The “E” Type Model 12E Diaphragm Linear Positioner is the most powerful of the diaphragm positioners. The diaphragm’s low friction and sensitive action, a relative long stroke and the constant area of a cylinder enable the “E” Type to handle heavier force positioning applications with accuracy. The 12E force rating is 4,500 inch-lb. degrees (508m-N). They can be mounted using the 3-point mountings pad or integral rabbet style mounting holes in the head.
