Pneumatic (3-15 psi or 0.2-1.0 bar) single-acting valve positioner for linear motion (sliding-stem) control valves. Force-balance principle. The base-model positioner where neither 4-20 mA input nor HART feedback is needed; commonly retro-fitted to manual handwheel valves to give pneumatic remote operation.
