Forged Steel 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.

Product Overview

The Forged Steel Gate Valve is a high performance solution designed for extreme pressure and temperature applications in the oil and gas, petrochemical and power generation industries. It is manufactured using precision forging for superior strength, durability and leak-proof sealing and is ideally suited for critical isolation tasks in harsh environments. The valve is strictly for on/off service and is not suitable for throttling.

working condition

Oil and gas: wellhead isolation, pipeline shutdown and refinery applications.

Petrochemical: High pressure fluid control in chemical reactors and distillation units.

Power generation: steam isolation in turbines and boiler feedwater systems.

Ships: offshore platforms and ship piping systems.

Comparison with Cast Steel Valves

specificities	Forged Steel Gate Valves	Cast steel gate valve
dissociation	Higher (forged grain structure)	Lower (risk of porosity during casting)
pressure rating	Up to ANSI 2500	Up to ANSI 900
appliance	Critical High Voltage Systems	General industrial use
(manufacturing, production etc) costs	Higher initial investment	Lower upfront costs

Medium of use

petroleum, petrochemical, vapor

working condition

chemical plant, power plants, petrochemical industry, high temperature and pressure, High-temperature and high-pressure working conditions, High Temperature High Pressure Steam System

summarize

Forged steel gate valves offer unmatched reliability in high pressure, high temperature isolation applications. Its rugged forged construction and API 600 compliance make it the gold standard for critical systems in the oil and gas, power plant and chemical industries. Not suitable for flow regulation.
