Petro Sazeh Mihan Company was founded in 2011 by Mr. Rezaei and a professional technical team. Since then, it has steadily grown toward the design and manufacturing of control valves based on local expertise in Iran. The company initially started with industrial valve repair, then moved on to manufacturing relatively simple components. Ultimately, through the use of local knowledge and reverse engineering, these efforts led to the production of control valves with actuators.
The industrial valves manufactured by this company are designed and produced in full compliance with national and international standards, based on precise engineering processes. All products undergo comprehensive quality control tests and technical inspections prior to market release and have successfully obtained معتبر quality and performance certifications.
Obtaining these certifications reflects our commitment to quality, safety, and product reliability, and enables the use of our manufactured valves in critical projects within the oil, gas, petrochemical, power generation, and other heavy industries. Our objective is to deliver products fully aligned with project-specific requirements and to achieve long-term satisfaction of employers and contractors.
