Logic Elements

Differential pressure sensing elements for applications up to 350 bar (5000 psi) and 400 L/min (100 USgpm)

Get the flexibility to design more efficient, effective hydraulic integrated circuits (HIC) packages with Danfoss logic element hydraulic valves. Designed to provide total control over pressure, flow and direction, logic element valves span a broad range of pressure ratings and applications.

Logic element cartridges have hardened and ground spools, and/or honed sleeves, poppets and sharp-edged ground steel seats, which provides durability, dirt tolerance, reliable seating and fast cycling.

Danfoss cartridge valves and coils can be supplied with zinc plating, and aluminum manifolds can be anodized to improve corrosion resistance.

These cartridges provide the system designer with a versatile range of elements for use in HIC packages for controlling pressure, flow and direction of flow.

The range includes:

• Pressure compensators
• Pressure compensators with priority and bypass outlets
• Differential pressure sensing elements

The correct selection of these products can enhance machine performance, shorten the design process and minimize manufacturing costs of manifold blocks.

Differential pressure sensing elements - DPS2

For controlling pressure, flow or direction (including 3- and 4-way bridge circuits) the DPS2 is used with the aid of external pilot operators. The DPS2 elements are function building blocks which respond to pressure differential signals, providing the capacity to switch or modulate flows up to 303 L/min (80 USgpm) and pressure to 350 bar (5000 psi).

The choice of pilot arrangements related to DPS2 variants can minimize the number of construction holes in a manifold, simplifying design and reducing costs.

All poppet type DPS2 elements have recently been upgraded to 350 bar (5000 psi).
