DN25-PN25-SW Top Entry Floating Ball Valve A

TECHNICAL DATA SHEET

PRODUCT: Top Entry Floating Ball Valve
MODEL / REFERENCE: DN25-PN25-SW
TYPE: One-Piece Body, Full Port, Side-Entry (Top Entry Maintenance)

1.0 PRODUCT DESCRIPTION & APPLICATION
A robust, single-piece body ball valve designed for superior structural integrity in demanding applications. Its unique Top Entry design allows for all internal components (ball, seats, stem) to be serviced or replaced in-line through the top-mounted bonnet, without the need to remove the valve from the pipeline. This eliminates downtime associated with pipe cutting and realignment. Featuring Socket Weld (SW) ends, it ensures a permanent, leak-proof connection ideal for high-vibration or critical services. Commonly used in chemical processing, oil & gas production, LNG, and high-pressure utility systems where reliability and in-line maintenance are key.

2.0 DESIGN & STANDARDS

• Design & Pressure Rating: ASME B16.34, PN25 (Class 150)
• Akhiri Koneksi: Socket Weld (SW) per ASME B16.11
• Tatap Muka: Per manufacturer’s standard or relevant industry norms
• Fire Safe Design: API 607 / ISO 10497 (Optional)
• Anti-Static Device: Per API 608 / ISO 17292 (Standard)
• Blow-Out Proof Stem: Per API 608 (Standard)
• Desain Kursi: Spring-loaded or pressure-energized for bi-directional or unidirectional sealing.

3.0 GENERAL SPECIFICATIONS

4.0 PRESSURE-TEMPERATURE RATINGS

• Pressure-temperature ratings conform to ASME B16.34 for Class 150/Pressure Nominal 25.
• The maximum allowable pressure is dependent on the selected body/trim materials and operating temperature. Consult detailed P-T chart.

5.0 MATERIALS OF CONSTRUCTION (STANDARD)

6.0 KEY DESIGN FEATURES

• Top Entry Design: Enables all internal maintenance in-line, significantly reducing downtime and maintenance costs. The one-piece body offers superior structural strength and minimizes potential leak paths compared to multi-piece designs.
• Socket Weld Ends: Provide a robust, permanent, and high-integrity connection suitable for high-pressure and high-vibration services.
• Bi-Directional Sealing: Spring-loaded seats often provide reliable sealing in both flow directions.
• Blow-Out Proof, Anti-Static Stem: Standard safety features for hazardous services.
• ISO 5211 Mounting Pad: Facilitates easy and direct mounting of pneumatic/electric actuators.

7.0 TESTING & INSPECTION

• Shell Pressure Test: Per API 598 / ISO 5208 at 1.5 x PN (38 bar).
• Uji Kebocoran Kursi: Per API 598 at 1.1 x PN (27.5 bar) with air or water.
• High-Pressure Gas Test (Optional): For critical service verification.
• Material Verification: PMI (Positive Material Identification) on critical components upon request.
• Documentation: Certificate of Compliance (COC) with test records. Mill Test Certificates (MTC 3.1) available.

8.0 INSTALLATION & MAINTENANCE NOTES

• Weld Procedure: The valve MUST be in the fully open position during socket welding to prevent heat damage to internal seals.
• Follow proper socket weld preparation and technique as per ASME B31.3.
• For maintenance, isolate and depressurize the valve. Loosening the bonnet bolts allows access to all internals from above.

9.0 OPTIONS & ACCESSORIES

• Aktuasi: Pneumatic (Double-Acting, Spring-Return), Electric, Hydraulic.
• Gear Operator for high-torque applications.
• Locking Device for handle/lever.
• Stem Extension for insulated lines.
• Cryogenic or High-Temperature Extended Bonnet.
• Fire-Safe Seats & Seals (certified to API 607).
• Drain / Vent Ports on valve body.
• Special Coatings (Internal Epoxy, Xylan, etc.).
