Application Notes

OVERVIEW Logic Elements are multi-purpose devices. These valves, when used with other cartridge

valves, can create a wide variety of circuits for control of pressure, ow, and direction.

Dierential sensing valves

SPRING BIASED, NORMALLY CLOSED, DIFFERENTIAL SENSING VALVES

Spring-biased, normally-closed dierential sensing valves include: CP700-1, HLE10-CPC, HLEA10-CPC, CP701-1, and CP702-1. These valves are normally closed and will modulate based on the spring control pressure, inlet pressure at port 1, and pilot pressure at port 3.

Spring-biased, normally-open, vent-to-close dierential sensing valves include: CP700-3, CP701-3, and CP702-3. These valves are normally open and will modulate based on spring control pressure, outlet pressure at port 1, and pilot pressure at port 3. One application for this valve is to create a high-ow pressure reducing valve when using a small relief valve (like CP208-1), or a proportional relief valve (like PRV08-DAC) as a pilot element.

Application Notes

PRESSURE COMPENSATING, DIFFERENTIAL SENSING VALVES

Pressure compensators oer the circuit designer capability to add pressure compensation to any xed or variable orice. This ensures that ow, and resulting actuator speed, are maintained regardless of system and working pressures. Note that a pressure compensator is required when using Danfoss ICS direct-acting proportional ow controls; see Proportional valve application notes for more information.

Restrictive-type Restrictive-type pressure compensators

Restrictive-type pressure compensator

operation are three-ported valves that work in series with a xed or variable control orice. The pressure compensator is located downstream of the orice and is spring-biased to an open position as shown. The spool “senses” the pressure on either side of the control orice

Control orifice

and will vary it’s restriction in order to maintain a constant pressure dierential

Regulated flow

across the control orice, hence maintaining a constant ow rate.

SUMMARY

Priority-type Priority-type pressure compensators are

Priority-type pressure compensator

operation four-ported valves that work in series with a xed or variable control orice. As with the restrictive-type valves, these valves maintain a constant pressure dierential across the control orice. However, rather than restricting ow when the dierential pressure becomes too high, the priority-type pressure

Control orifice

Regulated flow

compensators open a fourth bypass port for all ow in excess of that demanded

Bypass flow

by the control orice. Note that if the bypass port is blocked, the valve will function as a restrictive-type pressure compensator.

All of these circuits are particularly eective to control high ows while using small (e.g. 8 series) solenoid and relief valves as pilot elements. The above examples are typical circuits but are by no means the only applications for these valves. Eective use of dierential sensing valves is a key to designing cost-eective circuits, and is limited only by the imagination of the designer.

Logic Elements Technical Information

Spool Type HLE10-CPC

OPERATION

The HLE10-CPC is a 10-size, high pressure, normally-closed, pilot-toclose, spool-type, spring biased dierential-sensing logic element. It will modulate ow from 1 to 2 based on the spring control pressure, inlet pressure at port 1, and pilot pressure at port 3.

APPLICATION

Common applications include load-sensing bypass compensator for a xed displacement pump with single or multiple actuators as well as bypass-type pressure-compensated ow control. Eective use of logic elements is a key to designing cost-eective circuits, and is limited only by the imagination of the designer
