#### Abstract

It is a quite quality concerning to control temperature of single crystalline it does when you get most of heat treating Products. It is also important control temperature when you make the A1203(single crystalline) used to jewels, 91ass of watches. heat resistant transparent 91asses. Thus, it is a md to get the proper temperature in accordance with the time process while making mixture of oxygen and hydrogen to have the right temperature. In we will study of electrical valve positioning system for the gas mixture to im quality of Products.
