Unique Sampling Valve – Double Seat

Double 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 specially designed for the food, pharmaceutical and biotechnological industries. The valve is equipped with a double seat which makes it possible to sterilise the entire seat between sampling, thereby eliminating the risk of cross contamination.
 

Working principle

The patented double seat ensures representative sampling as the seat area is accessible for sterilisation. The inner spindle pushes the membrane seal down onto the inner seat, closing off the product.
Once the inner spindle is in place, the outer spindle is retracted, moving the membrane seal away from the outer seat making it possible to remove any remaining product and sterilise the outer seat.
 

Standard design

The Unique Sampling 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.
