Stainless Steel Wafer Butterfly Valve D373W

Features

1. This butterfly valve boasts a simple structure, compact size, light weight, low material consumption and small installation space. It realizes 90° reciprocating quick opening/closing with low driving torque. It is widely used for cutting off, connecting and regulating pipeline medium, and delivers excellent fluid control and tight shut-off performance.

2. It can be used for slurry transportation, leaving minimal residual liquid inside pipeline cavities. It maintains excellent sealing and regulating performance even under low pressure conditions.

3. Streamlined disc design minimizes fluid resistance loss, making it an energy-efficient valve product.

4. The stem adopts a solid structure with optimized heat treatment, providing excellent comprehensive mechanical performance, corrosion resistance and wear resistance. During opening and closing cycles, the stem only performs rotational movement without vertical displacement, greatly protecting packing and ensuring reliable sealing. It is permanently locked to the butterfly plate, and the external end is designed with an anti-blowout structure to prevent accidental stem ejection under connection failure.

5. Available connection types: flanged, wafer, butt weld and lug wafer connection. Actuator options include handwheel, worm gear, electric, pneumatic, hydraulic and electro-hydraulic drive, supporting remote control and fully automatic operation.

 Advantages

1. Fast and labor-saving opening/closing, low fluid resistance, suitable for frequent cyclic operation.

2. Simple construction, compact overall dimensions, short face-to-face length, light weight, perfectly suited for large-diameter pipeline applications.

3. Excellent performance for slurry handling, with extremely low residual liquid retention in pipelines.
