Rising Stem Fire Protection Gate Valve
Product Introduction
Designed for fire water supply and emergency pipelines, this rising stem fire protection gate valve features a ductile iron body with fully exposed stem mechanism, enabling rapid operation and visual status confirmation. The linearly moving stem with high-visibility scale markings is ideal for fire hydrants and pump rooms. EPDM resilient seats ensure bidirectional bubble-tight sealing at PN16 pressure (-20℃~80℃), compatible with water and foam mixtures. Triple-layer anti-corrosion coating withstands humid and saline environments.
Product Advantages
1. Fire-Rated Reliability: Passes -30℃ low-temperature operation test.
2. Low Maintenance: Quick-release bonnet reduces seal replacement time by 60%.
3. Extended Durability: 2Cr13 stainless steel stem withstands 100,000+ cycles.
4. Smart Adaptability: Pre-drilled mounting points for actuator retrofitting.
