Application
▪ This series of butterfly valves is a sanitary, automatic or manual operated butterfly valve suitable for various applications in stainless steel pipeline systems.
Operational principle
▪ This series of butterfly valves can be remotely operated through a pneumatic head or manually operated through a handle.
▪ There are three standard versions of actuators, namely the Normally Closed (NC) type, Normally Open (NO) type, and Air/Air (A/A) type.
▪ The actuator converts the axial motion of a piston into a 90 ° rotation motion of the valve shaft. When the circular disc in the valve body contacts the sealing ring of the butterfly valve, the torque of the actuator increases and the valve is closed.
▪ Selecting different manual operation handles can mechanically lock the valve in the open, close, middle, or other positions to achieve flow adjustment.
Option
▪ Handle: Two position, three position, four position pull rod handle, multi position plastic handle, multi position stainless steel handle
▪ Actuators: stainless steel pneumatic actuators, aluminum pneumatic actuators, electric actuators
