5. Pressure-Temperature Rating (ASME B16.34 – WCB body)
| Temperature (°C) | Max. Working Pressure (bar) |
|---|---|
| -29 ~ 38 | 16.0 (PN16 rating) |
| 100 | 14.5 |
| 150 | 12.5 |
| 200 | 10.8 |
| 250 | 9.5 |
| 300 | 8.2 |
| 350 | 7.0 |
| 400 | 5.5 |
| 425 | 4.4 |
For PN16 rating, the maximum allowable working pressure at ambient temperature is 16 bar. Stainless steel (CF8M) bodies offer slightly better high-temperature performance.
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 (gate valves not recommended for throttling) |
| Leakage Rate | Metal seated: API 598 allowable (minimal leakage) Soft seated optional: Zero leakage |
| Temperature Range (standard packing) | -29°C ~ +425°C |
| Suitable Media | Water, oil, steam, natural gas, non-corrosive and mildly corrosive media |
| Valve Type | OS&Y wedge gate valve, bi-directional sealing |
| Blow-out Proof Stem | Standard |
7. Electric Actuator Specification (Reference)
As electric actuators vary by brand and control requirements, below is a typical configuration recommendation:
| Parameter | Typical Value |
|---|---|
| Actuator Type | Multi-turn electric actuator |
| Mounting Connection | ISO 5210 or direct connection to stem nut |
| Max. Output Torque / Thrust | Based on valve thrust requirement (DN100 PN16 approx. 2000–3500 N thrust) |
| Power Supply | 380V / 3Ph / 50Hz or 220V / 1Ph |
| Control Type | On-Off or Modulating (4-20mA) |
| Enclosure Protection | IP67 (outdoor type) |
| Explosion Proof (optional) | Ex d IIB T4 (flameproof) |
| Accessories | Limit switches, torque switches, heater, local/remote control |
| Position Indication | Valve open/close indicator (mechanical or electronic) |
Gate valves require multi-turn electric actuators, not quarter-turn types.
8. Key Features
-
OS&Y wedge gate design – Stem movement is visible, allowing easy local indication of valve position
-
Bi-directional sealing – Both sides of the wedge seal simultaneously; equal pressure capability in both directions
-
Blow-out proof stem – Compliant with API 600 for safety
-
Full bore – No flow restriction; ideal for low pressure drop applications
-
Motorized actuation – Enables remote on/off, local operation, and signal feedback for automated systems
-
Wear & high temperature resistant – Hardfaced metal seats; suitable for steam, high-temperature oil, etc.
