Electric Globe Valve (Including Actuator)
Electric Globe Valve, KJ961Y‑P54, 200 V, DN32, based on Harbin’s own naming conventions and the construction of similar high‑pressure electric globe valves used in power‑station service.
Specifications:
- Model: KJ961Y‑P54
- Type: Electric‑actuated globe valve (straight‑through pattern)
- Nominal Diameter (DN): 32 mm (1¼”)
- Pressure Rating: P54 in Harbin’s code typically denotes 5.4 MPa (≈ 54 bar) design pressure for high‑pressure steam/water service
- Body Type: Forged or cast steel, bolted bonnet
- Connection: Butt‑weld or flanged (often butt‑weld for high‑pressure station valves)
- Medium: Superheated steam, feedwater, or other high‑pressure fluids
- Temperature Range: Up to ~450 °C (depending on trim and packing)
- Actuator: Multi‑turn electric actuator, 200 V AC supply, with integral gear reduction and limit/torque switches
- Operation: On/Off or modulating control, rising stem, metal‑to‑metal seating
- Design Standards: GB/T 12235 (globe valves), JB/T 3595 (electric actuators), API 602/623 equivalents for high‑pressure service
- Brand : HARBIN ELECTRIC VALVE
Material List:
| Component | Likely Material (High‑Pressure Service) |
|---|---|
| Body & Bonnet | WCB (carbon steel) or 12CrMoV alloy steel |
| Disc/Plug | Stainless steel (SS410, SS304) with Stellite overlay |
| Seat Ring | Integral or welded‑in stainless steel, Stellite‑faced |
| Stem | Stainless steel (2Cr13, SS304) |
| Packing | Flexible graphite (high‑temp) |
| Gasket | Stainless steel + graphite spiral wound |
| Fasteners | Alloy steel (35CrMo) |
| Actuator Casing | Cast aluminum alloy |
| Actuator Drive | Alloy steel gearing |
Functional Notes:
- Designed for power‑station duty where high pressure and temperature demand robust sealing and wear resistance.
- Electric actuator allows remote operation and integration into DCS/PLC systems.
- Rising stem design provides clear visual indication of valve position.
- Stellite hardfacing on seat/disc ensures long service life under erosive steam conditions.
