Description

Product Technical Data Sheet

Product Name: Flanged Floating Ball Valve
Model / Size: 2″ – 150LB (RF) / Floating Type

1. General

This product is a straight-through ball valve with flanged ends and a floating ball design. It is suitable for use in petroleum, chemical, natural gas, water treatment, and general industrial pipelines for isolating or connecting media. The valve features bidirectional sealing, low operating torque, and reliable sealing performance.

2. Basic Parameters

Parameter Value
Nominal Size (NPS) 2 inch (DN50)
Pressure Class 150LB (Class 150)
Type Floating Ball Valve
End Connection Flanged (RF – Raised Face)
Applicable Media Water, oil, gas, steam, mildly corrosive media
Temperature Range -29°C to 150°C (depending on seat material)

Item Standard
Design & Manufacture API 608 / ASME B16.34 / GB/T 12237
Flange Dimensions ASME B16.5 Class 150
Face‑to‑Face Dimension ASME B16.10 (typically 178 mm or 203 mm)
Pressure‑Temperature Rating ASME B16.34
Inspection & Testing API 598 / ISO 5208

4. Main Component Materials

No. Part Material (Typical Configuration)
1 Body WCB (Carbon Steel) / CF8 (304 SS) / CF8M (316 SS)
2 Ball Stainless Steel (A105+ENP / 304 / 316)
3 Seat PTFE / RTFE (Reinforced PTFE)
4 Stem Stainless Steel (13Cr / 304 / 316)
5 Packing PTFE / Flexible Graphite
6 Gland Carbon Steel / Stainless Steel
7 Handle Carbon Steel (with plastic coating)
Note: Higher grade materials (e.g., Monel, Hastelloy) available upon request.

5. Dimensions & Weight

Dimension Value
Face‑to‑Face (L) 178 mm (or as per ASME B16.10; some long‑pattern versions may be 203 mm)
Flange OD (D) Approx. 152.4 mm (ASME B16.5 2″ Class 150)
Height (H) Approx. 150 – 180 mm (handle in open position)
Weight Approx. 8.0 – 12.0 kg (varies by body material and wall thickness)

6. Operating Data

Parameter Value
Operation Manual (lever handle) / Optional: Pneumatic actuator / Electric actuator
Pressure Rating Class 150 (1.6 MPa / 2.0 MPa equivalent)
Shell Test Pressure 3.0 MPa (30 bar)
Low Pressure Seat Test 0.6 MPa (6 bar)
High Pressure Seat Test 2.2 MPa (22 bar)

7. Features

  1. Bidirectional Sealing – The floating ball is pressed against the downstream seat by line pressure, providing tight shut‑off with no flow direction restriction.

  2. Fire‑Safe Design (Optional) – Anti‑static design available; fire‑safe configuration with graphite backup seat meets API 607 / API 6FA.

  3. Blow‑out Proof Stem – Stem is inserted from inside the body with a backseat to prevent blowout under sudden pressure surges.

  4. Low Operating Torque – Precisely machined ball and seat offer low friction, quick quarter‑turn operation, and reduced torque.
