Flat Gate Valve with Diversion Hole – Detailed Overview A flat gate valve with diversion hole is a specialized valve designed to provide reliable flow control and isolation in pipeline systems where pressure equalization and smooth flow transition are essential. The unique feature of a diversion hole (or pressure equalizing hole) in the gate allows for gradual pressure balancing during valve operation, reducing hydraulic shock and minimizing wear on the valve components. Design and Working Principle Flat Gate Design : Unlike wedge or parallel gates, the flat gate provides a simple, sturdy barrier for fluid shutoff, offering a straightforward sealing surface. Diversion Hole Functionality : The incorporated hole in the gate facilitates pressure equalization between the upstream and downstream sides when the valve is partially open or during operation, preventing sudden pressure surges and reducing the risk of water hammer or pipeline stress. Body and Material : Commonly manufactured from cast steel (such as WCB or WCC), stainless steel, or alloy materials to withstand diverse industrial conditions including high pressure and corrosive media. ...
