Hard-Seal Rising Stem Cast Steel Gate Valve (Ductile Iron Disc)
Product Introduction
The Hard-Seal Rising Stem Cast Steel Gate Valve is designed for reliable shut-off in medium-high pressure systems. Featuring a WCB cast steel body, ductile iron (GGG50) disc, and hard-faced sealing components, its exposed rising stem provides clear visual indication. Suitable for industrial water treatment, HVAC, and general chemical applications, it operates from -20℃ to 200℃ at PN16/ANSI 150 pressure, achieving bidirectional zero-leakage sealing for DN50-DN400 pipelines.
Product Advantages
- Cost-Effective: Ductile iron disc ensures performance at lower cost than all-steel valves.
- Reliable Sealing: Hard-faced sealing maintains Class IV leakage after prolonged use.
- User-Friendly: Rising stem shows position clearly; 2Cr13 stem resists corrosion.
- Wide Compatibility: Ideal for water, steam, oil, and other industrial media.
Product Features
High-Strength Materials
WCB body offers excellent pressure resistance; GGG50 disc combines casting advantages with steel-like strength.
01
Hard-Seal Technology
Hard-alloy welded disc face (≥HRC40) provides 2x longer service life than standard gates.
02
Durable Rising Stem
2Cr13 stainless steel stem with integrated trapezoidal threads reduces operating torque by 20%.
03
Easy Maintenance
Split bonnet and packing chamber enable quick seal replacement, cutting downtime by 50%.
04
Flow Optimized
Full-bore design reduces pressure loss by 15% with 1.1x higher Kv value.
