Product Description:
Pneumatic Valve Positioner: The standard pneumatic signal of 0.2 to 1 bar is used as the reference variable for accurate control of various pneumatic regulating valves.
Electric/gas Valve Positioner: This positioner accepts input control signals ranging from 4 to 20 mA and is ideal for industrial applications that require high-precision control.
Electric Valve Positioner: This positioner is integrated into the electric actuator, providing a built-in control algorithm and ensuring stable performance. It is particularly suitable for long-term stable operation.
Features:
High Air Capacity
The positioner boasts an impressive high air capacity allowing for efficient and effective functioning.
Simple Attachment
The positioner can be attached to all common linear and rotary actuators, including SAMSON direct attachment, NAMUR rib, attachment to rod-type yokes according to IEC 60534-6-1, attachment according to VDI/VDE 3847, and rotary actuator attachment according to VDI/VDE 3845.
Non-Contact Position Sensing
The positioner utilizes non-contact position sensing for greater accuracy and reliability.
Plain-Text Display
The positioner features a clear plain-text display with NAMUR Recommendation NE 107 states and messages on the device for easy operation and maintenance.
Integrated Diagnostic Functions
The positioner comes with integrated diagnostic functions to ensure efficient performance and easier maintenance.
Simple One-Knob Operation
The positioner can be operated with a simple one-knob, menu-driven interface for easy use.
Easy-to-Read LCD
The positioner's LCD screen is designed for easy readability in any mounting position, thanks to selectable reading direction.
Configurable via Computer
The positioner can be configured via a computer over the SSP interface using the TROVIS-VIEW software for customized use.
Variable Automatic Start-Up
The positioner features variable automatic start-up with four different initialization modes, including a sub (substitution) initialization mode that allows the positioner to be started up in case of emergency without changing the valve position.
Non-Volatile EEPROM Storage
All parameters are saved in non-volatile EEPROM for easy recovery and maintenance.
Two-Wire System
The positioner features a two-wire system with a small electrical load of 465 Ω for efficient use.
Adjustable Tight-Closing Function
The positioner allows for adjustable tight-closing function to ensure greater efficiency in operation and maintenance.
Continuous Zero Monitoring
The positioner features continuous zero monitoring for greater accuracy and reliability in operation and maintenance.
