Design Features
Design standard: API 6D、GB/T 12224
During closing, no relative friction appears between the plug and the valve body sealing face.
The valves have large flow area, small flow resistance, and high sealing pair hardness.
The valve body and plug sealing faces can be overlayed or sprayed with high-hardness, corrosion-resisting alloy materials.
With small opening and closing torque, which is only 1/2 to 1/3 of that of the gate valve, and with short opening/closing time, which only is 1/5 to 1/10 of that of the gate valve.
