特点

1、Compact Structure, High Pressure Resistance: Featuring a flanged connection structure, the valve body possesses high rigidity, enabling it to withstand significant pipeline stress and medium pressure, making it suitable for medium to high-pressure conditions. The overall design is compact and relatively lightweight.

2、Quick Opening and Closing, Low Operating Torque: Employing a 90° rotary operation, the valve opens and closes rapidly and smoothly. The metal sealing pair, enhanced by a multi-layer sealing structure design, reduces friction between the disc and the seat, effectively lowering the operating torque.

3、Low Fluid Resistance, Significant Energy Saving: When the valve is fully open, the thickness direction of the disc aligns parallel to the flow direction of the medium, creating minimal obstruction to the fluid. The pressure loss approaches zero, offering excellent energy-saving benefits.

4、Reliable Sealing Performance, High Temperature and Wear Resistance: Utilizing a multi-layer metal hard seal structure, the sealing pair consists of stainless steel and temperature-resistant alloy materials. Zero-leakage sealing is achieved through elastic deformation. This structure is resistant to high temperatures, wear, and erosion, ensuring a long service life.

5、Easy Maintenance, Low Inspection and Repair Costs: The valve body features an integral or split design, facilitating easy inspection and replacement of internal sealing components. The seal ring is designed to be replaceable, allowing for on-site maintenance without needing to disassemble the entire valve, effectively reducing maintenance costs.

6、Wide Applicability: The valve body can be made from materials like carbon steel or stainless steel. The sealing surface can be overlaid with hard alloy or sprayed with wear-resistant materials. This allows the valve to be suitable for demanding conditions involving high temperatures, high pressures, and corrosive media. It is widely used in pipeline systems across industries such as petroleum, chemical, metallurgy, and power.
