Description
1. Overview of Explosion-Proof Electric Ball Valve
VTON’s explosion-proof electric ball valves combine robust angle travel actuators with durable ball valve bodies to deliver exceptional performance in hazardous environments. Ideal for cutting off or regulating media flow in gas and liquid pipelines, these valves ensure reliable operation under high-pressure and large-diameter conditions.
Key Features:
- Explosion-proof design certified to ExdⅡBT4-BT6 for flammable environments.
- Integrated actuator with 220V power input for easy installation and operation.
- Supports manual operation via clutch handle when unpowered, with automatic reset when powered.
- Wide application range, including high-viscosity and fiber-laden fluids.
