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.
To join the United States Marine Corps as an infantryman or, as that military occupational specialty is known in this branch of service, rifleman, you need a general technical score of 80 on the Armed Services Vocational Aptitude Battery.
Best Answer: 60 percent of Army enlistees have an AFQT score in the Category I-IIIA range, which is: Category I - 93-99 Category II- 65-92 Category IIIA - 50-64 36 percent have: Category IIIB - 31-49 and 4 percent have: Category IVA - 21-30 The highest possible score (it is a percentile, not an overall score) is a 99.t's the AFQT and the GT Score that will let you know what Military Occupation Specality (MOS) you qualify for. You need a 31 on the AFQT to join and a 50 to get any MOS. Also the higher your AFQT the better your bonus will be.
