Koltek Valves

Control the flow of highly viscous products or products containing large particles with the Alfa Laval Koltek Valve. Compact and hygienic, this diverter shutter valve transfers processing fluids while ensuring minimal pressure loss and maximum hygiene. It is also easy to maintain, even when welded directly into a pipeline

Boost productivity with reliable flow control of high-viscosity and particulate-containing fluids

  • Enhance productivity and process hygiene due to low pressure drop and streamlined internal contours that ensure continuous inline flow
  • Achieve optimal flow and greater process efficiency due to effective handling of highly viscous fluids
  • Increase routing flexibility using a three-way inline valve
  • Promote easy flow and higher yields of high-viscosity process fluids and process fluids with large particles
  • Ensure process hygiene and reduce product losses due to complete drainability when the installed valve has one port in the vertical (down) position

Let highly viscous fluids and fluids containing large particles flow effortlessly through your processing lines. The Alfa Laval Koltek Valve is a stainless-steel diverter shutter valve used in process industries with stringent requirements on hygiene and performance.

Also known as the MH Koltek shutter valve, it is a flexible valve with a three-port flow for easy in-line flow diversion. The valve is easy to operate, maintain and upgrade from manual to automated operation. It is widely used in the food, beverage, chemical, home-personal care, and pharmaceutical industries.

How it works

The Alfa Laval Koltek Valve is manually or pneumatically operated valve. The air-actuated valve can be fitted with an Alfa Laval ThinkTop® V50 or V70 control unit, or an indication unit installed laterally for remote indication of the valve position.


The manually operated valve can be fitted with indication units (used for Alfa Laval LKLA actuators) installed laterally. The valve actuator is available in two versions: a single-acting actuator or a double-acting actuator. The single-acting actuator operates with one main piston, whereas the double-acting actuator operates with two main pistons.
