Non-diversion flat gate valve
The Non-Diversion Flat Gate Valve is designed for straight-through flow systems requiring full shut-off without bypass channels. Its flat gate structure provides minimal pressure drop, smooth operation, and durable sealing. Suitable for water, steam, oil, and chemical pipelines, it offers low maintenance, high reliability, and integration with automation systems.
Non-diversion flat gate valve
The Non-Diversion Flat Gate Valve is a high-performance isolation valve designed for pipelines where a straight, unobstructed flow path is required. Unlike diversion-type valves, it does not have a pressure-balancing or bypass hole, making it ideal for applications requiring direct flow without turbulence.
Constructed from carbon steel, stainless steel, or alloy steel, it provides excellent mechanical strength, corrosion resistance, and bi-directional sealing. The valve can be operated manually, electrically, pneumatically, or hydraulically and is compatible with automated control systems.
