Explosion-proof Plug Valve
The Explosion-proof Plug Valve is a corrosion-resistant valve designed for hazardous environments (e.g., petroleum, chemical, and natural gas industries), featuring explosion-proof certification (Ex db IIC T6 Gb), stainless steel or alloy construction, and a rotating plug mechanism to ensure rapid shutoff and safe flow control in flammable or explosive atmospheres

Features
- Automatic Control: Driven by electric actuators that receive electrical signals to actuate the valve core, enabling remote operation, automatic start/stop, and system interlock, thus minimizing manual intervention.
- Fast Response: The valve core rotates for regulation (typically within 90°) with rapid action, allowing quick on-off or flow change to adapt to emergency working conditions.
- High Pressure Compatibility: The valve body and core are structurally designed for high pressure resistance, suitable for high-pressure fluid delivery scenarios in the petroleum industry such as well cementing and fracturing (often reaching dozens to 100 MPa).
- Precise Regulation: Fine control via electric actuators ensures stable adjustment of opening degree, achieving accurate flow control and maintaining stable operating parameters.
- Safety and Reliability: Interlockable with pressure sensors, automatically shutting off upon overpressure to reduce risks of high-pressure fluid leakage or equipment damage.
