Sanitary pneumatic butterfly valve

peration options: it can be manually controlled with a locking handle or automatically actuated via a pneumatic actuator. The actuator is available in NC (normally closed), NO (normally open), or double-acting (air/air) types. Its design ensures a reliable 90° rotation with increased torque for tight sealing.

The manual handle allows the valve to be fixed in multiple positions for precise flow regulation. Ideal for sanitary and hygienic applications requiring efficient shut-off and control.

Detailed Description

 

BV6 series Butterfly Valve Operation Options and Actuator Design – Manual and Automated Control

The butterfly valve can be operated either remotely via a pneumatic actuator or manually through a handle, offering flexible solutions for a wide range of process control applications.

The pneumatic actuator is available in three standard configurations:

Normally Closed (NC)

Normally Open (NO)

Double Acting (Air-to-Open / Air-to-Close, A/A)

The actuator design ensures that the axial movement of the piston is converted into a precise 90° rotation of the valve shaft. This mechanism significantly increases the torque when the valve disc makes contact with the seal ring, ensuring a secure shut-off. This enhanced torque provides excellent sealing performance, especially in high-demand hygienic process systems.

For manual operation, the locking handle allows the valve to be mechanically fixed in various positions, including fully open, fully closed, half-open, or other intermediate positions. This feature enables accurate flow regulation and is ideal for applications that require adjustable fluid control.
