ANSI Hard Seal Cast Iron Gate Valve With Size Range 2" to 24", DN50-DN600, PN10/PN16 Pressure Rating for Industrial Pipelines

Chengxin Valve Co., Ltd., a seasoned manufacturer established in 1993, delivers precision-engineered ANSI Hard Seal Cast Iron Gate Valves designed for rigorous industrial pipeline systems. With sizes spanning 2" to 24" (DN50-DN600) and pressure ratings of PN10/PN16, these valves provide exceptional sealing performance and durability in demanding environments. Backed by ISO9001, ISO14000, and OHSAS18001 certifications, our valves ensure reliable flow control for clients across South America, Eastern Europe, Africa, and the Mid East through efficient shipments from major Chinese ports.

Key features and technical advantages include:

• Robust construction using high-grade cast iron for superior corrosion resistance and structural integrity

• Hard seal design minimizes leakage risks even under high-pressure conditions (up to PN16)

• ANSI-standard connections ensure compatibility with global industrial piping systems

• Low-friction operation reduces maintenance frequency and extends service life

• Optional handwheel or gear operation configurations for flexible installation

Technical specifications for standard models:

These valves deliver measurable benefits for industrial operators, including reduced downtime due to their fail-safe sealing mechanism and cost efficiency from minimal maintenance requirements. The hard seal technology prevents particulate buildup in fluid transfer applications, while the full-bore design maintains consistent flow rates. Suitable for water treatment plants, chemical processing, and oil/gas auxiliary systems, they withstand pressures up to 16 bar without performance degradation.

Chengxin Valve supports global logistics from Tianjin, Qingdao, Shanghai, and Ningbo ports, with a 50,000–100,000 m² manufacturing facility ensuring scalable production. Customizable options include alternative sealing materials for specific media compatibility.
