American Standard Flanged Ball Valve

Working principle

The flow of media is controlled by rotating the ball 90°.

A through-hole with the same diameter as the pipe is located in the center of the ball. When the handle or actuator rotates the ball 90° until the through-hole aligns with the pipe axis, the media flows freely without obstruction, the valve is fully open, and the flow resistance is almost zero. When the ball rotates another 90° until the through-hole is perpendicular to the pipe, the solid spherical surface completely blocks the passage, the valve closes, and reliable shut-off is achieved.

The American Standard Flanged Ball Valve adopts a bidirectional sealing design, allowing the media to enter from any direction without flow direction restrictions. Soft seals (PTFE/PPL) achieve zero leakage, while hard seals are suitable for high temperature and high pressure. The valve stem features an anti-blowout structure to ensure safety and reliability under high pressure. Shenchi ASME standard flange ball valves are manufactured strictly according to API 608 standards, offering quick operation and tight sealing, making them ideal shut-off valves for ASME standard pipelines in the oil, chemical, and natural gas industries.

Core Structure and Design Highlights

Shenchi's high-quality American Standard Flanged Ball Valves feature a core structure comprising the valve body, ball, stem, and seat seals. The ball can be either a floating ball design (DN50 and below) or a fixed ball design (DN50 and above). The ball's through-hole matches the pipe's inner diameter, resulting in near-zero flow resistance when fully open. A stem anti-blowout structure prevents the stem from flying out under high pressure. An anti-static device ensures conductivity between the ball and stem, preventing static electricity buildup. For ASME flange ball valves with available quotations, Shenchi provides detailed technical parameter tables to facilitate accurate model selection and budget calculation for customers.
