The Automatic Pneumatic Butterfly Valve Type 57 is a quarter-turn valve with equal percentage type flow characteristics that is ideal for chemical processing and wastewater applications. Its spherical symmetric design of the disc allows smooth operation, reduces flow turbulences, and achieves excellent CV values. The massive sealing design overcomes problems that may occur in case of slurry in the media. The valve provides moderate flow control and therefore can be used in both on/off and modulating services. Plastic construction gives the valve superior corrosion resistance.
Horizontal Type Actuator saves Piping Space.
Spring unit for Air to Open & Close is detachable so Change-Over between Double-acting and Air to Open & Close can be done Easily.
Various Options can be Easily installed or removed, and can be mounted later (except Positioners).
Stopper enables Adjustment of ±5 Degree at Fully-Open or Fully-Close position.
