  1. 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.
  1. 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.

Remark: This data sheet applies to standard PN16 threaded end valves. For special working conditions, please consult the manufacturer.
