·INDUSTRIAL HYDRAULICS

Directional control valves (DCVs) are one of the most fundamental parts of hydraulic and pneumatic systems. DCVs allow fluid flow (hydraulic oil, water or air) into different paths from one or more sources. DCVs will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. The position of the spool restricts or permits flow, thus it controls the fluid flow.

Pressure control valve can protect a system from the damages which is caused by excessive pressure. These valves can do the pressure control of a system an example for this is, using a line relief valve to limit the maximum allowable system pressure. These valves can be seen in hydraulic systems and they can protect the hydraulic system. In order to achieve the pressure control, pressure relief, and pressure regulation must be done. The pressure is developed in a valve because of the restriction of the fluid flow.

Flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Flow control valve also used to regulate the flow rate in a specific portion of a hydraulic circuit. In hydraulic systems, they're used to control the flow rate to motors and cylinders, thereby regulating the speed of those components.

pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

Modular valves are designed to simplify hydraulic systems, to eliminate the use of pipe connections and save to space, time and costs. The modular valves have standardized interfaces ISO 4401, CETOP, NFPA and thickness in accordance with each valve size. The Modular Proportional Valves are used for continuous flow rate control and also for changing the flow direction in case of using a valve with two solenoids.
