Features

Since the first product of Smart Valve Positioners was released in 1990, Azbil was committed to enhance a series of smart positioner devices as well as their functional line-up as follows:

■700 Series
Communication protocol: HART, FOUNDATION Fieldbus
Double-action pilot (1 output for a single-action actuator)
Integral type

■300 Series
Communication protocol: HART, SFN
Single-action pilot (for a double-action actuator, a reversing relay is added)
Integral type

■200 Series
Communication protocol: HART, SFN
Single-action pilot (for a double-action actuator, a reversing relay is added)
Remote type (the main part of the positioner and the travel detector are separated)

■SVX models
Communication protocol: HART, SFN
Equipped with an integrated double-action reversing relay
Integral type

■Smart ESD Device 700 Series
Communication protocol: HART
Double-action pilot (1 output for a single-action actuator)
Integral type

Details

■700 Series
The local user interface on the front of the device combines an LCD display and push buttons, and can be used in explosive atmospheres. From the front panel the user can execute the automatic adjustment (Auto Setup) program, check equipment status, and display various parameters.
Integration with device management systems can be done using EDDL, DTM, and PLUG-IN Valstaff.
The installed control valve diagnosis algorithm effectively applies data obtained from the embedded pressure sensors for measuring supply air pressure, output air pressure 1, output air pressure 2, and nozzle back pressure.

■300 Series
Equipped with a splash-proof magnetic switch outside of the explosion-proof enclosure on top of the device in order to run the automatic adjustment (Auto Setup) program, manual span adjustment, and so forth.
Integration with device management systems can be done using EDDL, DTM, and PLUG-IN Valstaff.
Comes with a control valve diagnosis algorithm installed.

■200 Series
Each positioner is used by mounting the travel detector on the control valve actuator and the positioner itself on a 2-inch pipe or the like.
The travel detector can be installed where it is subject to acceleration of 10 G, violent 2,000 Hz vibration, and a high ambient temperature of 80°C
Such features help to extend the product’s service life, make maintenance work safer, and enhance workability.
Other features are the same as the 300 Series.

■SVX models
This smart valve positioner is designed especially for rotary valves (butterfly valves, ball valves, etc.). The design is suited for use in combination with actuators for rotary valves, such as rack and pinion actuators and Scotch-York actuators.
Execution of the automatic adjustment (Auto Setup) program, manual span adjustment, and other tasks can be performed using push buttons inside the casing.
Integration with device management systems can be done using EDDL, DTM, and PLUG-IN Valstaff.
Comes with a control valve diagnosis algorithm installed.

■Smart ESD Device 700 Series
Designed for Safety Instrumented System (SIS) use, conforms to IEC 61508 Standards, and is SIL2- or SIL3-certified.
The local user interface on the front of the device combines an LCD display and push buttons that can be used even in an explosive atmosphere. The following operations can be performed from the interface: automatic adjustment (Auto Setup), check of device status, and Partial Stroke Test (PST).
Various input signals (4-20mA, 0-20mA, 0/24VDC) are supported for use with a solenoid valve or for ON/OFF control instead of a solenoid valve.
Integration with device management systems is possible with EDDL, DTM, and PLUG-IN Valstaff. The installed control valve diagnosis algorithm effectively applies data obtained from the embedded pressure sensors to measure supply air pressure, output air pressure 1, output air pressure 2, and nozzle back pressure.
