Description

The SP400 is a loop powered digital valve positioner for linear and

quarter-turn pneumatic valves. It has been designed for users that

want the benefits of a smart digital positioner but do not need all

the functionality and extra features of the SP500.

Precise control is maintained through valve position feedback that

automatically varies the pneumatic output pressure to overcome

the effects of stem friction and flow forces to maintain

the desired valve position. Indication of valve position is provided

through a continuous digital display of % travel.

The pneumatics are based on piezo-valve technology giving high

resolution, high reliability, vibration insensitivity and class-leading

low air consumption.

The SP400 includes straightforward functionality that can be easily

set up through the screen and keypad. The absence of mechanical

linkages greatly reduces the time required for the mounting

procedure and the software has been designed to simplify

operations as much as possible: commissioning requires just

assembling the SP400 to the valve and pressing one button.

The SP400 is supplied with a NAMUR standard mounting kit for

attachment to yoke or pillar mounted actuators. For quarter-turn

valves, a mounting kit compliant to VDI / VDE 3845 is supplied.

Air supply

The SP400 smart positioner must be provided with a high

quality air supply. A Spirax Sarco MPC2 filter regulator with

coalescing filter or equivalent must be used. A fixing kit is

available to mount the MPC2 filter regulator onto the actuator.

For further product data regarding the MPC2 see Technical

Information sheet TI-P054-04.

Applications

The SP400 can be used with the following pneumatic actuators:

PN1000 and PN2000 series

PNS3000 and PNS4000 series
