Product detail
| Product code | Alfa Laval Unique Sampling Valve - Single Seat |
| Applications | Hygienic processes including food and beverage, personal care and biopharm |
Aseptic and sterilizable solution for safe sample collection
- Design ensures hygienic and contamination-free sampling
- Easy to operate thanks to simple working principle
- Highly reliable operation (rated to 10 bar) and three year warranty for all non-wearing parts
- Safe sampling through features such as non-return, quick couplings, pressure relief valve for steam and more
- Enhanced cleanability - valve body made of single piece of stainless steel provides smooth, crevice-free surfaces eliminating bacterial build-up risk
Standard design
The valve consists of three parts, a valve body, an actuator and a membrane seal. The rubber membrane seal is placed on the stem of the actuator and works as a stretchable plug.
The valve bodies and actuators are interchangeable. The single seat valve can be upgraded to a double seat valve by replacing the handle or actuator with an upgrade kit - see ordering leaflet for accessories.

Unique single-seat sampling valves
Designed for standard hygienic sampling, the single-seat sampling valve has two positions: open and shut. It can easily be upgraded to a double-seat valve by replacing the handle or actuator with an upgrade kit.
Unique double-seat sampling valves
The specially engineered Unique double seat sampling valves are an excellent choice for applications that require higher cleanability. Its patented double seat technology ensures higher cleanability and sterilization of the valve seat and pipe connections. Designed for truly sterile sampling, the double-seat sampling valve has three positions: open, shut and sterilization.
