Approval Order Statement 
Approval for changes to the specification range for the courses per inch (cpi) and thickness of the ptfe fabric used in the construction of the ptfe sewing cuff used with the masters series valves, as well as approval of two changes intended to offset the increase in the force required for valve rotation (torque) associated with the fabric modification. These proposed changes are for the increase in the diameter of the rotation spring and retainer id and reducing the lower limit of torque from 2. 0 in-oz to 0. 2 in-oz.
