A pneumatic valve positioner is a device that accurately controls various pneumatic regulating valves. The reference variable for this positioner is the standard pneumatic signal of 0.2 to 1 bar. This makes it suitable for precise control over a wide range of pneumatic valves.
For industrial applications requiring high precision control, an electric/gas valve positioner is an ideal solution. It accepts input control signals ranging from 4 to 20 mA. This ensures accurate control over industrial processes that require tight regulation.
The electric/gas valve positioner is especially useful for gas valve control systems. It can help regulate gas flow and ensure that gas supplies are maintained at a stable pressure and volume. This positioner offers reliable performance and precision control for a wide range of industrial applications.
If you require long-term stable operation, then an electric valve positioner might be the right choice for you. This type of positioner is integrated into the electric actuator and comes with a built-in control algorithm. This ensures greater operational stability over time.
The high air capacity positioner has a range of features that make it a useful tool for industrial applications. It can be easily attached to both linear and rotary actuators, and is compatible with several different attachment methods including SAMSON direct attachment and NAMUR rib. Additionally, this positioner can be attached to rod-type yokes according to IEC 60534-6-1 and rotary actuator attachment according to VDI/VDE 3845.
Not only is this positioner easy to attach, it also has several other helpful features. Non-contact position sensing and integrated diagnostic functions allow for easy operation and troubleshooting. The plain-text display with NAMUR Recommendation NE 107 states and messages on the device provide clear status updates.
Operation of the positioner is straightforward with its simple one-knob, menu-driven system. The LCD display is easy to read from any mounting position thanks to selectable reading direction. The positioner is configurable using TROVIS-VIEW software through the SSP interface on a computer.
In addition to these features, the positioner has variable, automatic start-up with four different initialization modes. In case of emergency while the plant is running, the sub (substitution) initialization mode allows the positioner to be started up without having to change the valve position. All parameters are saved in non-volatile EEPROM and the two-wire system has a small electrical load of 465 Ω. Adjustable tight-closing function and continuous zero monitoring complete the set of features that make this positioner a helpful assistant in industrial applications.
