Product Description

 **Product Overview**  
The **Grooved Non-Rising Stem Gate Valve** is engineered for fire protection, water supply/drainage, and industrial piping systems. Featuring a clamp-type grooved connection and a concealed stem design, it combines rapid installation, high sealing performance, and extended durability, making it ideal for confined spaces and high-safety applications.  


**Key Advantages**  
Concealed Stem Design**: The stem is fully embedded within the valve body, eliminating external damage risks in tight spaces like underground utility tunnels or equipment rooms.  
Grooved Clamp Connection**: No welding required - installation efficiency improves by 60%, reducing labor and construction costs.  
High-Pressure Sealing**: FKM/EPDM seals withstand up to PN25 (2.5MPa), validated by GB/T 13927 leakage tests.  
Fire Safety Compliance**: Meets GB 5135.6 fire valve standards (CCCF certification available upon request).  
Corrosion Resistance**: 304/316L stainless steel or ductile iron (hot-dip galvanized) body ensures 10+ years of service in humid or mildly corrosive environments.
