1. The p ressure or temperature limits in the referenced tables and any applicable ASME code limitations should not be exceeded.
2. For example, use the co lumn marked 0-1.4 bar (0-20 psig) for a 0.21-1.0 bar (3-15 psig) pneumatic controller with 1.4 bar (20 psig) supply pressure.
3. For applications with downstream pressure in excess of 196 bar (2845 psig), use 196 bar (2845 psig) for Maximum Shutoff Pressure.
