Hygienic butterfly valve

Application

This series of butterfly valves is a type of sanitary, automatic or manual-operated butterfly valve, suitable for various applications within stainless steel piping systems. 

Working principle

This series of butterfly valves can be remotely controlled via an air actuator, or manually operated by a handle. 

The actuator comes in three standard models: normally closed (NC) type, normally open (NO) type, and air/air (A/A) type. 

The actuator converts the axial movement of a piston into a 90° rotation of the valve shaft. When the circular butterfly plate inside the valve body comes into contact with the sealing ring of the valve, the torque of the actuator increases, causing the valve to close. 

By selecting different manual operation handles, the valve can be mechanically locked in the open, closed, intermediate or other positions, enabling the regulation of the flow rate. 

Options

▪ Handle: Two-position, three-position, four-position pull lever handle, multi-position plastic handle, multi-position stainless steel handle 

▪ Actuator: Stainless steel pneumatic actuator, aluminum pneumatic actuator, electric actuator
