Check valve : Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal. Technical terminology : Cracking pressure — Refers to the minimum pressure differential needed between the inlet and outlet of the valve at which the first indication of flow occurs (steady stream of bubbles). Cracking pressure is also known as unseating head (pressure) or opening pressure.

Hydraulic power pack : Some power packs are large, stationary units and others are more portable. They have a hydraulic reservoir, which houses the fluid, regulators that allow users to control the amount of pressure the power pack delivers to a valve, pressure supply lines and relief lines, a pump and a motor to power the pump.A hydraulic power network is a system of interconnected pipes carrying pressurized liquid used to transmit mechanical power from a power source, like a pump, to hydraulic equipment like lifts or motors. The system is analogous to an electrical grid transmitting power from a generating station to end-users. Hydraulic Power Unit Design and Operation. A hydraulic system employs enclosed fluid to transfer energy from one source to another, and subsequently create rotary motion, linear motion, or force. Hydraulic power units apply the pressure that drives motors, cylinders, and other complementary parts of a hydraulic system. Uses of power pack :

Shaft description :  A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. The various members such as pulleys and gears are mounted on it. A is shaft used for : A drive shaft, driveshaft, driving shaft, propeller shaft (prop shaft), or Cardan shaft is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them. There are two types of shaft:  1.Transmission Shaft :  Counter Shaft. The counter shaft lies parallel to the main shaft and is driven by the input shaft through a pinion gear. Output  Shaft . The final component that carries the power out of the   transmission   gearbox and on to the wheels is the output   shaft . 2.Machine Shaft

Yuken hydraulic accessories: Suction Strainer: Pressure Gauge :  Temperature Gauge : Gauge Isolator : Air Blast Type Oil Cooler :  General Information This valve is designed to use when a pump starts to bleed off the air which is enclosed in a suction line or another lines in the system. Instructions: When this valve is used to bleed off the air for pump start, connect inlet port of the valve adjacent as much as possible to the discharge port of the pump. For the purpose of removing the air in the line, install the air bleed valve at the highest point in the overall circuit. In either case, outlet port of the valve must be connected to the tank line and it should be extended under the oil level in the reservoir. Hydraulic Fluids Type of Hydraulic Fluids Petroleum Base Oil : Use R&O (Rust and Oxidation inhibitor) type oils or anti-ware type oils (equivalent to ISO VG-32 & 46).  Synthetic Fluids:

Semiconductor pressure switch : Anyone can easily set the pressure switches.Real time pressure indication the actual pressure is always displayed. It can be easily operated by the pressure switches.High visibility Pressure values can easily be seen even from distant and dark place. Actual pressures setting method can be set by the pressure switches without conscious of notion of a differential pressure.Wide setting range of differential pressure can be adjusted to a large extent. Relay contact output can hook up terminals and the pressure switches in a similar way of wiring mechanical pressure switches.Wiring with a connector is one output type pressure switches have adopted a connector wiring method. Two types of the pressure setting method is either an external setting method or an internal setting method. Two types of the housing A pressure port location can be selected from the two types, bottom and back. The PZA series are renewal analog type semiconductor switch

Yuken Solenoid Coil : A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron. Devices of this kind can be used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas. Purpose of solenoid coil : When the ignition switch is turned on, a small electric current is sent through the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current through the starter motor, which in turn sets the engine in motion. Solenoid coils working : Solenoid is the generic term for a coil of wire used as an electromagnet. It also refers to any device that converts electrical energy to mechanical energy using a solenoid. The device creates a magnetic field from electric current and uses the magnetic field to create linear motion. Needs of solenoid : When the ignition key is turned all the way to the "

Yuken Modular Valves :  Modular Valves are stack type valves, and require no piping. They not only rationalist system build, but they also meet the technical requirements for a variety of hydraulic systems. Stacking systems is a new era in hydraulics. The valves have standardized mounting surface conforming to ISO 4401 and optimum thickness for each size. Any hydraulic circuits can be easily composed by stacking the valves with mounting bolts. The valves can be used widely for hydraulic systems for various industries such as machine tools, special purpose machines, ships and steel mill equipment. Features : 1.Installation and mounting space can be minimized.↚ 2. No special skill is required for assembly and any addition or alteration of the hydraulic circuit can be made quickly and easily. 3. Problems such as oil-leaks, vibration and noise which may be caused by piping are minimized, increasing the reliability of the hydraulic system. 4. Maintenance a

Flow control valve: Flow-control valves control the rate of flow of a fluid through a hydraulic circuit. Flow-control valves accurately limit the fluid volume rate from fixed displacement pump to or from branch circuits. Their function is to provide velocity control of linear actuators, or speed control of rotary actuators. Typical application include regulating cutting tool speeds, spindle speeds, surface grinder speeds, and the travel rate of vertically supported loads moved upward and downward by forklifts, and dump lifts. Flow-control valves also allow one fixed displacement pump to supply two or more branch circuit’s fluid at different flow rates on a priority basis. Typically, fixed displacement pumps are sized to supply maximum system volume flow rate demands. For industrial applications feeding two or more branch circuits from one pressurized manifold source, an oversupply of fluid in any circuit operated by it is virtually assured.
