Z81X-16Q A high-performance shut-off valve engineered for industrial and municipal piping systems, the Z81X-16Q Manual Grooved Stem Soft Seal Gate Valve is constructed with premium ductile iron (DI) – boasting exceptional tensile strength, impact resistance, and corrosion resistance, far outperforming traditional cast iron valves in durability and service life. Featuring a grooved stem design combined with soft seal technology, this gate valve ensures tight shut-off and zero leakage. The EPDM soft seal seat and gate provide excellent sealing performance, while reducing friction during operation for smooth, labor-saving manual control. The grooved connection enables quick, tool-free installation and disassembly, significantly improving on-site construction efficiency and lowering maintenance costs. Designed to handle working pressures up to 1.6MPa and temperatures ranging from -10°C to 120°C, the valve is suitable for water supply and drainage, heating, HVAC, fire protection, municipal engineering, and industrial pipeline systems. It efficiently controls the flow of water, sewage, and neutral liquids, preventing medium leakage and ensuring system stability. Compliant with national and international standards (GB/T), the Z81X-16Q valve integrates rugged construction with user-friendly design. Its compact structure saves installation space, while the ductile iron body resists wear, corrosion, and harsh operating conditions. As a professional valve manufacturer with integrated industry-trade capabilities, we offer custom specifications, OEM/ODM services, and one-stop solutions from production to after-sales support to meet diverse project needs.
Z81X-16P stainless steel grooved gate valve delivers zero-leak soft-seal performance up to 1.6MPa, 0–80°C; corrosion-resistant (epoxy + SS304/316), CE/ISO9001/14001/45001 certified. Trusted by 300+ water & chemical plants. Request Technical Demo.
