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.
Scoring on the APFT is based on gender, age category, number of repetitions performed of the push-up and sit-up, and run time. Score tables are found in Army FM 7-22 and on Department of the Army Form 705, Army Physical Fitness Test Scorecard. The score for each event ranges from 0 to 100 points; a minimum score of 60 in each event is required to pass the test.
