The handle operated forged steel top inlet ball valve for simplified maintenance provides an easy to maintain solution for flow control in medium and high pressure systems. Its top inlet configuration allows technicians to access internal components such as balls, valve seats, and seals without disassembling the valve from the pipeline. This greatly reduces downtime during maintenance or inspection.
The valve is manually operated through a handle, providing intuitive control and quick response through a 90 degree rotation. The forged steel body and precision machined internal components ensure tight sealing and consistent flow control. This design includes a split body that allows for modular structure and flexibility in actuator installation, making it particularly useful when customized automation settings are required.
● Top-Entry Structure: Enables direct access to internal components for online maintenance, inspection, or replacement without the need to remove valves from the system.
● Manual Handle Operation: With a simple 90 degree rotation, it achieves rapid and precise control response, making it an ideal choice for on-site adjustments.
● Split Body & Customizable Bonnet: Supports flexible installation of actuators or transmissions without the need for additional brackets.

Q: What is the main advantage of a top-entry valve design?
A: The top-entry design allows for maintenance or part replacement without removing the valve from the pipeline—ideal for critical systems where downtime must be minimized.
Q: Is it compliant with any specific industry standards?
A: Yes, it follows API 6D/6A and ASME B16.10 design standards, including features like firesafe design, O-ring sealing, and DBB capability.
Our handle operated forged steel top inlet ball valve was manufactured with maintenance in mind. The top entrance structure and modular design make maintenance simple and minimize interruptions during inspections or repairs. This valve features DBB, self dumping seat, and fire integrity, providing reliable control and safety with each rotation. For teams seeking performance and practicality in pipeline operations, this is an ideal solution.
