HYDRAULIC POSITIONER

IHP24

Val Controls develops and manufacture Intelligent Electro Hydraulic Positioners. To be used for valve positioning and has an integrated microprocessor with very flexible software, so the positioner fits almost any hydraulic rotary, linear, double acting, spring return and stepping actuator on the market. The IHP range offer several advantages:

 

  • Smart positioner for hydraulic actuators
  • Automatic intelligent calibration
  • Intelligent valve positioning
  • User-friendly menu
  • Flexible and configurable
  • Ultra low power design
  • Configurable by ValConnect software
  • Build in Power unit Controller
  • Compact flame proof (Ex d) version in SS316
  • ATEX, IECEx and UKCA approved
  • HART, Modbus and Foundation Fieldbus

 

The IHP24 range offers the best in performance and user-friendliness, combining these in a very compact enclosure.

HOW DOES IT WORK?

The IHP24 uses Solenoid Operated on/off Valves, SOV, to move the actuator to the requested set point. It has 4 or more outputs to control SOV’s depending on the model. The IHP24 is designed so it can use any solenoid valve on the market. The unit will automatically adapt the regulator to the performance of the complete system, during an automatic calibration. The desired position of the valve is sent to the IHP24 via the 4-20mA control loop or a communication protocol. The actual position is measured by the IHP via a potentiometer or a 4-20mA sensor. The set point and position signal is compared and the actuator is moved to the requested position.

CONTROL

The IHP24 comes as standard with the following control and communication:

- 4-20mA Control loop with HART
- 4-20mA Position feedback

 

Its is possible to add the following communication buses:

- Foundation Fieldbus
- Modbus

POWER

The IHP24 is powered through a 24VDC power supply.

This power supply also feeds the solenoid valves and the sensors.

POSITION FEEDBACK

The IHP24 uses a signal from the actuator/cylinder to know where it is.

The IHP24 accepts the following signal types:

- 4-20mA - 2-wire
- 4-20mA - 4-wire
- 3-wire potentiometer

HYDRAULIC SYSTEM

All our typical designs controls 2 solenoid operated valves, but some of the IHPs can control up to 4 solenoid valves. The positioner is also easily adapted to any already existing control systems or other designs.
