IntroductionFeaturesHow It WorksDocumentation
Koltek Valve
The Alfa Laval Koltek Valve is designed to control the flow of items that are particularly thick or include large particles. This space-saving diverter shutter valve transfers processing fluids with the highest purity and minimal pressure loss. Its ease of maintenance extends to cases where it is welded directly into a pipeline.
Allow for the smooth passage of highly viscous fluids containing large particles through your processing lines. Process industries with strict cleanliness and performance requirements frequently use the Alfa Laval Koltek Valve, a stainless steel diverter shutter valve.
This flexible valve, also known as the MH Koltek shutter valve, features three ports for easy in-line flow diversion. The valve is simple to use, fix, and even automate if required. It finds widespread use in the pharmaceutical, food and beverage, chemical, and home and personal care industries.
Alfa Laval Koltek Shutter Valve Application
- Reduced pressure drop and simplified internal contours ensure continuous inline flow, hence improving process hygiene and efficiency.
- Make the most of your processes by managing the flow of very viscous fluids and improving their efficiency.
- A three-way inline valve can provide greater routing options.
- Allow high-viscosity and large-particle process fluids to move through more easily, increasing yields.
- Installing a valve with one port in the vertical (down) position promotes process hygiene and reduces product losses caused by total drainability.

The standard design
The Koltek valve features a PTFE shutter, three pipe connection ports, an internal cylindrical bore, and a strong body. The shutter is supported and set by an internal shaft, which is guided by rings or bearings on the two lids. The shaft can be turned manually using the stainless-steel handle or automatically using the actuator. A gear wheel on the valve shaft engages a toothed bar connected to a set of cylinders and one or two major pistons in the actuator. Pressure shocks in the valve do not affect the system.
Working Principle
The Alfa Laval Koltek Valve is operated by an actuator or handle. A spring mechanism presses the shutter against the inner cylindrical surface of the valve body, ensuring perfect sealing.
An indicator device can be mounted laterally to the air-actuated valve to remotely indicate the valve position, or an Alfa Laval ThinkTop® V50 or V70 control unit can be used.
On the side of the manually controlled valve, you’ll discover indication units for Alfa Laval LKLA actuators. The valve actuator is available in both single-acting and double-acting configurations. The single-acting actuator is powered by a single piston, whereas the double-acting actuator is powered by two.
