ZF43Y Flat gate valve
The ZF43Y Flat Gate Valve is designed for industrial pipelines requiring straight-through flow and dependable shut-off. Featuring a full-bore flat gate structure, precise machining, and robust materials, it ensures low-pressure loss, smooth operation, and leak-tight sealing. Applicable to water, steam, oil, gas, and chemical media in demanding environments.
Flat gate valve
The ZF43Y Flat Gate Valve is a high-performance isolation valve suitable for various industrial pipelines. Its flat gate design provides full-port flow with minimal resistance, reducing pressure drop and facilitating piggable pipeline operations.
Constructed from carbon steel, stainless steel, or alloy steel, it offers excellent mechanical strength, corrosion resistance, and long service life. The valve can be manually operated or integrated with electric, pneumatic, or hydraulic actuators for automated control.
