Single seat sampling valves with a variety of options to suit various medias
Alfa Laval Unique Sampling Valve make it possible to obtain representative samples of food and beverage, personal care and biopharm products. These reliable single- and double-seat valves contribute to quality, and cost-effective sampling.
Concept
The Unique Sampling Valve is a single seat valve designed for sterilisation before and after each sample. The valve body and connecting pieces are made from one piece of material to avoid cracks and welding pores.
Working principle
Sterilising: when the valve is closed, the channel between the valve ports is open for sterilisation. If using steam, a small pressure relief valve (optional) on the outlet is recommended. Sampling: when the valve is opened, the stem and the membrane seal are retracted, allowing liquid to pass.
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.
