Benefits
- High reliability and product lifetime thanks to robust enclosures and modular design
- Easy mounting, wiring and calibration for all common types of valves
- Intelligent diagnostic features (Partial Stroke Test, Fail-in-Place function, Valve Signature, Integrated Pressure Sensors …) for higher plant availability and process security
- Up to 95% lower operating costs due to extreme minimal compressed air consumption
Air Torque pneu actuator with SIEMENS SIPART PS2 postioner
Ing Westad AS stocks Air Torque Pneu Actuator with Siemens Sipart PS2 Positioner, as well as manual override, which together form a complete unit for actuation and control of AMOT´s ACV or other valve that must be turned 0-90 degrees.
The double-acting rack and pinion actuator enables the best control of valves that are not ON/OFF, but must be regulated. Siemens Siepart can be controlled by AMOT´s 8071D and 8072E PIDs. The control signal is 4 - 20 mA IN and OUT. Beyond that, only supply air is needed.It is the standard version we stock, many other configurations can be obtained. Further information follows below.
The SIPART PS2 is the most widely used valve positioner for linear and part-turn actuators in industrial applications. The all-round positioner of Siemens provides an extensive range of functions and is well equipped - even for extreme ambient conditions. The following enclosure options are available: Polycarbonate, Aluminum, Stainless steel, Flameproof aluminum or 316L stainless steel.
SIPART PS2 positioners excel in their:
- Easy installation
- Automatic commissioning
- Simple operation and on-device configuration with local display or via SIMATIC PDM
- Very high control performance
- Minimal air consumption in stationary operation
- "Close tight" function for maximum torque on the process valve seat
- "Fast Open/Fast Close" for defined approach of the end position with fast reaction to new setpoint specifications
- "Fail Safe" function: Secure depressurization SIL 2 in case of failure of electrical auxiliary power
- "Fail in place" function: Maintain current position on failure of electrical and/or pneumatic auxiliary power
"Fail to Open" function: Pressurizing of the actuator in case of failure of electrical auxiliary power
Numerous functions can be activated by simple configuring (e.g. characteristic curves and limits)
- One device variant for all applications: Linear actuators, part-turn actuators and cylinders
- Optional with internal or external contactless position feedback for external ambient conditions
- "Intelligent solenoid valve": Solenoid valve function and diagnostics in one device
Extensive diagnostic functions:
- Full Stroke Test
- Multi Step Response Test
- Valve Performance Test
- Valve Signature, pressure sensor-aided
- Partial Stroke Test, optionally pressure sensor-supported for performance and maintenance assessment of the valve
- Leakage monitoring
- Can be operated with natural gas, carbon dioxide, nitrogen or noble gases
- Custom designs for SIPART PS2
- Custom and special functionalities are available after consultation.
