Shutter valves

Alfa Laval shutter valves are hygienic three-way valves that divert the flow of products that are highly viscous, contain large particles, or have strict requirements on minimizing pressure loss. Compact, reliable and pressure-shock resistant, these valves can be operated in manual or automatic (pneumatic) mode. They are engineered for use across the food, chemical, pharmaceutical and other industries with high requirements for process and product hygiene.

Simple, straightforward inline three-way valves that easily divert fluids that are highly viscous, contain particles, or require minimal pressure loss

  • Low flow restriction enables viscous liquids and liquid containing particles to flow easily through the valves
  • Simple, straightforward and hygienic design easily integrates into various pipelines and systems
  • Long-lasting, easy operation and maintenance due to few quality components and moving parts
  • Easy, three-way routing of products when used with either manual handles or flexible, easy-to-select pneumatic actuators
  • Compact, convenient, space-saving three-way valves

Get more uptime using Alfa Laval shutter valves to route your viscous liquids and liquids containing particles with minimal pressure losses – easily and conveniently.

Engineered for ease of routing, high hygiene, low maintenance and safe operation, these valves meet the demands of easy passage of fluids through the hygienic processing systems as well as easy, convenient and thorough Cleaning-in-Place.


How does shutter valves work?

Alfa Laval shutter valves consist of rigid bodies with an internal cylindrical bore, a PTFE shutter and three ports for pipe connection. The two lids have guide rings for an internal shaft, which supports and positions the shutter.

The valves are operated either manually by means of stainless-steel handles or automatically by means of compressed air using pneumatic actuators. A spring system presses the shutter against the inside cylindrical surface of the valve body thereby ensuring complete tightness.

Manually operated valves can be fitted with indication units installed laterally. The valve actuator is available in two versions: a single-acting actuator or a double-acting actuator. The actuator consists of a system of cylinders and one or two main pistons interconnected with a toothed bar, which interacts with a gear wheel on the valve shaft.

The pneumatic actuator of automated valves can be fitted with an Alfa Laval ThinkTop® V50 or V70 control unit, or an Alfa Laval indication unit installed laterally for remote indication of the valve position.
