【Product Overview】

The D941X-2.5C Electric Ventilation Butterfly Valve is a low-pressure, large-diameter valve designed for air, gas, dust, and flue gas control in ventilation and exhaust systems. Built with a carbon steel (WCB) body, soft rubber seat, and electric actuator, it ensures reliable sealing, corrosion resistance, and easy automation.

With a flanged connection and full bore design, this valve is ideal for on/off or modulating control in HVAC, air purification, and energy recovery systems. Rated at low pressure (0.25 MPa), it is optimized for air-tight control in non-liquid gas systems.
