Guidelines for Manual Operation of Valves

Pages: 12
Published: 2009

Price: $73.00

The purpose of this Standard Practice is to provide valve users with information for use in evaluating the manual operation of valves. It must be understood that this information is general in nature and must be supplemented by specific operational data for the valve and service
conditions to be experienced. The maximum and minimum torque ratings of specific valve and actuator types are not covered by this Standard
Practice, but must be considered when applying manual input devices to any specific valve. Data from the valve and actuator manufacturers should be consulted regarding valve and actuator types and ratings.
