How to order

Please include all the required optional extras as described on the first page.

Example: 1 off Spirax Sarco SP500 0R00000G4 electropneumatic smart positioner equipped with retransmission and software

switches board plus gauge block for full scale pressure of 4 bar.

Caution: The SP500 smart positioner must have a high quality air supply. A Spirax Sarco MPC2 filter regulator with coalescing filter

or equivalent must be used inclusive of fixing kit - See Technical Information sheet TI-P054-04 for further data and How to order.
