Middle East Oil Valve Project: Supplied 200 sets of explosion-proof actuators for a large-scale oil valve project in Iraq. The desert environment with high corrosion (salt spray, hydrogen sulfide) and high temperature required high protection levels. Our C5-M grade anti-corrosion coating and double-sealed wiring technology ensured long-term operation in open-air sulfur-containing environments.
