Ductile iron gate valves are the preferred valve for DN150 municipal water pipelines due to their high strength, corrosion resistance, and low cost. Grade QT450-10 ductile iron offers tensile strength

The SS316L non‑rising stem gate valve DN80 (3″) is ideal for space‑limited piping in corrosive services. Its stem does not lift, saving headroom.

Some gate valves pass the pressure test but leak as soon as they go into service. The problem is often not the valve quality, but incorrect installation or operation.

Gate valves are often considered bidirectional. Many think direction doesn’t matter. But installing a gate valve backwards brings three real problems.

Gate valves come in two main types: rising stem and non‑rising stem. The difference seems small, but picking the wrong one for your site can cost time and money.
