4. Main Dimensions & Connection Data (Unit: mm/in)
Note: Nipples ends typically include male NPT threads (ASME B1.20.1) or socket weld ends on both sides for direct connection to pipe.
| Size (NPS) | Nipple End Type (Typical) | Face to Face (End to End) (L) approx. | Center to Top Height (H) approx. | Lever Length (mm) | Ball Bore Dia (Full Port/Reduced) |
|---|---|---|---|---|---|
| 1″ (DN25) | NPT Male Thread (ASME B1.20.1) or Socket Weld | Manufacturer Standard (Typically 150-200 mm) | Varies by design | 150-250 | Approx. 25 mm (Full Port) or Reduced |
Note: Dimensions above are typical. Final dimensions should be based on approved manufacturer drawings.
5. Applicable Design Standards
-
Design & Manufacture: API 608 / ASME B16.34 / ISO 17292
-

6. Product Features
-
Metal Seated Design: Hard-faced seat and ball (Stellite, Tungsten Carbide, or Hard Chrome) provide exceptional wear resistance, high-temperature capability (up to 500°C+), and resistance to abrasive media.
-
3-Piece Construction: Swing-out design allows for easy in-line maintenance; seats, ball, and seals can be replaced without removing the valve body from the pipeline.
-
Nipples End Connection: Factory-installed nipples (threaded or socket weld) provide a compact, ready-to-install solution, eliminating the need for separate pipe nipples and reducing potential leak points.
-
Floating Ball Design: Ball is pressed against the downstream seat under pressure, ensuring tight shut-off; the spring-loaded metal seat ensures consistent contact even under low pressure or thermal cycling.
-
High Temperature Capability: Metal-to-metal sealing allows operation in high-temperature applications where soft seats (PTFE, PEEK) would fail.
-
Blow-out Proof Stem: Stem is designed to be retained within the body even if the gland nut is loosened under pressure.
-
Anti-Static Device: Spring-loaded ball/plunger ensures electrical continuity between ball, stem, and body to prevent static spark build-up.
-
Fire Safe Design: Compliant with API 607, ensuring secondary metal-to-metal sealing in the event of fire damage to primary seals.
Remarks:
-
Material Options: Available in A105 Carbon Steel (for non-corrosive high-temperature services) or F316 Stainless Steel (for corrosive services). Specify material grade when ordering.
-
Seat Material: Confirm required seat hard-facing material based on temperature and media abrasiveness (Stellite, Tungsten Carbide, etc.).
-
Nipple Type: Confirm if NPT threaded or Socket Weld nipples are required.
-
Locking Device: Lockable lever handle is available upon request for safety and security.
-
For specific dimensional data and torque values, please refer to the official certified drawings from the manufacturer.
