Intelligent Hydraulic Positioner - Basic Flameproof

Flameproof positioner for critical valve systems

Introducing our positioner in an Ex d enclosure - the ideal solution for achieving precise positioning of actuators or choke valves with solenoid valves. Our Stainless steel (CF3M) flame and explosion proof enclosure provides maximum safety for critical controls in hazardous areas, yet still with access to the user-friendly interface.

Our positioner is equipped with an advanced calibration process that, when combined with the regulator, ensures fast and reliable positioning of actuators, providing an optimal performance and precision for your system.

The positioner is compatible with all actuator types including; hydraulic, pneumatic, or electro-hydraulic - spring return, double acting and stepping actuators, making it a versatile solution that can easily adapt to your system's needs.

Horizontal and vertical enclosure options

The IHP24-BF is available in a horizontal and vertical enclosure option to fit the end-user's valve system for easy mounting. The stainless steel box fits a terminal strip for the electrical connections.

These options provide the same features as the base model without the added stainless steel box.

Local user interface

On the local user interface, you can see the status of the valve system, check error messages, start auto calibration, and configure the positioner. The USB port provides easy access to configure the positioner on a PC using ValConnect.

Val Controls provides a magnetic touch pen that gives full access to the local user interface when the valve system is in operation. This eliminates the need to open the Ex D enclosure to operate the push buttons.

The local user interface is fitted with various indication LEDs that display, for example, if valve movement is in progress or if the valve is open or closed.
