About us


The first Iranian manufacture of: 1- Steam line instruments. 2- Liquid level controllers. 3- Control valves.


Azarsam instrument Co. (commercial name as Eyvaz ), was constituted by Ghaffar Shabani in 1993 and has been a pioneer Iranian manufacture of control valves, level controllers, and steam line automatic control equipment. Gradually, we are developing our technology and technical infrastructure investment as well as our production capacity, both for the quality of enterprising and full of initial purposes and take a crucial step toward our country’s self-sufficiency in producing the equipment. Our company has employed more than 100 people and owns an overall amount of 1000 square meters of land. We have commercial co-operation with Afghanistan, China, Iraq, Syria and Turkey. We are planning to accelerate our scope of activities and views to become one of the most famous companies in the Middle East.
