American Standard Floating Ball Valve

Definition: American standard floating ball valve is a valve that complies with American standards (such as API, ANSI, ASME). Its floating ball automatically compresses the outlet valve seat through medium pressure to achieve sealing, and is suitable for high pressure, high temperature, and harsh working conditions.


Core features:

Standard specifications: comply with API 607 (fire protection), API 6D (pipeline valves), and ASME B16.34 (pressure temperature rating).

High pressure design: The pressure rating covers Class 150~Class 1500 (up to 42MPa), suitable for high-pressure pipelines such as oil and natural gas.

Reinforced structure: The valve seat adopts metal hard seal or PTFE, and the valve body material is ASTM standard carbon steel/stainless steel, which is corrosion-resistant and erosion resistant;

Safety redundancy: Anti static conductive springs, fire-resistant structures, and anti valve stem blowing designs ensure safety under extreme working conditions.


Typical applications: High pressure and highly corrosive medium transportation systems such as liquefied natural gas (LNG), refining equipment, and offshore platforms.

Application adaptability
  • Application adaptability
    01
    The fluid resistance of the full bore design approaches zero, and the reduced diameter structure can reduce weight by 30%, suitable for pressure levels of Class 150 to Class 1500 (up to 42MPa).
  • 02
    Widely used in petrochemical, natural gas transportation, offshore platforms and other scenarios, especially suitable for cutting control of high-pressure and highly corrosive media.
Security redundancy design
  • Security redundancy design
    01
    Fireproof structure: Compliant with API 607 standard, the valve seat can be burned to form a metal to metal seal in case of fire, preventing medium leakage.
  • 02
    Automatic pressure relief function: When the pressure in the valve chamber rises abnormally, the valve seat retracts and disengages from the ball, releasing pressure to ensure system safety.
Easy operation and maintenance
  • Easy operation and maintenance
    01
    Fast opening and closing can be achieved by rotating 90 °, with a 40% reduction in operating torque compared to traditional valves. It supports multiple driving modes such as manual, pneumatic, and electric.
  • 02
    Modular valve seat and detachable sealing ring design facilitate online maintenance and replacement, reducing downtime costs.
Materials and Manufacturing Standards
  • Materials and Manufacturing Standards
    01
    The valve body and key components are made of ASTM standard stainless steel or carbon steel, which is corrosion-resistant and high-temperature resistant (up to 550 ℃), and complies with American standards such as API 6D and ASME B16.34.
  • 02
    The sealing surface can be selected as metal hard seal (hard alloy) or soft seal (PTFE), suitable for different media (water, oil, acid and alkali, etc.) and temperature conditions.
Structural design optimization
  • Structural design optimization
    01
    Anti blow out valve stem: Adopting an integral T-shaped valve stem structure, combined with reverse sealing design, to prevent the valve stem from coming out when the medium pressure is abnormal.
  • 02
    Anti static and low friction: The static electricity generated by the friction between the ball and the valve seat is eliminated through a spring steel ball static electricity export device, avoiding spark hazards; PTFE lining reduces valve stem wear and lowers operating torque.
Dynamic sealing mechanism
  • Dynamic sealing mechanism
    01
    Adopting a floating sphere structure, the sphere is automatically pressed against the outlet valve seat by the medium pressure, forming a single-sided dynamic seal. The sealing surface fits more tightly, especially suitable for medium and low pressure conditions.
  • 02
    The elastic valve seat design combined with spring preload force can maintain stable sealing even when the medium pressure fluctuates, reducing the risk of leakage.
