Directional control valve two-way hydraulic lock YYS10-00/LDPC10

Application of threaded cartridge valves

The biggest feature of threaded cartridge valve is flexible application.

It can be installed separately with a single valve block or a double valve block (valve suppliers can generally provide such valve blocks at the same time)

It is a tubular element.

It can also be installed in the hydraulic motor, hydraulic pump body, or hydraulic cylinder interface, as a control valve.

It can also be fitted into a valve block with a CETOP interface as a vertical stack valve or a transverse sheet assembly valve.

It can also be installed in the control cover plate of the two-way cartridge valve as pilot control.

Finally, it can also be loaded into a dedicated (pure) threaded cartridge valve assembly block of its own design, such as the following three by the author

Or guide the design of the valve block.

Example one. This loop can control a set of one-way hydraulic cylinders, rise at a pre-set speed, and fall by its own weight. Maximum input

Flow up to 70 L/min, output flow 0 to 30 L/min, pressure up to 21Mpa. 7 threaded cartridge valves (Sterling male

Division). Aluminum alloy valve block 135X 135X60mm, with the valve occupying space 245X225X 60mm.

Example two. This loop uses a proportional flow valve and a proportional relief valve to control two sets of one-way hydraulic cylinders, independent or combined

Row, rise at given speed, fall by weight, speed limit, adjustable. Maximum input flow up to 60 L/min with two output streams

The volume is 0 to 22 L/min and the pressure is 21Mpa. 10 threaded cartridge valves, mostly Hydraforce products. Aluminum alloy valve block 140X140X80mm, the valve occupies space 280X230X80mm.

Both examples 1 and 2 are limited to less than 80mm vertically, and the space allowed vertically and horizontally is also extremely limited

Some of its functional requirements are difficult to achieve with ordinary tubular and plate valves
