Alfa Laval Koltek ValvesAlfa Laval Koltek Valves

The Alfa Laval Koltek Valve is a highly versatile shutter valve engineered for demanding fluid handling processes. Whether you're working with highly viscous fluids, products containing large particles, or systems requiring minimal pressure loss, the Alfa Laval Koltek Shutter Valve delivers reliable, hygienic, and efficient performance. It is ideal for use in the food, pharmaceutical, chemical, and other sanitary industries where operational flexibility and cleanability are essential.



 

 

Features

  

Benefits
  • Robust valve body with a precision-machined cylindrical bore for consistent flow
  • Manual stainless-steel handle or pneumatic actuator for operational control
  • Actuator mechanism includes cylinders and one or two main pistons connected to a toothed bar that engages with a gear wheel on the valve shaft
  • Pressure shock-resistant system ensures stable performance under varying conditions
  
  • Versatile three-port fluid handling valve for flexible in-line flow diversion
  • Minimized pressure loss
  • Hygienic design
  • Capable of handling products highly viscous, contain large particles, or have strict requirements to minimize pressure loss

How does Koltek Valves work?
The Koltek Valve is controlled either manually via a handle or automatically through a pneumatic actuator. A spring mechanism presses the PTFE shutter securely against the inner cylindrical surface of the valve body, forming a tight, leak-free seal.

For automation, the Alfa Laval Koltek Valve can be paired with an Alfa Laval ThinkTop® V50 or V70 control unit or laterally mounted indication units for remote valve status monitoring. In manual versions, indication units compatible with Alfa Laval LKLA actuators can be added for visual feedback.

Two actuator types are offered:
Single-acting actuator: One main piston
Double-acting actuator: Two main pistons

FAQ
