20–150# Electric Double-Block-and-Bleed DIB Internally Supported Cast Steel Plug Valve (General‑Purpose Valve)

The DIB internally‑supported plug valve achieves positive sealing through an internally‑actuated sliding disc; its opening and closing action does not abrade the sealing surfaces. Featuring dual valve seats with independent sealing and a cavity‑relief feature, it provides single‑unit double‑block-and‑bleed isolation. With a full‑bore design, it supports line‑cleaning and in‑service seal replacement, making it well suited for critical isolation applications involving flammable and explosive media.

2.5–150# Full-bore, soft‑and‑hard double‑seal swing check valve for long-distance pipelines

The swing-type soft-seal check valve features a pivoting‑plate design: the disc opens under the thrust of the fluid flow and closes by gravity and back pressure when the flow reverses. The disc is fitted with a rubber or PTFE soft seal that forms a tight, leak‑free interface with the valve seat, ensuring excellent sealing performance. Its straight‑through flow path provides smooth flow, low fluid resistance, and gentle opening and closing, minimizing water hammer. The valve body is available in cast steel, cast iron, stainless steel, and other materials; installation is not restricted by flow direction, making it suitable for water supply and drainage, gas, chemical, HVAC, and other piping systems to prevent backflow. It can be installed horizontally or vertically in multiple operating conditions.
