Aluminium Pneumatic Actuator Powered Sanitary Stainless Steel Butterfly Valves Weld Connection End

Quick Details:

• Butterfly type configuration
• Comprehensive range of elastomer seals with thermal stability and crrosion resistance
• Hygienic 304 / 316L stainless steel with high tensile strength
• Highly polished stainless steel disc Ra<0.8µm
• Pneumatic actuator ensures efficient and reliable opening and closing

Design Highlights:

• Aluminum Pneumatic Actuator: light weight, cost saving
• Intelligent control mode of spring return or double acting (NC or NO)
• Butterfly valve body: easy installation, fast disassembly
• Weld end: much firmer & strong connection to kill leakage problem and flow retention

​Working Principle:

A. Spring Return Mode: Inlet air pressure drives piston outwards, the gear rotates accordingly to open the valve; when air pressure reduces, spring forces piton backwards, valve stem turn together with the gear to close the valve

B. Double Acting Mode: Compressed air enters the chamber through 2" inlet and gets out of 4" outlet, valve is opened; compressed air enters the chamber through 4" inlet and gets out of 2" outlet, valve is closed
