LKB Butterfly Valve

Because of its large opening area and low flow resistance, the trustworthy and sanitary Alfa Laval LKB Butterfly Valve transports low and medium viscosity liquids in stainless steel pipe systems. Choose between a standard handle and a pneumatic actuator to operate manually or automatically. Hygienic applications can be found in a variety of industries, including dairy, food, beverage, and brewing.

Using the Alfa Laval LKB Butterfly Valve series will help you achieve consistent, low-cost flow control and improve your process performance. Low flow limitations allow process fluids, particularly those with high particle concentrations, to pass freely. The LKB, particularly when used with the Alfa Laval ThinkTop V55 and V70 pulse seat clean feature, improves product quality while saving money on energy, water, and cleaning media. Easy to set up and update.

Use optional intelligent valve control modules with auto-setup functionality to quickly bring valves online and optimise flow control. Maintenance is easy and inexpensive replacing a single long-lasting component requires no special tools.

These hygienic butterfly valves are versatile, modular and quick to install, increasing output and end-product quality in a variety of industries including dairy, food, beverage and brewing.

Reliable, cheaply cost butterfly valve for flow control in various sanitary applications in piping systems

• High performance cutoff valve guarantees minimal pressure drop and high Kv value via low flow resistance.
• Particularly for the flange type, maintenance-friendly helps to lower service downtime.
• Reasonable solution for basic flow control
• Economical, space-saving architecture makes inline mounting in plumbing systems simpler.
• Excellent process hygiene resulting from similar components used in the LKB valve validated by EHEDG

The Alfa Laval LKB Butterfly Valve can be operated manually with a handle or remotely using a pneumatic actuator. The actuator comes in three typical configurations: normally closed (NC), normally open (NO), and air/air activated (A/A).

In pneumatic operation, an actuator converts axial piston motion into a shaft rotation of 90 degrees. The actuator torque increases when the valve disc makes contact with the butterfly valve seal ring, ensuring proper valve seat seal.

When operating the valve manually, a handle mechanically locks it in either an open or closed position. Handles are available in two, four, regulating 90° and multi-position configurations. Manual butterfly valves are also equipped with indicators that provide feedback on valve position (open/closed).
