Forged Steel Valves

SIO manufactures one of the best forged steel valves in the market. Forged steel valves are made through the forging method. This method will involve forming alloys and metals while they are in their solid state. Heat and industrial tools and equipment provide compressing pressure to bend the alloys and metals. Dies are utilized as well to trim and shape them to make specific valves. Forging can be done in varying temperatures, depending on the material used.

Forged steel valves are known for their strength, which makes them perfect for high-pressure applications. They come with less thickness of their walls, which decreases the chances of problems, like thermal fatigue, during operation.

You can depend on SIO to provide you with high-quality forged steels that are available in various materials and compositions.

    Forged Steel Valves Manufacturer

    Forged steel valves manufactured by SIO play a crucial role in determining the level and time of productivity of industrial appliances produced using two methods; forging and casting.

    Under the forging method, cast steel valves are made using a meticulous process that shapes the steel in solid form with the help of machinery. The steel is bent using high compression and cut with dies, creating a range of valves. The valves thus produced have high strength and less thickness, lowering the chances of thermal fatigue and increasing the ability to handle stressful systems.

    The forged steel globe valves supplied by SIO are suitable for throttling, and isolating services as their seats are easily machined and the installation is straightforward. Due to their simple linear-motion design, they are easy to open and close and provide tight shut-offs.

    Vacuum Service

    SIO forged steel valves are suitable for vacuum applications because they provide tight sealing with zero leakage. They are also helpful in preventing any backflow and contamination.

    High-Pressure Service

    Our forged steel ball and check valves possess enhanced strength and high tolerance against severe working environments, such as high pressures and toxic media. Since they are compact and sturdy, you can use them for applications dealing with high pressures such as oil refineries, power generation, LPG & LNG plants, and more.

    High Temperature Service

    Our forged steel valve features a thin wall which makes it perfect for varying temperatures, even after continued usage. As they are made up of quality steel, they are robust and have high tolerance at different temperatures, making them suitable for use in chemical petrochemical and other industrial services.

    What are the Different Types of Forged Steel Valves?

    As one of the leading manufacturers of forged steel valves, SIO offers different types of forged steel valves to meet your needs.

    Forged Steel Gate Valve

    In process plants, the SIO forged steel gate valve is used for starting and stopping the flow of fluid. They are best for handling varied pressures and temperatures, and since they work slow, the risk of water hammering is eliminated.

    Forged Steel Globe Valve

    In the systems where flow control and leak tightness are necessary, SIO globe valves start, stop, and regulate fluid flow. They add more strength and tolerance to varying temperatures, making them perfect for controlling the media flow in severe conditions.

    Forged Steel Check Valve

    In a piping system, forged steel check valves produced by SIO prevent the backflow by pressuring it to pass through the pipeline by opening and closing reversal flow. It works as a non-return valve, allowing the media in a single direction.

    Forged Steel Ball Valve

    Forged ball valves are used for starting and stopping the flow of media, providing strength and tolerance against severe conditions. They have a hollow center to allow media passage when aligned with pipelines and obstruction in the perpendicular state.

    What Is a Forged Steel Valve?

    A forged steel valve is a type of valve that consists of components created through closed die forging. This process involves shaping billets while in their solid state after heating. Forging dies are utilized to press the heated billets to produce the required dimensions and shapes.

    After forging, valve components possess more strength, making them suitable for systems that handle high pressures and temperatures. This process eliminates problems, such as cracks, porosity, and shrinkage, which are common problems of casting steel. 

    Apart from enhanced strength, a forged steel valve has less wall thickness. This reduces the chances of thermal fatigue during valve operation and allows the valves to be cooled and heated quickly. As a result, a forged steel valve is capable of handling stressful systems that continually shifts from startup and phase-down processes.

    Different Types of Forged Steel Valves

    As one of the leading manufacturers of forged steel valves, SIO offers different types of forged steel valves to meet your needs.

    Forged Steel Gate Valve

    1. Forged Steel Gate Valve

    A forged steel gate valve is an isolation valve ideal for opening and shutting media flow in pipelines that handle different media properties, such as gas, neutral liquids, potable water, and wastewater. Since it is made from forged steel, it can handle different pressures and temperatures even with continued use.

    A forged gate valve is a multi-turn valve, meaning the operation of this valve is slow as it requires multiple turns to change from an open position to a closed one. This process eliminates the risks of water hammer effects.

    2. Forged Steel Globe Valve

    A forged steel globe valve is a type of linear motion valve used to open, shut, and throttle media flow. Due to its added strength and high tolerance to varying temperatures, it is used to control media flow in industries that handle severe conditions. These include fuel oil systems, cooling water systems, chemical feed systems, boilers, and more.

    A forged globe valve is designed with a stem that goes up and down and a disc that moves to the seat perpendicularly during the opening and closing of the valve. This movement produces an annular space between the disc and seat ring that slowly closes as the valve closes. With this feature, a forged globe valve performs excellent throttling needed for controlling the process flow.

    Gate Valve

    3. Forged Steel Ball Valve

    A forged steel ball valve is a type of quarter-turn valve that possesses enhanced strength and high tolerance against severe working environments, such as high pressures and temperatures and toxic media. It is widely used in industrial processing plants, chemical and petrochemical applications, pipelines, and more.

    A forged ball valve has a spherical disc that functions as the opening and closing mechanism of the valve. It has a hollow center or hole that provides full media passage when aligned with the pipelines and complete obstruction when perpendicular to the pipelines. The way this valve operates makes it suitable for providing tight sealing with zero leakage.

    4. Forged Steel Check Valve

    A forged steel check valve is a sturdy non-return valve that only allows the media to flow in one direction. It is strong, compact, and suitable for applications dealing with high pressures and temperatures, such as oil refineries, power generation, LPG and LNG plants, and more.

    A forged check valve is a self-automated valve that depends on the process flow to open and close. The internal disc of the valve allows flow to go through, opening the check valve. When the flow starts to decrease or go to the reversed direction, the valve will gradually close to prevent backflow and contamination.
