Mainly direction valve directs the flow (usually oil) through the system. Flow is given by hydraulic pumps to direction valve, that further distributes oil medium into the system. The route of the liquid medium i.e. oil, is decided by the position of the spool (GIF example as below). Hydraulic system can function as per the requirements by using different design of spools example, all port lock, P-T connected, A-B-T connected, P-A connected etc. Hence, end user should select the correct type of direction valve to serve studied purpose. Direction hydraulic valves can be selected from variety of sizes. In order to select the direction valve, it is essential to know the oil flow and pressure in the hydraulic system. Different sizes are available by manufacturers like mounting in pipelines, subplate mounting and threaded connection like cartridges. Hydraulic valves are subdivided into three essential categories, hydraulic direction, flow control and direction control valves.

Hydraulic motor is used to transform hydraulic fluid energy into mechanical energy (electrical motor rotating shaft). In order to generate enough torque and rotation of shaft, hydraulic pressure and flow is required. You can use hydraulic motors for many applications, such as winches, crane drives, self-driven cranes, excavators, mixer and agitator drives, roll mills, etc. Uses of hydraulic motors as follows: Rolling mills Concrete mixers Winches Crane drive Manual (self driven) cranes Excavators Agitator drives Hydraulic pump and motors have very similar designs. Therefore, some of the fixed displacement pumps can also be used as hydraulic motors. Different types of hydraulic motors as follows:

We supply two types of hydraulic direction control valves as follows: Solenoid Operated – AC 120/240 V or DC 24/48V Manual Hand Operated Valves In our stock, we use most reputable brands for direction control valves as follow: Yuken Polyhydron Rexroth Parker Hydrocontrol Walvoil What are Hydraulic Direction Control Valves? Mainly direction valve directs the flow (usually oil) through the system. Flow is given by hydraulic pumps to direction valve, that further distributes oil medium into the system. The route of the liquid medium i.e. oil, is decided by the position of the spool (GIF example as below). Hydraulic system can function as per the requirements by using different design of spools example, all port lock, P-T connected, A-B-T connected, P-A connected etc. Hence, end user should select the correct type of direction valve to serve studied purpose. Direction hydraulic valves can be selected from variety of sizes. In order to select the direction valve, it is essential to know the oil flow and pressure in the hydraulic system. Different sizes are available by manufacturers like mounting in pipelines, subplate mounting and threaded connection like cartridges. Hydraulic valves are subdivided into three essential categories, hydraulic direction, flow control and direction control valves. – Directional control valves Hydraulic Check valves Directional spool valves Directional poppet valves – Pressure control valves  – Flow control valves Throttle valves Control valves – Electronic hydraulic valves Servo  valves Proportional valves Every valve operated differently from one another. Like check valve allow free flow in one direction and block flow in other direction. The direction control valves allows pressured oil is either direction, depends upon the spool position. The pressure control valve shift at a certain pressure, the shifting/switching pressure can be adjusted on the valve. By adjusting the bore size or orifice, the flow can be regulated in flow control valve. The servo and proportional valve can be used to execute as a direction, pressure or flow control function.

The power produced by a hydraulic motor is determined by the flow and pressure drop of the motor. The displacement and pressure drop of the motor determines the torque it generates. The power output is thus directly proportional to the speed. The motors range from high speed motors of up to 10,000 rpm to low speed motors with a minimum of 0.5 rpm.The power of hydraulic motors can easily be calculated by the pressure drop and flow of motor. Also, the torque can be calculated by the displacement and pressure drop of the hydraulic motor.Note that low speed hydraulic motors are designed in such a way that large torques are generated at low speeds. High speed motors have better operational characteristics at speeds that are at least higher than 500 rpm.

The power delivered in dynamic machines is due hydraulic pumps and its function is to turn mechanical energy i.e. electrical AC or DC motor into hydraulic energy. This is attained by causing an increased volume intake and reduced volume during delivery.

This system is to make oil cooler by using water as a contact agent. Oil, which is to be cooled is passed into the shell around dense copper tubes, having baffles, that makes oil to pass in a sinuous manner. Oil transfer the heat to water that is flowing through the copper tubes (different internal diameter of tubes are used depending on pressure and flow) having number of paths. This supplement the contact time of oil with water for efficient heat transfer. This type of DynaTech Heat Exchangers gives high efficiency i.e. ΔT (T2-T1). T2= Output Temperature of Oil T1= Input Temperature of Oil     Working Pressure upto 10 bars Water is cooling medium/agent in a shell type DynaTech Heat Exchanger, having various copper tubes. Easily accessible tubes by opening end covers. Copper tubes can easily be accessible (for cleaning, repairing or even replacing) by opening end covers. Cooper tubes, if choked, can be cleaned/replaced in case of leakage in heat exchanger
