Accurate valve control via pneumatic actuators is the claim for Spirax Sarco’s PP5, EP5 and ISP5 positioners the latter for hazardous areas. Mounted within the valve/actuator, they’re totally protected, also making the assembly compact.
PP5 is pneumatic/pneumatic; EP5 is the electropneumatic version. There’s an installation kit for the actuator column or yoke to NAMUR standards, and it fits any Spirax Sarco PN5000/6000 actuator.
