Forged Steel Gate Valve
A Bolted Bonnet Forged Steel Gate Valve is a robust and durable type of forged steel gate valve designed for high-pressure and high-temperature applications. Its unique construction features a bonnet and body connected by bolts, ensuring a secure and leak-proof seal. These valves are sealed with spiral wound gaskets, making them easy to maintain and ideal for demanding industrial environments.
Our Bolted Bonnet Forged Gate Valves are engineered to meet the needs of small-diameter pipelines, with pressure ratings ranging from Class 150 to 2500 LB. They are capable of operating in temperatures from -29°C to 425°C for carbon steel models and up to 500°C for stainless steel variants. These valves are designed to either shut off or connect the flow of medium in pipelines, making them versatile for a wide range of applications. Depending on the material selected, they can handle various media, including water, steam, oil, nitric acid, acetic acid, oxidizing agents, urea, and more.
Key Design Features
Positive Backseat and High-Quality Packing
The valve features a positive backseat design, high-quality packing materials, and an improved stuffing box design, ensuring a tighter stem seal and enhanced performance.
T-Head Stem Design
The T-head stem provides a secure connection between the disc and stem, ensuring reliable and effective seating operation.
Fully Guided Solid Wedge
The solid wedge design reduces wear on seating surfaces, extending the valve’s lifespan and maintaining consistent performance over time.
Stud and Bolt Arrangement
This design simplifies packing maintenance, making it easier to service and repair the valve without extensive downtime.
Recessed Body-Bonnet Joint
The recessed joint design captures the stainless steel spiral wound gasket, ensuring a leak-proof seal between the body and bonnet.
Rolled-In Seat Design
The rolled-in seat ensures a tight and effective seat assembly, enhancing the valve’s sealing integrity and overall reliability.
Applications and Benefits
Bolted Bonnet Forged Gate Valves are widely used in industries such as oil and gas, petrochemical, power generation, and water treatment. Their robust construction and reliable performance make them suitable for critical applications where safety and efficiency are paramount.
The bolted bonnet design and spiral wound gaskets ensure a secure seal even under high-pressure conditions. This makes the valve easy to maintain and repair, reducing operational costs and downtime. Additionally, the choice of materials, including carbon steel and stainless steel, allows these valves to handle a wide range of media and operating conditions.
A Pressure Sealed Bonnet Forged Steel Gate Valve is a high-performance forged steel gate valve designed for extreme pressure conditions. Its unique construction features a threaded connection between the body and bonnet, sealed by an internal pressure sealing ring. One of its standout advantages is that the sealing performance improves as the internal pressure increases, making it exceptionally reliable in high-pressure environments.
These valves are specifically engineered for high-pressure services, typically exceeding 100 bar. The pressure seal bonnet design ensures that the body-bonnet joint becomes tighter and more secure as the internal pressure rises, providing a leak-proof seal even under the most demanding conditions.
