5.1 Mounting the SP200 positioner - General information

Preliminary check of valve and actuator assembly - A preliminary check should be carried

out on the valve and actuator assembly prior to mounting and commissioning the SP200

positioner to confirm smooth movement of the stem. This can be performed by providing an air

supply directly from a filter / regulator to the actuator. The air supply pressure should be

gradually increased to progressively move the stem through its full travel. Any friction or jerky

movement of the stem should be investigated prior to commissioning the SP200.

5.1.1 The SP200 is supplied with a NAMUR standard fixing kit for linear actuators (yoke or

pillar) or with a VDI / VDE 3845 compliant mounting kit for rotary actuators.

5.1.2 Permitted and forbidden mounting positions

The SP200 will not work if mounted on its side or upside down. The positions marked

with an “X” are not allowed. In case this cannot be avoided, please contact Spirax Sarco.

It is possible to ask for a special calibration when you place the order. In this case the

positioner shall be mounted only in the chosen position..

5.1.3 The SP200 has an enclosure rating of IP65 and should be installed in a location that will

not exceed its ambient temperature limits of -10

°C minimum and +80°C maximum.

5.1.4 Before fitting and commissioning the SP200 positioner ensure that the valve and actuator

are correctly assembled. Refer to the valve and actuator Installation and Maintenance

Instructions for details.
