The MZY Rising Stem Cast Iron Copper-Inlaid Round Gate Valve is engineered for superior interception and water level regulation in demanding applications including municipal water supply, drainage systems, flood control, and hydropower projects.
Product Overview
This high-performance gate valve covers an extensive size range from Dn200 to Dn3000, with main body construction using premium Gray Cast Iron (HT250) or Ductile Iron (QT450-10). The unique outer arc design ensures uniform stress distribution and significantly enhanced pressure resistance.
Core Technology
Precision-machined sealing surfaces utilize Tin Bronze or NBR materials, maintaining sealing clearance to ≤ 0.1mm for perfect plane contact sealing. The innovative adjustable modular wedge mechanism allows easy restoration of sealing performance without major disassembly.
Gray Iron (HT250) / Ductile Iron (QT450-10) / Stainless Steel
Seal & Wedge Material
Tin Bronze (ZCuSn5PbZn5) or NBR (Nitrile Rubber)
Opening/Closing Speed
0.2 m/min ~ 1.5 m/min
Key Applications
Municipal Water Supply and Wastewater Treatment
Fully adaptable to complex water conditions with pH range of 5 to 10. Combined with highly corrosion-resistant body construction, ideal for pipeline interception, sedimentation tank control, and water flow management in sewage treatment plants.
Water Conservancy and Flood Control
Withstands 10m working water head in both directions and features high-strength outer arc gate plate structure for safe, stable water level regulation even under high-water-level scouring during flood seasons.
Agricultural Irrigation and Pumping Stations
Compatible with manual, electric, or pneumatic-hydraulic hoists for smooth vertical lifting operations, precisely controlling water release and shut-off in large underground pipe networks, irrigation canals, and pumping stations.
Frequently Asked Questions
How can I resolve a decrease in sealing performance after long-term operation?
The MZY round gate valve features a special adjustable modular wedge mechanism. When wear causes water-stopping performance decline, no large-scale disassembly or gate replacement is needed. Simply adjust the wedge blocks within the module to restore factory-level sealing performance.
Is this round gate valve suitable for large-diameter deep-water pipeline interception?
Absolutely. This series covers ultra-large diameters up to Dn3000. Under bi-directional pressure configuration, it withstands up to 10m of water head pressure in both directions. The highly rigid guide rails and frame structure meet high-pressure interception requirements for deep-water, large-diameter pipelines.
