Explosion Proof Electric Butterfly Valve

The Explosion Proof Electric Butterfly Valve is a safety-focused flow control device designed for hazardous environments (such as flammable gas, vapor or dust atmospheres). It combines a triple eccentric butterfly valve (with excellent sealing performance) and an explosion-proof electric actuator (certified to meet explosion protection standards like ExdIIBT4), making it suitable for industries including petrochemical, coal chemical, and pharmaceutical production where explosion risks exist. This valve integrates electric control with precise flow regulation: the electric actuator drives the valve disc to rotate (0-90°) to open/close or modulate fluid flow, while the explosion-proof enclosure prevents internal electrical sparks from igniting external hazardous media. It is widely used to control media such as water, liquids, gas, oil, powder, steam, and acid-base corrosive substances.

It is widely used to control media such as water, liquids, gas, oil, powder, steam, and acid-base corrosive substances.

二、Product Features

  1. Explosion-Proof Safety Performance

    Equipped with an explosion-proof electric actuator (compliant with industrial explosion-proof standards), it effectively isolates electrical components from hazardous environments, eliminating ignition risks and ensuring safe operation in flammable/explosive areas.

  2. Excellent Sealing & Corrosion Resistance

    Adopts triple eccentric structure and stainless steel + PTFE seat material, achieving tight sealing (zero leakage under rated pressure) and strong resistance to corrosion from acid-base media; valve body/disc materials (cast iron, carbon steel, stainless steel) can be selected according to media characteristics.

  3. Wide Application Range

    Suitable for multiple media (water, gas, oil, steam, corrosive substances) and applicable pressure grades (PN1.0-PN6.3MPa), with nominal sizes covering DN50-DN1000 to match different pipeline specifications.

  4. Convenient Installation & Operation

    Uses flanged connection type for quick and stable installation in pipelines; electric control enables remote operation, reducing on-site manual intervention and improving automation efficiency.
