Stainless Steel Clamped Hastelloy Pneumatic wafer Butterfly Valve
A Stainless Steel Clamped Hastelloy Pneumatic Wafer Butterfly Valve is a corrosion-resistant hygienic flow-control device designed for tight spaces and demanding media. It uses a pneumatic actuator to rotate a disc within a wafer-style body, providing rapid, reliable shutoff and smooth regulation in sanitary or chemically aggressive environments.
Working Principles
This 6-inch stainless steel PVC clamp-type solenoid butterfly valve uses a solenoid coil to control the rotation of the valve plate, thus opening and closing the pipeline medium. When the solenoid coil is energized, the magnetic force pushes the valve stem to rotate the butterfly plate, opening the valve and allowing the medium to flow smoothly. When the power is off, a spring or reset mechanism drives the butterfly plate to close, pressing the butterfly plate against the valve seat to form a seal and prevent medium leakage. The valve body is made of a combination of PVC and stainless steel, and the clamp connection allows for quick and easy installation and disassembly. It is suitable for automated control and remote operating systems of water treatment, beverage, food, and chemical liquid pipelines, and features a compact structure and corrosion resistance.
