Industry applications have always been geared towards precision, efficiency and reliability. Although other techniques and procedures are being implemented to some extent, hydraulics continues to play an important role in fast and powerful motion sequences. As a proud partner of Wandfluh, we wanted to share some insight into their valve expertise and how together, Hydraquip and Wandfluh can meet your application needs.
Depending on the load capacity, application and installation location, valves have different performance characteristics. Luckily, Wandfluh has a large product portfolio of valves available based on your needs. Below are a few types of valves and their purposes explained.
- Spool Valves: Spool valves are primarily used to control the direction of movement and to move hydraulic cylinders and motors. To realize a high availability of such a hydraulic circuit, the switching power and possible leakage of the valves must be taken into account when the system is designed. Solenoid spool valves are suitable for machine tools and all types of mobile handling systems.
- Poppet Valves: Poppet valves are used where tight closing functions are essential, like leak-free holding of loads, clamping or gripping. Depending on the execution, the poppet valve spool can be opened or closed with a switching solenoid or by the opposite spring. Poppet valves are used in all branches in different executions.
- Pressure Valves: Practically all hydraulic systems require some form of pressure valve, whether it is to secure the system with a pressure relief valve against overpressure in order to avoid damage, or to supply a part of the hydraulic system by means of a pressure control valve with lower pressure. With a sequence valve, a user can be connected on as soon as an adjusted pressure is reached. Pressure valves are used in all branches and applications in various executions.
- Flow Valves: Flow valves are used to control the amount of oil flow. Throttle valves change the opening cross-section and thereby influence the amount of oil and therefore the speed of the cylinder. Flow control valves in contrast to throttle valves are equipped with additional pressure compensation. Consequently, the adjusted volume flow remains unchanged even in case of a variable load pressure. This leads to a uniform and load-independent movement of a cylinder.
As you can see, we have just scratched the surface of Wandfluh’s valve capabilities. The standard valves are also available in explosion and corrosion protection executions, have a modular design and can be adapted to specific customer requirements with a wide range of options.
