Yuken Product

Product Details:

These valves are composed of a solenoid operated pilot valves and a pilot operated slave valve. When a solenoid is energised the pilot valve directs the flow to move the spool of the slave valve, thus changing the direction of flow in the hydraulic circuit.

Product Details:

Other Detail:

• Spring loaded sealed piston construction. Encapsulated design For protection against dirt. 
• Pressure ranges adjustable up to 40,100,200 & 350 Kgf/cm². 
• Plug-in connector conforming to DIN 43650 / ISO 4400 for electrical connection as Standard feature. Transparent plug-in connector is available with LED.

Product Details:

These valves may be used to shift the direction of oil flow by depressing the spool by way of a cam. 

Product Details:

These Check Valves are flow in one direction and pressure flow in reverse direction, until operated by pilot operated pressure to allow reverse flow. The specific cracking pressure required to open the valve to allow free flow direction.

Product Details:

These check valves allow flow in one direction and prevent flow in the reverse direction, until operated by pilot pressure to allow free reverse flow. The specified cracking pressure is required to open the valve to allow free flow direction

Product Details:

These are Solenoid Operated Directional Valves of No Leak Type developed with the aim of responding the demand of the age including energy saving. Because these valves are of no leak type they allow the low viscosity hydraulic fluids to be used as well as the circuit construction which cannot be used by the conventional spool type directional valves because of too much internal leak of pressure oil. The use of the low viscosity hydraulic fluids reduces the pressure loss which can arise from the pressure resistance of the hydraulic fluids, leading to the system energy saving.

Product Details:

Feature:

• Installation and mounting space can be minimized.
• No special skill is required for assembly. Any addition/alteration to the hydraulic circuit can be made quickly and
• easily.
• Problems such as oil-leaks, vibration and noise which may be caused by piping are minimized, increasing the
• reliability of the hydraulic system.
• Maintenance and system check-ups can be easily carried out as they are normally installed in stackable units.

Product Details:

For hydraulics systems with high flow rates, which 03 series valves (Maximum Flow rate of 70 L/min.) are not capable of handling, 06 series modular valves (may flow rates of 500 L/min.) have been conventionally used. In such cases, the use of 04 series valves for hydraulic systems with flow rates up to 300 L/min. will help to reduce both cost and system size.

Product Details:

The modular valves are functional elements with which a hydraulic system can be built easily by stacking them with the mounting bolts. Therefore, no piping is required for the manufacture of the hydraulic systems. Yuken’s 06 Series Modular Valves are widely used in hydraulic systems for the various industrial and marine equipment including machine tools, special purpose machines, presses, steel mill equipment and ships. The Valves have standardized mounting surface conforming to ISO 4401-AE-08-4-A and optimum thickness for the stacking. 

Product Details:

Other Detail:

• These valves protect the hydraulic system from excessive pressure, and can be used to maintain constant pressure in a hydraulic system.
• Remote control and unloading are permitted by vent circuits.

Product Details:

These valves may be used to manually shift the spool position and change the direction of oil flow

Product Details:

These valves perform a change over of spool by hydraulic pilot and shift the direction of oil flow.

These pumps have been developed especially for low noise operation. To comply with a wide range of applications for instance the injection moulding machine. PV2R Series Single Pumps provide wide range of delivery volume [5.8-237.0 cm3 /rev.] for the pumps. The main internal spare parts of the pumps are built in as cartridge kit. Therefore, the replacement can be easily done by simply changing the cartridges.

Product Details:

These are variable displacement single vane pumps. they come with inbuilt pressure compensator and flow cut off, which in turn gives good power saving. RV20 series pump is widely used in machine tools. 

Product Details:

These double pumps consist of one SVP1 and one SVP2 series single pumps combined in tandem within a single housing and driven by a common shaft. Fluid delivered from the two separate ports can be either supplied to separate or common circuits.

Product Details:

These pumps works as a source of hydraulic power especially for low noise operation. They combine stable performance and robust construction with range of delivery rates.

Product Details:

These valves allow free flow in one direction and prevent flow in the reverse direction. Cracking pressure specified is the pressure required to open the valve and allow free flow. 

Product Details:

These Valves are the combination of flow control valve, a deceleration valve and a check valve and used mainly for controlling rapid traverse and feed cycle in machine tools. Switching from rapid traverse to feed is made by a cam operation and fine feed control is accomplished by dial rotation regardless of pressure and oil temperature variation. Rapid return is free of cam actuation.

Product Details:

These Valves are pressure and temperature compensating type valves and maintain a constant flow rate independent of change in system pressure (load) and temperature (Viscosity of the fluid). They Control flow rate of the hydraulic circuit and eventually control speed of the actuator precisely. Valves with an integral check valve allow a controlled flow and reverse free flow.

Product Details:

These valves are hydraulically damped, direct operated, pressure control valves which can be actuated by internal or external pilot pressure. There are various types of valve including sequence, unloading and low pressure relief valves, all of which are operated by a pressure rise in the circuit, sensed either internally or remotely.

Product Details:

Pressure reducing valves are used to set the pressure of a hydraulic circuit below that of the main circuit. Operation under remote control is also possible by using the remote control port. 

Product Details:

Unloading relief valves are used to operate pumps under a minimum load in accumulator or 2-pressure pump circuits etc.

Product Details:

Yuken’s Logic Valves comprise cartridge type elements and covers with pilot passages. Various types may be combined for direction, flow rate and pressure control. Yuken Logic Valves can be incorporated in manifold blocks to form optimum integrated hydraulic circuits and compact hydraulic power units. Being a poppet type, the elements permit high pressure, high flow rates, high speed and shock less shifting with low pressure drop. Typical applications include steel mill machines, injection molding machines, machine tools and so on. In addition, Yuken Logic Valves cavity specifications confirm to ISO standards.

Product Details:

This valve is used as a remote control valve for pilot operated type pressure control valves

Product Details:

These valves are used for opening/closing oil path by having the poppet valve operated according to electric signal via solenoid. Because these are of poppet type, there is no hydraulic lock and the internal leakage can be greatly reduced.
