Wafer Type Thin Ball Valve
The wafer type thin ball valve is connected between two pipe flanges using double-headed bolts. It has a simple structure, small size, and light weight, composed of only a few parts. It can be quickly opened and closed by rotating 90°, with simple operation and good flow control characteristics. When the ball valve is in the open position, the valve core has no resistance, thus the pressure drop through the valve is very low, providing good flow control characteristics.
Applications: Widely used in petroleum, chemical, metallurgy, power stations, light industry, and other fields, for automatic control or cut-off control of oil, water, gas, paper pulp, or fibrous fluids.

Wafer Ball Valve Features
Anti-blow-out stem design
Anti-static design
Pressure balance hole
Automatic packing adjustment design
High platform in accordance with ISO 5211 design
Optional fireproof design
The valve body has an integrated structure, with precise machining and assembly. The ball core is installed from one end, tightened with a ring, ensuring good contact and sealing between the soft sealing seat and the ball core. At the same time, the ring gasket also achieves good sealing, making the valve leak-free during operation.
Due to the integrated structure of the valve body, this valve achieves a short flange distance and significantly reduces the overall weight, only about 50% of that of similar general ball valves.
