Since 1974, FAMAT has been a trusted partner for industries that demand precise, hygienic, and contamination-free sampling. Our full range of sampling valves is engineered for aseptic and sanitary processing, using our patented EPT® (Expanding Piston Technology), a breakthrough design that guarantees zero dead zone, no O-rings, and a perfectly watertight seal under pressure up to 10 bar (145 psi).
With EPT®, the outer PTFE layer of the piston expands outward to ensure complete sealing, eliminating traditional wear points and contamination risks. Whether you need manual, aseptic, membrane, steam-barrier, or pressure sampling, our valves provide safe and repeatable sampling for pharmaceuticals, biotech, food, beverage, and cosmetics, even under the most demanding process conditions.
Robust sampling valves for high-volume applications. Ideal for powders, granules, pastes, and liquids under pressure or vacuum.
Compact and versatile valves for standard process lines. Perfect for pharmaceutical and chemical sampling in smaller systems.
Specialized valves for gas or micro-quantity liquid sampling. Engineered for precision in high-pressure, high-temperature conditions.
FAMAT sampling valves are designed to safely and accurately extract liquid or semi-liquid samples from pipelines, reactors, or tanks, without compromising sterility, product quality, or process pressure.
At the core of our valve design is our patented EPT® (Expanding Piston Technology). When the valve is opened, the PTFE-coated piston retracts, allowing a clean and controlled flow of product for sampling. Once closed, the piston expands outward, creating a perfect vacuum-tight seal, without the need for O-rings or gaskets.
Contact usOur valves are engineered to deliver precise and sterile sampling without risk of cross-contamination. Whether you're handling liquids, semi-solids, or powders, each sample is representative and repeatable, even under challenging pressure or temperature conditions.
The internal geometry eliminates product retention areas, making the valves fully clean-in-place (CIP) and sterilize-in-place (SIP) compatible. This ensures effortless maintenance and consistent hygiene, batch after batch.
From manual to pneumatic actuation, our valves support multiple sampling methods — including pressure, membrane-sealed, steam-barrier, and powder sampling. Flexible integration with accessories like sampling bottles, pressure relief devices, or sterile connectors ensures adaptability across all process types.
Built from high-grade stainless steel and engineered to withstand full vacuum to 10 bar pressure and temperatures up to 300°C, FAMAT valves offer long service life and safe performance in the most demanding environments.
With over 50 years of engineering experience, FAMAT delivers sampling solutions trusted by pharmaceutical, biotech, food, and cosmetics manufacturers around the world. We combine innovation, reliability, and precision, every valve, every time.
Our patented Expanding Piston Technology (EPT®) is a globally recognized innovation that enables safe, sterile, and highly accurate sampling, with zero risk of cross-contamination.
Piston expands against the valve walls – ensuring a perfect seal and eliminating product retention.
No O-rings or sealing seats – removing common contamination risks and simplifying maintenance.
