Description
The Spirax Sarco SP400 Electrical Intelligent Positioner is a loop-powered device capable of driving both linear and 90° rotary pneumatic valves. a 4 - 20mA input signal determines the valve's set-point, and precise control is achieved through valve position feedback, which automatically varies the air output pressure to overcome stem friction and the force of the fluid, and maintains the desired valve position. The valve position is digitally displayed by a continuous travel %, the valve position feedback is obtained by non-contact technology based on the Hall effect, the pneumatic is based on piezoelectric valve technology, therefore, high resolution, high reliability, vibration resistance and very low air consumption in steady state can be guaranteed.
The SP400 includes many intelligent features that can be used to drive software programming with keystrokes and an LCD display of alphabetic data setting menus. There is no mechanical connection between the valve and the positioner, which greatly simplifies the installation process and reduces the time required. And the software has been designed to be as simple as possible to operate: commissioning is simply a matter of fitting the SP400 to the valve and pressing a key.The SP400 is supplied with NAMUR standard mounting kits for yoke or column mounted actuators. For 90° rotating valves, a mounting kit according to VDI/VDE 3845 is available.
air supply
High quality air must be used for the SP400 Smart Positioner. A Spirax Sarco MPC2 filter reducer or equivalent must be used. Mounting brackets can be supplied to mount the MPC2 to the actuator. For more product data on the MPC2, please refer to TI-P054-04.

The SP400 can be applied to the following actuators.
- PN1000 and PN2000 Series
- PNS3000 and PNS4000 Series
- PN9000 Series
additional option
Pressure gauge block: complete connecting block with 2 pressure gauges (supply pressure and pressure to actuator)
