Double seal valves

Alfa Laval double seal valves are cost-effective mixproof valves that safely handle the simultaneous flow of two different products or fluids through the same valve without the risk of cross-contamination. These standardized top-loaded pneumatic valves are ideal for hygienic applications that require additional safety, leakage detection and Cleaning-in-Place (CIP) across the dairy, food, beverage, home-personal care and many other industries.


Safe, reliable and economical mixproof valves for safe separation of two different products in piping systems of hygienic and aseptic processes

  • Safely isolates two process fluids or a process fluid and cleaning media without the risk of contamination
  • Increases both operational and product safety due to self-draining design
  • Produces higher quality products at lower costs using aseptic double seal valves to secure your process
  • More uptime secured through fully maintainable actuator for precision valve control
  • Low maintenance due to few, yet durable, moving parts and a top-loaded design that provides easy access for disassembly and service

Maximize product safety and process reliability while minimizing costs and contaminant risks with Alfa Laval double-seal valves. Handle both process and CIP fluids at the same time with ease. A great alternative to double-seat mixproof valves, these standardized, cost-effective double shutoff valves come in hygienic and aseptic models and are available in a variety of valve body configurations as shutoff valves.


How does a double seal valve work?

Alfa Laval double seal valves are controlled by means of compressed air from a remote location. The valve is fitted with two pneumatic normally open (NO) valves – a leakage detection valve and a CIP valve. The valve plug has two seals; the space between these seals forms a leakage chamber under atmospheric pressure. The leakage detection valve discharges any product leakage to the leakage chamber. The leakage chamber may be cleaned by supplying a CIP system into the leakage detection valve. The double seal valves are insensitive to water hammer in the product line above the plug.
