IMPORTANT! valves mounted with electricactuators should be cycled tothe mid-stroke position beforecycling under ! valves SHOULD NEVER BE USED AS A STRUCTURAL ! valves must be installedwith the FLOW ARROW pointing from highto low pressurewith the VALVE inthe closedisolatingposition. Alternatively the high-pressure end will high-pressure endis defined as the end with the highest pressure,with the VALVE inthe closed isolating :Uni-directionalvalves should not be installed in lines where a differen-tial back pressure (from low to high pressure) of 200 psi or more 7 Localized Stress Relief is acceptable.
