Make two out of one

This is possible by means of this 6/2 way solenoid valve of the TRIES series 300. This series can control the direction of two volume flows and can therefore replace two 3/2 way solenoid valves. According to the size of the system, the savings achieved are considerable. All current circuit symbols are available; special symbols on request. Depending on the operation of the magnets, the valve actuator is moved into the respective operation position. As a screw-in cartridge with the thread M27x2 and M33x2, it is designed for a maximum perating pressure of 210 bar. TRIES valves ar protected against corrosion.

The comprehensive TRIES screw-in valve range is an ideal valve unit block technology base.

Variable design

This 4/3 way solenoid valve of the TRIES series 300 is available as a screw-in cartridge with the screw-in cavity M22x1,5 an M27x2 in accordance with ISO 7789 and has a very variable design. All current switching symbols are possible; special symbols upon request. It is used for controlling the direction of volume flows. The hydraulic piston is moved into the switch position depending on the impact of the durrent on the double-lifting magnet. Both switching functions are carried out electrically by means of one plug. Operating pressure max. 315 bar. TRIES valves are anti-corrosive.

Brand-new possiblities.

This internally pilot operated pressure relieve valve of series 453 is available as screwing-in cartridge with the threads M22x1,5, M27x2 and M33x2, according to ISO 7789. The pressure relieve valve has an additional leakage oil port. Therefore, it is possible to install an actuator in front and behind the valve. The ports 1 an 2 can be operated with maximum pressure. The valves can be characterized by an excellent pressure override. The maximum adjustable operating pressure is 320 bar. The comprehensive screw-in valve range ist available as a catalogue as well as on CD.

Info and help for hydraulic technicians and technical designers.

TRIES now supplies a brand-new CD-ROM, which apart from information on the product range and company profile contains a survey of the entire TRIES valve programme. All data relevant for technicians and technical designers can be intuitively selected and displayed per mouse click. The appropriate order and type code are generated simultaneously at the time of selection. At TRIES, the long-wided procedure of going through catalogues for ordering the correct valves is a thing of the past. Additional functions make it possible to take over DXF data into ones own CAD applications and to print out technical information. The CD-ROM can run under the usual Windows operating systems from Windows 3.1x and is network-appropriate. Free of charge for TRIES customers.

We are heading in the right direction.

2/2 way solenoid valves of the TRIES series 300 are used in order to generate stopper or flow circuits from volume flows in working or control circuits. Three sizes (M20 x 1.5, M22x1.5, M27 x 2) can be supplied in accordance with ISO 7798. Volume rate of flow up to max. 100 l/min. Different circuit symbols and electrical connections for adjustment to individual conditions are available.

maintain a constant oil flow level.

TRIES screw-in cartridges of the series 513 (2-way) and 515 (3-way) regulate variable volume flows and maintain the set constant value level. This level is infinitely variable and can be secured against adjustment. The mode of operation of both valves is identical; efficiency of the 3-way flow control valve is clearly better. There are three models available: M22 x 1,5, M27 x 2 and M33 x 2 (in accordance with ISO 7789). Nominal flow rate up to max. 150 l/min.

Too much is too much.

It is necessary to feed out part of the oil quantities in case of closed hydrostatic drives. This function is reliably carried out by the 3/3 way scavenge valve of the TRIES series 361 and safe performance of the drives is therefore guaranteed. This hydraulically operated, direct-control slide switch is available as a screw-in cartridge M22 x 1,5 in accordance with ISO 7789 for an operating pressure of max. 315 bar. Switching pressure at 15 bar.

Electric proportional pressure relief valve for exact observance of given pressures.

This pressure relief valve of the TRIES series 432 does exactly what it is told. Thanks to its excellent electronic resolution. This valve is available for direct and internal servo-assistance for different flow quantities. It can be provided as a screw-in cartridge with an accommodated cavity M22 x 1.5 (in accordance with ISO 7789) for pressure ranges up to 315 bar. It is also delivered with different electric contacts.

Pump and motor connections, valve unit blocks, distributor blocks, filter housing, cylinder connections should be sealed prior to being transported.

It is very often the case that traditional SAE plastic seals are not fully leakproof and that test oil leaks out. This does not happen with the flange covers of the TRIES series 863.001. They are fully leakproof. These flange covers are available from SAE ½í to 2í and also for 3000 and 6000 psi.

The following information will probably interest thrifty businessmen: these flange covers can be re-used as often as you want.

This is the absolute fact..

Well controlled.

This 3 way flow-control valve from the TRIES series 515.___C with disconnection and screwed thread M27x2 in accordance with ISO 7789 is frequently used for obtaining adjustable, constant volume flows in case of fluctuating pump conveyor flows. Operating pressure max. 320 bar. The constant pump only has to work against the load pressure. The volume rate of flow adjustment is carried out of an adjusting spindle, which is arrested by means of a counter nut. Sealing against unauthorized adjustment is also possible. The volume flow control is put out of action by means of disconnection. The oil flow is distributed following the load distribution.

Capacity in a double pack double check valve.

Performance of the hydraulically pilot operated double check valve of the TRIES series 602 is comparable with two single check valves. It is equipped with 4 operating connections and 2 control connections. The area ratio of pilot piston to check valve seat is 1 : 2.8. The double check valve is predominantly used for leakage-free locking and unlocking of pressurized hydraulic lines, for example in case of lifting and support cylinders, clamping devices etc. The double check valve is available as a screw-in cartridge in accordance with ISO 7789 with the thread M22 x 1.5. TRIES valves are protected against corrosion.

• Series 518, currentless open
• Series 519, currentless closed

Two proportional flow control valves:

They look absolutely identical, these two electrical proportional three-way flow control valves of the TRIES series 518, currentless open and series 519, currentless closed. They work in the reverse sense but with an excellent efficiency in order to obtain controllable, constant volume flows with fluctuating pump conveying flows. The constant pump only has to work against the load pressure. Both valves are available with the screw-in cavity M22 x 1,5 and M27 x 2 in accordance with ISO 7789. Ristrictor choke and pressure balance are integrated into a screw-in valve. A speciality, which not every screw-in valve can offer.
