Valve design - Import export

Proportional regulation and control of high flow rates • Frictionless movement; • High flow rates; • Small footprint and size; • Low power consumption; • Pressure-balanced; • High dynamics; This valve combines the advantages of the Spider-μProp technology with the benefits of a pressurebalanced valve. Due to its large orifice, high flow rates are possible. Furthermore, the valve is distinguished by a high reproducibility of the lift-off point. The electrical power consumption lies thereby in the lowest range of the Plate Armature Technology. The compact design of the valve provides a variety of assembly options for different areas of application.

In powered mode, the field strength generated in the solenoid pulls the plunger against the spring tension out of the non-powered position. Solenoids for DC and AC voltage add considerably to the range of technical variants. As the solenoid encompasses the plunger guide tube and the plunger moves in this encapsulated structure, these solenoid valves are called plunger valves.

• Sizes: Ø 7 mm, Ø 15 mm, Ø 21 mm; • Application: Neutral and mildly aggressive liquids, gases and vapors; • direct actuated; • 2-way valves and 3-way valves, NC; Spider valves are allocated to the micro valve category (outside diameter 7 mm). The anchors installed in the micronized valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. As these valves predominantly featuring cartridge connections have an almost frictionless armature movement, they have a capacity of up to 4 billion actuations, depending upon operation mode. Spider valves may also be triggered via so-called pulse width modulation.

• Seat principle, direct actuated; • Frictionless movement Spider µProp-valves are real proportional valves, in which the armature stroke is proportionally defined by the infinitely-variable current applied. The constant ratio between armature stroke and flow rate thus allows variation of the flow rate by way of the applied current. Spider µProp-valves are like Spider on/off valves microvalves The anchors installed in the micro valves have the shape of a disk. In energized status, this so-called flat armature is pulled against the magnetic yoke component group. If the coil is deactivated, the leaf spring joined to the flat armature presses the seal positioned on the spring-armature assembly unit against the valve seat. These quick-acting valves owing to the small mass of the installed armature achieve switching phases in the millisecond range. These valves have a capacity of up to 4 billion actuations, depending upon operation mode.

Their “airless valve shutoff design” greatly reduces air admixture! Ideal for hydraulic lines with larger pressure fluctuations. Locking mechanism to prevent accidental disconnection maintains tight connection even under vibration or impact. Both socket and plug have builtin automatic shutoff valves to prevent fluid spill out when disconnected. Easy to handle.

A single operation makes simultaneous connections for multiple lines that have a variety of different fluids and sizes. A special design minimizes air admixture in fluid lines upon connection. Compared with conventional Multi Cuplas, approximately double flow rates are realized. This could reduce the size of required plates. (Rate of flow increase depends on Cupla sizes.) The MALC type realizes a 2mm axial eccentricity allowance, while the conventional Multi Cupla is only 0.6mm. Special valve design enables connection of socket and plug under dynamic pressure of up to 2MPa. When connected, the distance between the socket plate and the plug plate is designed to be 30mm for all sizes. This means that any size of Cupla can be mounted and used on the same plate. Airless structure valves prevent outflow of fluid and admixture of air into the fluid line.

Eliminates an unpleasant popping noise and a hose whip back motion when Cupla is disconnected. When the Cupla is disconnected, the pressure left in the plug side hose is released gradually without an unpleasant popping noise and a hose whip back motion. Unique design of air purge system enables the residual pressure release quickly and quietly. A unique but simple purge valve design is good for long and repeated use. The function is assured even under a high supply pressure or with a long hose. Note This product is not a check valve to totally stop the air flow.

Simultaneously connects several ports securely in one operation! Greatly reduces changeover time in multiple ports replacement. Handles several ports at once. Simple manual lever action completes easy connection / disconnection. Twostage lever operation prevents Cupla from accidental dropping due to sudden detachment. Comes with lock mechanism to prevent accidental disconnection. Large flow equivalent to that of SP Cupla Type A. Two kinds of plates are available for each size. Automatic shutoff valves in both socket and plug prevent fluid spill out on disconnection. Selfaligned valve design provides safety sealing of individual socket or plug when disconnected.

Simple and secure pushtoconnect type! Big flow rate! Endface seal design. Gives excellent handling touch. Just push the plug into the socket for simple and secure connection. This reduces connection time and improves efficiency. New valve design for low pressure loss to achieve flow rate increase (15% up over the conventional model). Endface seal is achieved when connected. Low connection resistance allows easier connection/disconnection. No seal damage caused by exhausted lubricant is observed and the handling is superior to external Oring design. Available only with steel body. Not suitable for water or oil. Tube Fitter type is available for pushtoconnect operation.

The MALC type realizes a 2mm axial eccentricity allowance, while the conventional Multi Cupla is only 0.6mm. Special valve design enables connection of socket and plug under dynamic pressure of up to 8MPa. When connected, the distance between the socket plate and plug plate is designed to be 30mm for all sizes. This means any size of Cupla can be mounted and used on the same plate.

1.5 ~ 2 Times Higher Flow. High flow type with "airless valve shutoff" design. Compared with Nitto’s conventional 35MPa Cuplas, the flow volume is increased 1.5 to 2 times. *Increase ratio of each flow volume depends on the Cupla size. "Airless valve shutoff" design minimizes spillage volume on disconnection and admixture volume of air on connection. Best suited for hydraulic lines with drastic high pressure pulsation such as in diecasting machines. Pushtoconnect operation and sleeve stopper design preventing accidental disconnection under vibration or impacts enhances workability and safety. Sizes are Rc 3/8, Rc 1/2, Rc 3/4, and Rc 1. *Only the same size of socket and plug can be connected.

Quenched special steel body! Powerful impact resistance, especially against impulses. Valve is designed to suppress pressure loss, particularly suitable for hydraulic applications which need big fluid flow rates. Automatic shutoff valves in both socket and plug prevent fluid spill out on disconnection. Easy to handle. In addition to conventional female thread type, male thread types (male tapered thread, male parallel thread with 30˚ flare, and male parallel thread with 30˚ coneseat) are newly added. Male thread types are designed especially for direct connection to hydraulic power units effectively. Male parallel thread type complies with both metal seal and Oring seal. (In case of Oring seal, Orings available in the market can be used.) Optional HSPDC Cuplas are available for diecasting machine applications with severe pressure variation. The overall length of male thread type is shorter than that of female thread type plus conversion nipple available in the market.
