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.
APFT Promotion Points Authorized. Soldiers recommended for SGT can get a maximum of 160 promotion points. Soldiers recommended for SSG can get a maximum of 100 promotion points. The minimum promotion points for passing scores are as follows: SGT â 40, and SSG â 15. The Army Physical Fitness Test (APFT) is based on a 300 point scale. There are 3 different events involved in the APFT. These include a 2 mile run, 2 minutes of push ups, and 2 minutes of situps. Each of these events is worth 100 points. A passing score is a 180, with a minimum of 60 points in each event. To qualify for APFT promotion points, the soldier must achieve the minimum passing score. Soldiers are not eligible for promotion without a passing APFT score.
