This positioner features a stainless steel (CF3M) enclosure that is flame and explosion-proof, making it suitable for use in hazardous areas. On customer demand, a local control panel can be added to the positioner. For example, the panel may include push buttons to open and close the valve and a switch to switch between local and remote control.
This positioner is typically used for proportional systems because it provides six digital outputs and four inputs, making it highly versatile. It is equipped with an advanced calibration process that, when combined with the regulator, ensures fast and reliable positioning of actuators. This results in optimal performance and precision for your system.
The positioner is compatible with all types of actuators, including hydraulic, pneumatic, or electro-hydraulic, as well as spring return, double-acting, and stepping actuators.

MTControl
When the IHP24-AF model is installed in a hazardous Area, opening the Exd enclosure is not allowed.
The MT Pen can operate the IHP24-AF through the enclosure and the MT Control function locks Automatically after operation to ensure unattended use.
The MTControl eliminates the need to open the units Ex D enclosure to operate the push buttons. The magnetic sensors placed below the push buttons, will detect magnetic signals from the MTControl pen provided by Val Controls.
