Gate Valve (Sürgülü Siyirtmə)

The gate valve is a type of shut-off valve used for the complete opening or closing of liquid flow in water supply, HVAC, fire protection, and industrial piping systems. The working principle of the valve is based on the vertical movement of a gate located inside the body, which opens or closes the flow path. In the fully open position, resistance to liquid flow is minimal. Therefore, gate valves are primarily intended for full opening and closing operations rather than flow regulation.

Products are available in various nominal diameters and pressure classes depending on project requirements. The body material can be made of gray cast iron, ductile iron, or other suitable materials depending on the model. Sealing elements and structural parts are designed for reliable operation and long-term service.

Gate valves can be operated manually with a handwheel or with suitable actuating mechanisms. Flanged connections facilitate installation into piping systems. Models used in fire protection systems should be selected according to relevant project requirements and applicable standards. UL Listed and FM Approved certifications should be verified based on the approval documents of the specific product model.

These valves are widely used in fire water supply lines, pump stations, water distribution networks, industrial facilities, and other engineering systems.
