The ASME/API standard ball valve is a track-type ball valve designed and manufactured according to American standards, primarily used for cutting off, distributing, and controlling the flow in fluid control systems. Its core component is a rotatable ball, which opens or closes by rotating around the centerline of the valve body.

Structural Features

Core Structure: Composed of valve body, ball, seat, stem, and actuator, made from cast steel or stainless steel, suitable for high temperature and high-pressure conditions.

‌Sealed Design: The valve seat is made of elastic material to ensure sealing, and the floating ball structure can automatically move with the medium pressure to enhance the sealing effect.‌

Features and Applications

‌Operation Methods: Supports manual, pneumatic, and electric drives with low operation torque and quick response.‌

‌Application Scenarios: Widely used in high-pressure fluid control systems for oil and petrochemical, energy, and other fields, with pressure ratings up to 2500 psi and temperature ranges from -29°C to 550°C.‌

Technical Specifications

Execution Standards: Adheres to specifications such as API 600, API 602, with flange connections following ASME B16.5 standards.

Inspection and Certification: Sealing performance meets API 598 standards; certain products utilize hard alloy sealing surfaces and nitrided valve stems to enhance wear resistance.
