Pneumatic Wafer Ball Valve Product Overview
The Q671F Pneumatic Wafer Ball Valve is a product in the pneumatic ball valve series, also known as the pneumatic ultra-thin ball valve. It is a new generation of pneumatic ultra-short flange ball valve developed by our company through the introduction of Italian technology and localized design. The ball core channel shapes include rectangular, V-shaped, and O-shaped. The pneumatic wafer ball valve features a compact structure, small size, light weight, and easy installation. The wafer-type pneumatic ball valve is a new type of ultra-short flange distance ball valve developed by absorbing Italian technology and localized design. The pneumatic wafer ball valve, or pneumatic ultra-thin ball valve, uses a direct connection method for actuator linkage, offering advantages such as compact structure, small dimensions, light weight, low friction resistance, minimal hysteresis, and stable and reliable operation. The pneumatic wafer ball valve can be widely used in petroleum, chemical, metallurgical, power station, light industry, and other fields for automatic regulation or shut-off control of oil, water, gas, pulp, or fibrous fluids.
