The Rosemount 6 x 10 Power Positioners is a floor mounted torque style power positioner. The drive shaft is available as a left hand or right hand assembly.

The standard cam bar produces a straight line relationship. Shaping the cam bar in the field produces other relationships. Standard rotation (as supplied) moves the lever counterclockwise with increased loading pressure. Reverse rotation moves the lever clockwise with increased loading pressure when valve block and angling bar are reversed.

Signal range options include 3 to 15 psi, 0 to 30 psig, or 4-20mA (VP mounted and piped). Repeatability is 1% of full stroke or better. Full stroke time (unloaded) is 5 seconds or less. 10-inch stroke provides 80° rotation. Electrical connections use 16 gauge pigtail leads. Connections available in brass or stainless steel.
