Forged steel valve is a kind of high quality valve manufactured by forging process, widely used in various industrial fields. Forging process through high temperature heating and plastic deformation, to achieve the desired shape and properties of the metal material. This process enables forged steel valves to have higher strength, better corrosion resistance and longer service life. Forged steel valve is mainly composed of body, cover, stem, disc (or wedge), sealing ring and other components. According to different application requirements, forged steel valves can be divided into many types, such as forged steel gate valve, forged steel globe valve, forged steel ball valve, forged steel check valve. Each type of valve has specific application and functional characteristics.
Valve Overview
Forged steel globe valve is a commonly used shutoff valve, mainly used to connect or shut off the medium in the pipeline, and is generally not used to adjust the flow. The globe valve is applicable to a wide range of pressure and temperature. This valve is suitable for small-diameter pipelines, the sealing surface is not easy to wear and scratch, the sealing performance is good, the valve disc stroke is small when opening and closing, the opening and closing time is short, and the valve height is small.
Forged steel gate valve refers to a valve whose closing part (gate) moves in the vertical direction along the center line of the passage.
The opening and closing part of the forged steel gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The forged steel gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate of the forged steel gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters. The driving modes of forged steel gate valves are: manual, pneumatic, electric, and gas-liquid linkage. Gate valves are divided into cast iron gate valves, ductile iron gate valves, stainless steel gate valves, forged steel gate valves, etc. according to the material.
Forged steel check valve refers to a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the backflow of the medium. It is also called non-return valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the pump and drive motor from reversing, and the release of the container medium. Check valve can also be used to provide supply to the auxiliary system where the pressure may rise to exceed the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
The forging process makes the internal structure of the metal material more dense, the defects such as porosity and shrinkage in castings are eliminated, thus, the overall strength of the valve is significantly improved.
It can withstand higher working pressures and temperatures, suitable for applications in high pressure and high temperature environments.
Forged steel valves are usually made of high-quality stainless steel or other corrosion-resistant materials and have good corrosion resistance.
Even if works in bad environment, such as chemical, oil, natural gas and other industries, which can maintain stable operation for a long time.
Reasonable design and high quality materials and advanced processing technology, make it have a long service life.
When maintained properly, the service life can reach several decades.
The sealing is machining precisely, with high performance seal material, which can achieve highest seal effect.
In the close state, it can prevent media leakage to ensure the system can operation safety and reliable.
The design takes into account easy operation, whether manual or automatic control, which can achieve the open and close action easily.
Some advanced forged steel valves are also equipped with electric, pneumatic or hydraulic actuators, further improve the operation flexibility and level of automation.
Widely used in petroleum, chemical, electric power, metallurgy, shipbuilding, water treatment and other industries.
No matter transporting liquid, gas or steam, forged steel valves provide a reliable solution.
Simple structure and easy to disassemble and assemble for regular inspection and maintenance.
When a failure does occur, replace damaged parts to restore their function to reduce maintain cost and time.
The design meet the international and national standard, after strict quality testing and certification to ensure safety during use.
