Description
Electric hard seal ball valves are 90-degree rotary valves driven by electric devices, composed of electric actuators and valve bodies. Driven by electric power, the ball core rotates to realize medium cut-off and flow adjustment, adopting flange connection design.
With metal hard seal structure, this valve is well suited for severe working environments featuring high temperature, high pressure, severe abrasion and strong corrosion.

Advantages
Automation
Remote/intelligent control, compatible with PLC/DCS systems, saving manpower;
Fast Response
Switching action completed in 3-5 seconds (some adjustable models can precisely control flow);
Long Lifespan
Sealing surfaces are not easily eroded, hard seals can last for more than 10 years;
Safety
Equipped with anti-static and anti-stem ejection designs, some models have explosion-proof actuators.
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.
Application Scenarios
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.

FAQ
FAQ
Q: What is an electric hard-seal ball valve?
A: It is a 90° rotary ball valve controlled by electricity, composed of an electric actuator and a valve body. The motor drives the ball core to rotate, realizing medium on-off and flow regulation.
Q: What is the connection method of this valve?
A: It adopts a flange connection, which is easy to install, disassemble and maintain in industrial pipelines.
Q: What is the core feature of the hard-seal structure?
A: Its core is a metal-to-metal sealing structure, which has better wear resistance and sealing performance.
Q: Which working conditions is it suitable for?
A: It is specially designed for harsh working conditions, such as high temperature, high pressure, high wear or strong corrosion.
Q: Can it realize automatic control?
A: Yes, it is equipped with an electric actuator, which can realize automatic on-off and flow regulation without manual operation.
