LFA type logic directional functions control cover

Type LFA Control Cover (Directional functions)

LFA is to control the logic valve on/off, different control cover can realize different fluid pressure.

Features

▶ Valve poppet with or without damping nose

▶ 2 area ratios

▶ 6 different cracking pressures

▶ 4 stroke limitations

▶ Control cover with integrated seat valve

▶ Control cover with integrated shuttle valve

▶ Control cover for set-up of directional spool valves with or without installed shuttle valve

Function:

2-way cartridge valves are elements that have been

designed for a compact block design. The power section

with connections A and B is installed into the control block

in a receiving hole standardized according to ISO 7368 and

closed with a cover. In most cases, the cover is

simultaneously the connection from the control side of the

power section to the pilot control valves. By control with

respective pilot control valves, the power section can be

applied for pressure, directional and throttle functions or a

combination of these functions. Particularly efficient

solutions are realized by adjustment of the size to various

flows of the individual ways of an actuator. The application

of power sections of elements for multiple functions is

very cost-effective.

2-way cartridge valves generally consist of control cover

 and installation kit. The control cover contains the

control bores and optionally a stroke limitation function, a

hydraulically controlled directional seat valve or a shuttle

valve according to the required overall function.

Additionally, electrically operated directional spool or seat

valves can be installed at a control cover. The installation

kit consists of a bushing , ring (only up to NG32),

valve poppet, optionally with damping nose or

without damping nose as well as closing spring.

The function of 2-way cartridge valves is pressure dependent.
