*Note: Threaded end dimensions conform to ASME B1.20.1. Face-to-face dimensions may vary by manufacturer. Please verify before installation.*

5. Main Features

1. Non-Rising Stem Design: The stem does not rise during operation, saving installation space and protecting the stem from external damage.
2. NPT Threaded Connections: Standard tapered pipe threads for leak-proof installation in piping systems.
3. Corrosion Resistance: Stainless steel construction (CF8/CF8M) provides excellent resistance to corrosion.
4. Reliable Sealing: Globe valve design ensures good throttling and shut-off capability with minimal leakage.
5. Anti-Rotation Design: Stem-to-disc connection prevents rotation during closure, protecting sealing surfaces.

6. Installation & Selection Notes

• Thread Sealing: Use appropriate thread sealant (PTFE tape or pipe dope) on male pipe threads during installation.
• Flow Direction: Install with flow direction matching the arrow on the body (typically flow below the seat).
• Wrench Flats: The valve body is equipped with wrench flats for proper installation. Do not use the handwheel as a lever for tightening.
• Special Conditions: For high-temperature steam or thermal oil applications, verify packing material suitability.
