As one of the most widely used shut-off valves in industrial pipeline systems, the gate valve is valued for its simple structure, low flow resistance, and broad applicability across oil and gas, chemical processing, power generation, water treatment, and other industries. However, like any type of valve, a gate valve has both strengths and inherent limitations. Understanding these advantages and d...

Gate valves are among the most commonly used shut-off valves in industrial piping systems. With their simple structure, low flow resistance, and reliable sealing performance, they are widely applied in the energy, petrochemical, water treatment, and metallurgical industries. However, a gate valve is not a “universal solution.” Using the wrong medium, incorrect installation, or operatin...

In industrial piping systems, the gate valve is one of the most widely used valves. Its key advantage lies in providing either a fully open flow path or a complete shutdown, ensuring excellent sealing performance with minimal pressure drop. Because of this, gate valves are regarded as the “gatekeepers” of safe system operation in critical industries such as power generation, petrochemi...

Introduction In industrial fluid control systems, gate valves, as a type of shut-off valve, have long played a key role in opening and closing operations. With increasingly complex operating conditions, higher demands are being placed on valves in terms of corrosion resistance, wear resistance, and service life.   Among the many available materials, duplex stainless steel (ASTM A995 5A) combi...
