valsteam control valves -instrumentation -pc25

PC25

An instrument that converts a standard DC signal to a standard pneumatic signal, for the change-over from electrical controllers to pneumatic control valves, or from electrical measuring system to pneumatic controllers. The PC25 is a force balance device, which converts a 4…20 mA input signal into a proportional 3…15 psi (0,2…1 bar) or 6…18 psi (0,4…1,2 bar) output signal, with a respective supply pressure of 1,7 – 5 bar.

valsteam control valves -instrumentation -pi991

PI991

The microprocessor-controlled positioner PI991 is designed to control pneumatic valve actuators and can be operated locally or by means of control systems. The advanced diagnostic can be partially shown on the local LCD of the positioner or fully on a PC or a DCS workstation with a DTM based software (VALcare or Valve Monitor). The positioner is available with different communication protocols. This includes versions with analog setpoint (4 to 20 mA) and superimposed HARTor FoxCom signal; digital with FoxCom protocol, or fieldbus communication according to PROFIBUS-PA and FOUNDATION fieldbus H1 according to IEC 1158-2 based on FISCO. The PI991 also has the capability to control a Partial Stroke Test (PST) that offers operators a tool to identify the trouble-proof function of ESD (Emergency Shut Down) valves.

valsteam control valves -instrumentation -pi998

PI998

The intelligent positioner PI998 is designed to operate pneumatic valve actuators and can be operated from control systems, controllers or PC-based configuration and operation tools such as the FDT/DTMs or VALcare™. The enhanced functionalities of the PI998 Intelligent Valve Positioner enable a significant reduction in commissioning time and reduction of the total installation cost. The new device offers an improved control performance with or without external accessories such as volume boosters for optimal efficiency of your process. The modular design makes maintenance simpler, and advanced technology increases the total lifetime of the device.

valsteam control valves -instrumentation -pe986

PE986

The ADCATrol PE986 positioner requires an input signal of 4÷20 mA for the proportional control actuator. The positioner compares the output signal from a controller with the position feedback and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure.
