Hard Seal Wedge Gate Valves

Wedge gate valve is a high-performance valve widely used in petroleum, chemical, electric power, metallurgy, water supply and drainage and municipal engineering and other working conditions. The valve is suitable for water, steam, oil, gas and a variety of corrosive media, with excellent pressure resistance, high temperature resistance and sealing performance. The wedge gate valve adopts wedge gate design, which can realize two-way sealing, and the gate plate closely fits the valve seat when the valve is closed, ensuring no leakage. Product features include sturdy structure, flexible opening and closing, reliable sealing, small flow resistance, suitable for fully open or fully closed conditions. The wedge gate valve supports manual, electric and pneumatic drive methods to meet the needs of automation control. Its main function is to realize the cut-off and connection of pipeline media, to ensure the safe and stable operation of the system. With excellent durability and sealing performance, wedge gate valves have become an indispensable high-quality valve equipment in industrial processes and critical piping systems.

Hard Seal Wedge Gate Valves

Model: Z41H/Z41Y

Subtitle：Carbon steel gate valve

Our hard seal wedge gate valve is designed for critical service applications requiring a metal-to-metal seal (no elastomers). It utilizes a precision-machined, solid wedge design to provide gas-tight shutoff in high-pressure, high-temperature, and abrasive media applications where soft-seat valves are prone to premature failure.
