Top Entry Ball Valve Use Double Stage Turbine for Low Torque

Core product positioning

This high-performance ball valve, featuring an upper-mounted valve body structure and integrated with an innovative two-stage turbine transmission system, is specially designed to address the issue of excessive operating torque for valves under large-diameter and high-pressure conditions. This product ensures the convenience of online maintenance while achieving ultra-low operating torque, making it an ideal control device for critical pipelines in industries such as petrochemicals and energy power.

Details of technical specifications

Core design features

1. Innovative two-stage turbine transmission system

Ultra-low operating torque: Through a two-stage precision turbine reduction mechanism, the input torque is significantly amplified, enabling operators to easily open and close large-diameter high-pressure valves with minimal force

Smooth transmission: The turbine mechanism ensures smooth transmission without impact, effectively extending the service life of the valve

Precise positioning: The deceleration effect makes the opening and closing process of the valve easier to control and precisely position

2. Top-mounted valve body structure

Online maintenance: All internal components (ball, valve seat, valve stem) can be assembled, disassembled and maintained through the top opening without removing the valve from the pipeline

Robust structure: The integrated valve body features higher structural integrity and greater resistance to bending stress

Zero leakage design: Special sealing structure is adopted to ensure long-term sealing reliability

3. Modular sealing system

Bidirectional sealing: Advanced valve seat design is adopted to achieve reliable bidirectional sealing

Fire safety: Standard API 607 fire protection design. The soft seal forms a metal-to-metal secondary seal after burning

Multiple options: Materials such as PTFE, PPL, and metal seals can be selected based on the characteristics of the medium

Detailed explanation of performance advantages

Operational performance

Significantly reduce operating force: Large-diameter valves that traditionally required gearboxes or actuators can now be operated manually and easily

Fast response: Optimize the transmission ratio design to maintain a reasonable switching speed while ensuring low operating force

Multiple drive adaptations: It can be perfectly adapted to manual, electric, pneumatic or hydraulic actuators

Maintain advantages

Extremely low maintenance cost: Internal components are easy to replace, significantly reducing downtime and maintenance expenses

Long service life: Optimized force distribution and selection of wear-resistant materials extend the service life of the valve

Online maintenance: Particularly suitable for continuous process flows that cannot be shut down

Safety features

Anti-static design: Ensure a static electricity path between the ball and the valve body

Anti-blowout valve stem: The valve stem adopts a bottom-mounted design to ensure it will not be blown out under abnormal pressure

Fire safety: Complies with strict fire safety standards
