100 24-month Festo Didactic warranty Hydraulics Training Packages > Equipment Sets > Closed-Loop Hydraulics Understanding and setting up hydraulic control loops Hydraulic closed-loop control circuits are normally operated with continuous valves. A control valve with integrated electronics, linear characteristic curve (volumetric flow rate relative to actuating piston position) and zero overlap makes commissioning easy, and provides good results in the closed-loop control circuit. The equipment set for ClosedLoop Hydraulics, TP 511 provides the necessary components. The number and design of the components of the equipment set and the projects of the training media are optimally coordinated. This makes for effortless teaching of the essential basics. Without needing tools and using just one hand, the components can be flexibly arranged on a profile plate with 50 mm slot spacing or in an ER mounting frame to create a wide variety of pneumatic control systems. All hydraulic and electrical connections are on the top of the components so they are easily accessible. The hydraulic connection is made without tools using low-leakage stainless steel couplings. The coupling nipple and coupling socket are self-sealing when uncoupled and are pressure-resistant up to 12 MPa. Sensors for pressure, temperature, and flow can be used at any coupling point. The electrical components have 4 mm safety sockets or M8/M12 industrial connectors. All components are of industrial quality. The components are supplied in practical equipment trays. The equipment trays not only fit in the drawers of the laboratory furniture, but also in a Systainer. Adhesive symbols for clearly labeling where components are stored in the equipment trays are included in the scope of delivery. For the additional task 21 for position control with disturbance variables and active load, the brake cylinder for the linear drive (order no. 152295), which is not included in the scope of delivery, three additional hose lines with quick-release couplings and a shut-off valve (order no. 152844) are required.
