Shop All On-Off Explosion Proof Valves

Explosion-proof on-off hydraulic valves are specially designed valves that can operate safely in environments where there's a risk of explosion due to the presence of flammable gases, vapors, liquids, or combustible dust. These valves are built to stringent safety standards like ATEX, IECEx, EAC, CCC, PESO, MA, and cULus, ensuring they meet the necessary requirements for hazardous locations up to Zone 0, including surface and mining operations. By preventing sparks or ignition sources, these valves minimize the risk of accidents in areas where explosive atmospheres may be present, offering reliable performance and safety assurance in challenging industrial environments.
