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.
The minimum number of points to be eligible for non-regular retirement at the age of 60 with 20 qualifying years of service is 1,000 (50 points per year) with a corresponding retirement pay equal to 6.94 percent (1,000/360 x 2.5=6.94%) of basic pay or high three average of basic pay.n most cases, Soldiers who have completed 20 years of active service are eligible to receive Retired Pay at the end of their career. The Date of Initial Entry into Military Service (DIEMS) determines which of the three retirement systems a Soldier falls under.
