Description
Crafted from premium forged steel and certified to API 6D/CE/ISO standards, our Forged Steel Floating Ball Valve is engineered for high-pressure, high-temperature, and critical applications. The floating ball structure ensures bidirectional zero-leakage sealing under medium pressure, making it an ideal solution for fluid control in oil & gas, chemical, and power industries.
Superior Material Performance
Forged Body: ASTM A105/A182 forged steel, 30% higher pressure resistance (PN16-PN420)
Hardened Treatment: Ball surface hardness HRC60+, 50% longer service life
Advanced Sealing System
Bidirectional Zero Leakage: API 598 compliant, PTFE/graphite sealing
Fire-Safe Design: API 607 fire-test certified
Efficient Operation
Low Torque: 40% reduced operating torque, multi-actuation options
Visual Indicator: Clear position marking, optional limit switches
Detailed Cross-Section Diagram of a Flanged Ball Valve Assembly
This technical illustration shows a cross-sectional view of a flanged ball valve assembly, highlighting all critical internal and external components. The diagram clearly labels each part, including the valve body, stem, ball, seats, seals, and handle mechanism. The inset provides an enlarged view of the stem sealing arrangement, offering a closer look at the packing gland and spring elements that ensure a leak-free seal during operation.
Key features include:
-
A full-bore design allowing unrestricted flow.
-
A robust handle mechanism for manual control.
-
Precision-seated ball for reliable sealing and minimal torque.
-
Secure bolted flange connections.
-
Detailed component numbering for easy identification during assembly, maintenance, or replacement.
This image is ideal for engineers, maintenance personnel, or procurement teams seeking a clear understanding of industrial valve construction and operation.
