— Logic elements are cartridge valves suitable for installation

in blocks or manifolds. They are available in five different

sizes: ND 16 - 25 - 32 - 40 - 50 - 63.

— They are designed to perform complex hydraulic circuits,

using functional compact blocks, with high flow rates and

low pressure drops.

— They are made of a cartridge valve with ISO 7368 / DIN

24342 cavity bore and a control cover (4). The cover

includes the cartridge valves pilot lines; some versions are

designed for the installation of ISO 4401-03 valves, to

realise different control functions (see paragraph 8 for

diagrams and function descriptions). A low leakage version,

obtained inserting a seal into the seat no. 5, is also

available.

— The cartridge valves are composed of a jacket (2), a poppet

(1), and a closing spring (3). The poppet can either be

standard (S) or with a damping nose (D), suitable for a

smooth flow control during the valve opening and closing

phases.

— Two types of cartridge valves are available:

- Q type: used for flow and directional control and as a

check valve.

The areas involved are:

A1 - corresponding to the seat diameter area,

considered as reference area = 1

A3 - corresponding to the jacket internal diameter area.

A2 - corresponding to the difference between A3 - A1

The area ratio A1/A3 is 1/1,66.

The valve opens when the pressure, acting either on area

A1(flow from A to B) or on area A2 (flow from B to A), is

higher than the pressure acting on area A3 (added to the

spring load value).

- P type: used for pressure control.

In this case the areas A1 and A3 are equivalent (area ratio

1:1) and the valve enables the flow direction from A to B

only.

— LCM* are logic elements with spool position monitoring

used for directional control, flow control, piloting and as

check valve. They are certified by TÜV.

Available sizes are ND 16, 25, 32, 40 and 50.

2 - HYDRAULIC FLUIDS

Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. For the use of other kinds of

fluid such as HFA, HFB, HFC, please consult our technical department.

Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.

The fluid must be preserved in its physical and chemical characteristics.

LL = Low leakage version,with seal

between C and B.

8.2 - D cover for directional control and check valve function

Functional diagrams Description

Piloting of the cartridge valve through the X port, available on the mounting surface

or with pipe connection 1/4" BSP.

For ND 40 and ND 50 sizes, the external piloting function can be realised by using

control cover type D, with blanking plate code 1950751 (to be ordered separately).

8.4 - DF1 cover for directional control and check function with double pilot line

The cartridge valve can be simultaneously piloted from X and Z1 lines.

The shuttle valve, integrated in the cover, enables the automatic selection of the pilot line

which has the higher pressure (priority line).

The solenoid valve type DS3-TA must be ordered separately (see catalogue 41 150).

- solenoid valve OFF = A ↔ B intercepted flow

- solenoid valve ON = A ↔ B free flow

11 - MONITORED LOGIC ELEMENTS

Monitored logic elements are made of a cartridge valve with directional function and of a cover with built-in inductive proximity sensor. The PNP

type sensor with closed contact states the condition of A↔B intercepted flow.

WARNING ! These valves must be installed and commissioned by qualified personnel only. Before starting any installation,

commissioning or maintenance, it is mandatory to read the Manual of Use and Maintenance, delivered together with the

valve.

11.1 - TÜV Certiﬁcation

The LCM*-QD4 monitored logic elements were tested on a voluntary basis by TÜV and found to comply with the

applicable requirements of the following standard:

• EN ISO 4413:2012 Hydraulic fluid power – General rules and safety requirements for systems and their components

The components can be considered well tried if they comply the basic safety principles and the well tried safety principles

specified in tables C.1 and C.2 of the EN ISO 13849-2:2013 standard depending on the specific application.

The LCM*-QD4 family can be used in safety related parts of control system in category 1 (or higher) as indicated in the

standard EN ISO 13849-1:2015. Possible applications are:

• EN 20430:2020 standards - Machines for plastics and rubber - Injection presses - Safety requirements

• EN 16092-3:2018 - Machine tool safety - Presses - Part 3: Safety requirements for hydraulic presses

• EN 12622:2014 - Machine tool safety - Hydraulic press brakes

• EN 422:2009 - Machines for rubber and plastic - Safety requirements.

The state of well-tried component is mainly application specific.
