PP6 Pneumatic Positioner
4.4 35
Description The PP6 positioner can control any valve that is actuated by a linear or rotary pneumatic actuator that conforms with NAMUR. It guarantees an exact proportionality between the stroke of the valve and the value of the pneumatic input signal into the positioner. The PP6 has a cast aluminium housing that is also treated for outdoor installation. The unit can be mounted onto pneumatic actuators either rotary 55-90° or linear 20 to 150 mm (0.79 to 5.9 inches). The positioner can be supplied without a mounting kit or with a kit for rotary or linear actuators, the type must be specified when ordering. As standard the PP6 is equipped with two pressure gauges to indicate air pressure command sent to the pneumatic actuator and the air pressure supplied to the positioner. The PP6 is supplied for a pneumatic control signal 0.2 to 1.0 bar (3 to 15 psi g) and for an air supply pressure up to 7 bar (100 psi g). The positioners can be arranged for sequential operation of two or more pneumatic valves in such a way that the stroke of each valve is obtained by a split-range control signal. For example: 0.2 to 0.6 bar and 0.6 to 1.0 bar (3 to 9 psi g and 9 to 15 psi g) in the case of two valves. The PP6 can also be used to reverse the action of the control signal.
