Standard Practice for Selection of Valve Operators

ABSTRACT
This practice provides guidance in the selection of manual and power-actuated valve operators. The selection criteria for manual valve operators apply to handwheels and tee-wrenches. The selection criteria for power-actuated valve operators, on the other hand, apply to stem nut and handwheel driven valve operators of the electric, pneumatic, and hydraulic types.
SCOPE
1.1 This practice provides guidance in the selection of manual and power-actuated valve operators.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
