Description
Based on the search results, a "directly controlled hydraulic slide valve with position sensing" is a high-precision component widely used in industrial automation. This type of valve is also commonly referred to as a direct-operated proportional directional valve with electrical position feedback.🔧 Core Technology: How It WorksThe defining feature of these valves is an internal closed-loop control system that ensures precise and reliable operation.Direct Operation: An electrical signal directly actuates the valve spool (slide) without the need for a separate pilot stage, allowing for fast response times.Position Sensing & Feedback: An inductive position transducer (LVDT) or similar sensor continuously monitors the spool's actual position. This information is fed back to an electronic controller to achieve high accuracy.🏭 Product Examples & ApplicationsSeveral manufacturers offer valves with these features, each tailored for specific applications.Bosch Rexroth 4WRPH6: This is a high-response valve with external piston position feedback and external electronics, designed for applications requiring servo quality performance and quick response times.Bosch Rexroth 4WRPEH: A direct-operated valve with electrical position feedback and integrated electronics (OBE). These valves are used in industrial hydraulic systems for precise control.Duplomatic DSE5J: A direct-operated proportional directional valve with on-board electronics and position feedback, used to control the position and speed of hydraulic actuators.Moog D92x Series: These servo-proportional valves utilize position sensing to convert an electrical input signal into a spool position, which is then used to control hydraulic flow. The D926 and D927 are part of this series.📊 Key Technical SpecificationsWhile exact specifications vary by model, here are common parameters based on the search results:Operation: Direct-operated with electrical position feedback and inte
