Proportional solenoid valves are a type of solenoid valve that is designed to provide precise and accurate control over the flow of fluid through the valve. Unlike directional solenoid valves, which are binary valves that have only two positions (open or closed), proportional solenoid valves can control the flow rate of fluid at any point between fully open and fully closed.
The intelligent Hydraulic Postioner (IHP24) can use 1-2 4-20mA proportional valves for control of the hydraulic actuator. The IHP24 is designed so it can use any proportional valve on the market. The unit will automatically adapt the regulator to the performance of the complete system, during an automatic calibration.
One of the main advantages of proportional solenoid valves is their ability to provide precise and accurate control over the flow of fluid, which makes them well-suited for applications that require tight control over fluid flow rates. They are also relatively easy to install and operate, and can be integrated into a range of different control systems. Proportional solenoid valves are typically more expensive than directional solenoid valves, and may require more maintenance due to their more complex design and control mechanisms.
