Valve positioners are essential components in accurately controlling regulating valves. There are different types of valve positioners available that cater to specific industrial requirements. Here are some commonly used valve positioners:
The reference variable for this type of valve positioner is the standard pneumatic signal ranging from 0.2 to 1 bar. Its accuracy makes it suitable for regulating various pneumatic valves with precision.
For industrial applications that require high-precision control, the electric/gas valve positioner is the go-to option. It accepts an input control signal ranging from 4 to 20 mA.
This type of valve positioner is integrated into the electric actuator, which provides a built-in control algorithm and stable performance. It is suitable for long-term stable operations.
The high air capacity of this device allows for efficient usage in a variety of applications. Additionally, it offers simple attachment to all common linear and rotary actuators such as SAMSON direct attachment and NAMUR rib. It can also be attached to rod-type yokes according to IEC 60534-6-1, or based on VDI/VDE 3847 and 3845 standards.
This positioner is equipped with non-contact position sensing technology and has a plain-text display that complies with NAMUR Recommendation NE 107. It also includes integrated diagnostic functions and has a simple one-knob, menu-driven operation. The LCD display is easy to read in any mounting position, thanks to the selectable reading direction feature.
Moreover, this device is configurable with a computer via the SSP interface, using the TROVIS-VIEW software. It also has a variable, automatic start-up with four different initialization modes. In case of emergency, the sub (substitution) initialization mode allows the positioner to be started up without changing the valve position.
Additionally, all parameters are saved in non-volatile EEPROM and the two-wire system has a small electrical load of 465 Ω. The adjustable tight-closing function and continuous zero monitoring add to the versatility and efficiency of this positioner.
