RE: Motor Operated Valve. The head of the operator is often shown as M inside a square. The limit switches ZSC/ZSO is acceptable under ISA. I have never seen ZSH/ZSL (high and low for a linear valve I suspect) in my industry. If the valve is used for on/off, it usually takes a XV or UV tag name. If the valve is used for regulatory control application, then they would take the normal PV, FV, TV type of designation. I have also seen HV for operator control only valves.
As an Army infantryman, you'll need a combat score of 90, this score being determined by the sum of your ASVAB scores in arithmetic reasoning, coding speed, auto and shop information and mechanical comprehension.
If you are selected for an U.S. Army ROTC scholarship, you are required to: 1  Sign a contract with the Secretary of the Army. If you are 17 years of age when you enroll, your parents or guardian must also sign this contract. 2  Enlist in the U.S. Army Reserve for a period of 8 years. You must be 17 years of age by the time of enrollment in order to sign an enlistment contract. Pursue the academic discipline (if applicable) identified in the letter that notifies you of your selection as a scholarship recipient.
