Application scenarios
Chemical Process Piping Isolation
Used for media shutoff and manual isolation in chemical process piping. The valve body is made of CF8M stainless steel, while the ball and stem are made of Type 316 stainless steel. The full-port design helps provide smooth flow and low pressure drop, and threaded connections facilitate installation.
Textile Processing Equipment Piping Switching
Used for media shutoff and pipeline isolation in production equipment and associated piping in the textile industry. The product is explicitly suitable for the textile industry and offers NPT, BSPT, and BSPP threaded connections. Its full-port design helps maintain smooth flow and low pressure drop.
Auxiliary Pipeline Isolation for Processing Equipment
Used for manual shutoff and isolation of air, water, or other suitable media in processing equipment and associated piping. The two-piece valve body, full-port design, and safety locking handle are suitable for manual field operation.
General-Purpose High-Pressure Fluid Line Shutoff
Used for high-pressure manual shutoff in general-purpose lines handling air, water, oil, and natural gas. The product has a maximum allowable working pressure of 1000 psi WOG, uses threaded connections, and features RPTFE seats with a zero-leakage sealing rating.
Selection points
Full-Port, Low-Pressure-Drop Flow Path
The full-port design and smooth flow path reduce throttling and pressure drop, making it suitable for piping applications where flow retention is important.
Traceable Valve Body Casting Heat Numbers
The two-piece CF8M stainless steel valve body is investment cast and solution annealed. All valve body castings are marked with casting heat numbers for traceability of material batches and quality records.
Multiple Threaded End Connection Standards
Available with NPT, BSPT, and BSPP threaded end connections for compatibility with different piping thread standards.
Blowout-Proof Stem and Adjustable Packing
Features an internally installed blowout-proof stem and adjustable stem packing, providing stem retention protection and packing seal adjustment.
Safety Locking Handle and Optional Oval Handle
Supplied with a stainless steel safety locking handle to help maintain the valve in the set position, with an optional oval handle available.
Installation & maintenance notes
Operating Pressure and Temperature Limits
During installation and operation, site operating temperatures must be maintained within the range of -46°C to 232°C, and the maximum allowable working pressure must not exceed 1000 psi WOG (69 bar).
FAQ
How does the full-port design of the S80 Series threaded ball valve affect flow?
The S80 Series uses a full-port design to provide smooth flow characteristics and minimal pressure drop, ensuring that the flow path through the valve remains unobstructed.
What key points regarding body material and pressure capacity should be considered for this series?
