Lug-type butterfly valve PN10/16: Economical and reliable shut-off

The lug type butterfly valve type AK201 is a butterfly valve with a concentric design that offers maximum reliability at an attractive price – ideally suited for industrial applications and pipelines, without compromising on quality and functionality. The type AK201 is equipped with threaded eyes that enable seamless integration into existing flanged pipe systems. For this reason, it offers greater flexibility in operation compared to the wafer type variant AK200.

Constructed with a robust ductile iron (GGG40 + epoxy 150µm) body, these butterfly valves are suitable for installation between flanges PN10/16 and provide a tight sealing. The disc is made of stainless steel (1.4408) and the shaft of stainless steel (AISI 420), which ensure high corrosion resistance and mechanical strength. Moreover, this butterfly valve can be supplied with different seat materials such as EPDM, NBR, PTFE or Viton, offering flexibility for applications with different media and operating temperatures.

Due to its simple and compact design, cost-effectiveness and reliable sealing performances, this all-round butterfly valve is suitable for use in HVAC systems, water & wastewater sector, oil & gas applications, low-pressure building pipelines, irrigation & agricultural systems, general industry utility pipelines, ash disposal systems, fuel handling, cooling water systems in power generation and many more.

Actuated butterfly valve: pneumatic and electric

The butterfly valve type AK201 can be operated manually using a hand lever or a gearbox, but also automatically with a pneumatic or electric actuator. Thanks to the ISO 5211 top flange, the installation of actuators is both convenient and straightforward. Additionally, a wide range of accessories and options are also available, including limit switch boxes, solenoid valves, positioners, mounting kits & spindle/stem extensions.
