The pneumatic sanitary butterfly valve is engineered for stainless steel pipeline systems that require strict hygienic control. It supports both pneumatic actuation and manual operation, making it versatile for automated production lines and manual process control. Valve body material is 304 or 316L stainless steel, with internal surface finish Ra ≤ 0.8μm to meet sanitary requirements.
All seal materials comply with FDA 177.2600 standards. The valve is available in multiple connection standards — DIN, SMS, RJT, ISO, IDF, and 3A — and can be configured with pneumatic stainless steel actuators, pneumatic aluminum actuators, or electric actuators.
As a trusted valve exporter to 60+ countries, KONTE provides bulk supply, custom configurations, and OEM/ODM manufacturing services for distributors and project contractors worldwide.

▶This series butterfly valve is either remote-controlled by means of an actuator or manually operated by means of a handle.
▶The actuator is made in three standard versions, normally closed(NC), normally open (NO) and air/air activated (A/A).
▶The actuator is designed so that an axial movement of a piston is transformed into a 90°rotation of a shaft.The torque of the actuator is increased when the valve disc contacts the seal ring of the
butterfly valve.valve is closed.
▶Selected The handle for manual operation mechanically can lock the valve in open,close,middle or other positions to control the flow rate.
