1) Valve Torque Rating Bray has classified valve torque ratings according to 3 types: non-corrosive lubricating service, general service, and severe service. Torques listed are for general services. Consult Bray for torque information correspond- ing to specific application. 2) These Seating/Unseating Torque values are to be used for all differential pressures up to 150 psi. 3) Dynamic Torque values are not considered. See Technical Bulletin No.1002 for evaluation of Dynamic Torque values vs. Seating/Unseating Torque values. 4) Do not apply a safety factor to above torque values when determining...
