4. Materials of Construction

5. Cartridge Seat Features & Benefits

De Cartridge Seat design is a key feature of this valve, offering significant advantages over conventional lined or booted seats.

6. Afdichtingsmechanisme

• Primary Seal: Formed by preloaded contact between the precision-machined disc hub and the flatted sealing surfaces of the cartridge seat.
• Secondary Seal: Achieved by an engineered interference fit of the stem through the seat, providing additional sealing integrity around the shaft.

7. Dimensions & Weights (Reference Values – Wafer Type, PN16)

*Note: Dimensions vary by manufacturer. The following are based on industry standards (EN 558 Series 20). Wafer bodies are shorter than lugged bodies. Request certified drawing for exact dimensions. *

*(Note: Body length (L1) is shorter for wafer style; weight is typically 10-15% less than lugged version due to absence of threaded inserts and shorter body.)*

8. Testen

• Shell Test: 1.5 x rated pressure – No visible leakage.
• Seat Test: 1.1 x rated pressure (bi-directional) – Bubble tight shut-off (Rate A).
• Vacuum Test: Suitable for full vacuum service (e.g., 0.08 MPa).

9. Options & Accessories

• Werking: Hand lever (with infinite positioning), Worm Gearbox (with handwheel), Pneumatic Actuator (double-acting or spring return), Electric Actuator.
• Position Indication: Mechanical visual indicator, limit switch boxes, positioners.
• Stem Extension: For buried or insulated lines.
• Anti-Static Device: Per ISO 5211.
• Fire-Safe Design: Optionally available to API 607.

10. Standards & Certifications

11. Installation Notes (Wafer Type)

1. Centering: Wafer valves rely on the pipe flanges for centering. Ensure valve is centered between flanges before tightening bolts.
2. Gaskets: Cartridge seat acts as the gasket between flanges; no additional gaskets are required.
3. Dead-End Service: Not suitable for dead-end service. Wafer valves must be installed between two flanges.
4. Bolt Length: Use longer bolts to pass through both flanges and the valve body.
