14 Inch 1500LB Pressure Seal Bonnet Butt‑Weld Gate Valve, API600, A216 WCB

This heavy‑duty gate valve is engineered for high‑pressure pipeline systems, with nominal size 14 inch and pressure rating Class 1500. The valve body is cast from ASTM A216 WCB carbon steel, which provides outstanding mechanical strength and pressure resistance at elevated temperatures.

It adopts a classic pressure‑seal bonnet structure. As internal pipeline pressure rises, the sealing force between the bonnet and body will increase automatically, achieving superior zero‑leakage performance under high working pressure. The end connection is butt‑weld (BW), allowing full penetration welding with pipelines to guarantee connection integrity for long‑term operation.

Precision‑machined sealing surfaces reduce wear and friction during valve opening and closing, delivering flexible operation and reliable shut‑off performance. All components are strictly manufactured and inspected in accordance with relevant industrial standards.

Widely applied in power station, thermal power plant, petroleum, petrochemical and other high‑pressure process pipelines for on‑off media flow. Suitable for water, steam, oil and other non‑corrosive fluid media.
