Yamatake Valve Positioner AVP100 Digital Valve Controller AVP100-H

OVERVIEW

Smart Valve Postioner 100 Series Model AVP100/102 are microprocessor based current-to-pneumatic valve positioners. The 100 Series receives a DC current signal from control devices and controls the openings of valves. In addition to this basic function, the 100 Series has communication capabilities, automatic configuration program, and self-diagnostics functions that increase productivity and efficiency of plant operation.

FEATURES

1. Easy to use

Auto setup

The auto-setup function is a fully-automatic configuration program which specifies the actuator and adjusts the zero and span of the valve. The program can be turned on simply from the internal button so that adjustments to the valve can be performed quickly.

2. Single model for multiple specifications

The 100 Series’ settings can be changed without replacing any parts. A single model can be modified to suit any application.

• Input range: Configurable to any required range for split range

• Flow characteristic: Linear, EQ%, Quick opening or custom user characteristics

• Actuator type: Single or double acting actuator (optional reversing relay required)

3. Valve diagnostic (Model AVP102 only)

Following parameters can be monitored by HART communicator or Control Valve Maintenance Support System “Valstaff ”.

• Stick Slip

• Cycle Count

• Total Stroke

• Shut-Off Count

• Travel Histogram

• Max. Travel Speed.

4. Positive seating

The positive seating function completely shuts off the valve if the input signal becomes lower than previously set. This in turn enhances the full shut-off capabilities of the valves.

5. Easy maintenance

The electrical circuit section and air circuit section are completely separate, making the maintenance of the air circuit section at the work site easy. An Auto/Manual switch is standard equipment, so it is also easy to check the operation of the valve. (However, it is not available for the double-acting actuator.)
