The pneumatic hygienic butterfly ball valve is a quarter-turn pneumatic valve engineered for hygienic, clean and high-demand fluid pipeline systems. It combines the sanitary structure of a hygienic butterfly valve and the fast switching characteristics of a ball valve, achieving rapid shut-off, opening and automatic fluid control.
Designed with food and pharmaceutical-grade sanitary standards, the valve features a smooth, dead-space-free internal flow passage that prevents medium accumulation and allows easy cleaning and sterilization. The valve core rotates 0°～90° driven by a pneumatic actuator to realize fast on-off operation.
It is widely used in food & beverage, dairy, pharmaceutical, bio-engineering, daily chemical, beer, drinking water and various clean fluid processing systems.
Working Principle of Pneumatic Hygienic Butterfly Ball Valve
The pneumatic hygienic butterfly ball valve uses a pneumatic actuator as the drive unit. Clean compressed air enters the actuator and drives the internal transmission mechanism to generate 0°～90° quarter-turn torque, rotating the valve stem and butterfly ball cartridge synchronously.
When the through hole of the butterfly ball aligns with the pipeline flow passage, the valve is fully open for smooth medium flow. Rotating the butterfly ball by 90° allows the spherical surface to block the flow passage and shut off the medium.
It can be equipped with solenoid valves, limit switches, air filter regulators and other automation accessories to realize remote on-off control and valve position signal feedback. The single-acting actuator is fitted with an internal spring for automatic reset upon air loss to satisfy fail-safe requirements. The smooth inner flow passage supports CIP/SIP online cleaning and sterilization, suitable for clean process conditions.
Pneumatic Shut‑off Ball Valve are 0‑90° rotary valves. They utilize pneumatic actuators to convert compressed air into rotary motion, delivering fast and reliable valve opening and closing for industrial process control.
According to specific application requirements, pneumatic ball valves can be equipped with solenoid valves, limit switches, position feedback devices, air filter‑regulators, valve positioners and other pneumatic instrument accessories to realize automatic valve control and remote monitoring functions.
Many factors shall be considered when selecting a pneumatic ball valve, including valve size, pressure rating, operating temperature, process medium, flow rate, body material, seat material, actuator type and control mode.
