Electric hard‑seated ball valves are electrically actuated 90‑degree rotary ball valve assemblies, composed of an electric actuator (for switching or modulating control) and a ball valve main body (for fluid shut‑off and flow modulation). Driven by motor power, the ball core executes rotational motion to realise medium cut‑off, opening and flow‑rate adjustment. Flanged ends are adopted for piping connection. Featuring metal‑to‑metal sealing architecture as its core component, this series is engineered for rigorous operating scenarios characterised by high temperature, elevated pressure, heavy abrasion and intense corrosive media.

Advantages
Automation
Supports remote and intelligent operation with full compatibility with PLC and DCS industrial control systems, drastically reducing on-site manpower input.
Fast Response
Full switching cycle finishes within 3‑5 seconds; certain adjustable variants deliver high‑precision flow modulation capability.
Long Lifespan
Sealing contact surfaces feature outstanding anti‑erosion performance. The hard‑sealing configuration delivers a service lifespan exceeding 10 years.
Safety
Integrated with anti-static and anti-ejection stem structures, the valve ensures stable and safe operation under complex working conditions. Select models are fitted with explosion-proof electric actuators for hazardous industrial scenarios.
Features
Compact structure
Fewer parts, smaller size, and lighter weight;
Simple operation
Fully open/close with just a 90° rotation;
Reliable sealing
Soft seals achieve zero leakage, while hard seals are resistant to high temperatures;
Good flowability
Low flow resistance, allowing for almost no loss of medium flow.

Manufacturing Process
Valve Body Machining
Material (carbon steel / stainless steel) casting / forging → Machining (turning, drilling) → Surface treatment (rust prevention, polishing);
Ball/Seat Assembly
Ball grinding + valve seat (soft/hard seal) installation → Sealing performance testing;
Actuator Assembly
Electric actuator (motor + reducer) assembly → Direct connection to the ball valve body → Control logic debugging;
Overall Inspection
Pressure resistance test, leakage test, operating life test → Factory quality inspection.
Maintenance and Care
Daily Inspection
Regularly check the actuator power supply and seals for leaks, and ensure the actuator operates smoothly.
01
Lubrication Maintenance
Add lubricating oil to the valve stem and actuator gears every 3-6 months.
02
Seal Replacement
Replace soft seals (PTFE) every 1-2 years; replace hard seals according to wear.
03
Actuator Maintenance
Avoid humid/dusty environments; explosion-proof models require regular testing of their explosion-proof performance.
04
