Siemens · Control Valves & Positioners
SIPART PS2 Valve Positioner
Electropneumatic positioner for linear and rotary control valves, with partial stroke testing.
Where it fits
The positioner determines how well a control valve actually tracks its setpoint, and this one self-commissions against the valve rather than requiring manual stroke setup. Partial stroke testing lets a safety shutdown valve be proof-tested without closing it, which is the only practical option on a continuous plant.
