMAT has developed and manufactured a complete range of “Dead Zone Free” Sampling Valves, based on the patented EPT concept : Expanding Piston Technology.

Almost all FAMAT Valves are based on our patented EPT: Expanding Piston Technology.

The patented system inside this piston allows the PTFE external coat to expand and insure a perfect tightness from vacuum up to Full rating pressure 10 bar (145 psi).

The advantage of having an expandable piston inside the valve is to eliminate the need for O-rings that can be damaged during valve operation, and consequently generate contamination for production.

Another big advantage of our design is that in closed position, the piston will be flush with the connection point, leaving no dead space.
