5. Pressure-Temperature Rating (ASME B16.34 – CF8 body, Material Group 2.1)
| Temperature (°C) | Max. Working Pressure (bar) | Remarks |
|---|---|---|
| -29 ~ 38 | 16.0 (PN16 rating) | Ambient |
| 100 | 12.0 | |
| 150 | 9.8 | |
| 200 | 8.1 | |
| 250 | 6.6 | |
| 300 | 5.2 | |
| 350 | 4.2 | |
| 400 | 3.2 | |
| 425 | 2.5 |
Note: CF8 (304) has lower high-temperature strength than CF8M (316). The maximum continuous operating temperature for PTFE seats is approximately 150°C. For higher temperatures, PEEK or metal seats must be selected. The pressure ratings above are based on the body material; actual service temperature is limited by the seat material.
6. Performance Data
| Parameter | Value |
|---|---|
| Pressure Rating | PN16 (16 bar @ 38°C) |
| Shell Test Pressure (water) | 24 bar |
| High-Pressure Seat Test (water) | 17.6 bar |
| Low-Pressure Air Seat Test | 6 bar |
| Allowable Differential Pressure | Full rated pressure (floating ball design requires verification at high ΔP) |
| Leakage Rate | Zero leakage (ISO 5208 Rate A / API 598 Rate A) |
| Temperature Range (PTFE seat) | -29°C ~ +150°C |
| Temperature Range (PEEK seat) | -29°C ~ +250°C |
| Suitable Media | Water, oil, gas, mild acids/bases, solvents (avoid high chloride environments) |

| Flange Facing | RF (Raised Face) standard smoothness |
7. Key Features
-
2-piece body – Easy inline maintenance; seats and seals can be replaced individually
-
Floating ball design – Ball is supported by seats on both ends; medium pressure pushes the ball against the downstream seat for tight shut-off
-
Full bore – No flow restriction; ideal for low pressure drop applications
-
Bi-directional sealing – PTFE seats provide zero leakage shut-off
-
CF8 stainless steel body – Good corrosion resistance for media compatible with 304 stainless steel
-
Anti-static device (optional) – Prevents electrostatic charge accumulation
-
Fire safe design (optional) – Compliant with API 607
8. Actuation Options
| Actuation Type | Remarks |
|---|---|
| Lever + limit stop | Suitable for manual operation of DN100; moderate torque |
| Worm gear operator | For frequent operation or higher torque requirements |
| Electric actuator | On-off or modulating (4-20mA); direct mounting on ISO 5211 top flange |
| Pneumatic actuator | Double-acting or spring-return; with solenoid valve and limit switches |
