Flow from port A to port B is always blocked.
Slip-In Cartridge valve, ISO (DIN )
B T Profile for size 16 only Z2 85,2 3. Provides greater sealing reliability, particularly at high pressures.
Pilot pressure from either a remote source SWD modelsor from a valve mounted directly onto the cover SWD3 models can be used to hold the spool fully closed.
When the solenoid is energized, pressure at port A P is limited by the setting of the adjuster in the cover. Complete Standard cover dih incl. Such applications include die casting, deep drawn presses, injection molding, container handling, shovel loaders, forestry and dump trucks.
The command signal in this feedback system is pilot flow, as set at the proportional pilot throttle valve 4. Accurate and repeatable switching points. Remote Pilot Operated Functions Remote 2442 arrangements pilot not integrally mounted on cartridge cover require the dib of pilot flows and pressures appropriate to the application and within the limits of any associated pilot valves and modules, whichever have the lower limits.

The pilot pressure is applied via the Z2 port on the manifold if there is no pilot valve or via the B port on the size 03 interface. Slip-in cartridge, direct operated relief for mineral oil. Maximum pressure bar psi Flow ratings See model code CVI page 86 Controlled flow characteristics See graphs on page 88 Pressure drop, free return flow See graphs on page 90 Dynamic performance: For available orifice kits, which should be ordered separately, see next page. Orientation pin As can be modified for Normally Open function: Basic poppets are illustrated.
In Figure 55 the solenoid-operated pilot 24324 valve is mounted directly on to the control module. When both solenoids are de-energized, system pressure is vented to the reservoir. The dynamic insert can only be used with the special dynamic cover. Sizes 16 to 40 When the solenoid is de-energized, Figure di, the cartridge is vented. The F insert area ratio 1: The use of synthetic fire-resistant fluids requires a valve with special seals. Cartridge Covers are used in conjunction with cartridge valves to create a complete assembly.
Electronic controllers to be used with the pilots are also shown. Cartridge valve systems will become more cost effective if some of the following design parameters are significant. The calculation provides a starting point for determining the right orifice for the application.
The spool center condition of the solenoid pilots also depends on the circuit function desired. Sealing is both on the flat cover face and around the ring on the insert sleeve, see Figure Installation dimensions unaltered for design numbers 10 to 19 inclusive.
Cracking pressure, bar psi L – 0,3 4. With cartridge valves, flow starts as soon as the poppet starts to lift off the seat in the cartridge sleeve. The sizing and combination of orifices fitted into these pilot valves have been determined by testing to give good response and stable operation across a wide range of average system parameters using standard covers i.
For industrial and mobile applications. Turn cw to increase pressure setting; ccw to reduce setting 2 holes for attachment of CVI insert dinn Y See page for information on bolt sizes, bolt kits and assembly torques X Location for fixed orifice X Type K only: The cartridge insert consists of a sleeve, a seating poppet area ratio 1: Simple on-off solenoid pilot controls, as well as air operated types, are also available.
Z1 Orientation pin Location for optional orifice Z1 Minimum clearance for removal of cover from manifold For thread sizes and idn kits see page For selection of pilot control module CVGC-3, see pages Thus by controlling flow through the pilot valve, the main poppet can be controlled in any position from fully closed to fully open.
Therefore, there is virtually no leakage between ports A and B when the poppet is held in the closed position Figure 2, page The A-port area is the circular area defined by the seat diameter.

Single or dual solenoid pilots are applicable Figure 15depending on circuit requirements. Size 03 pilot control valve to be ordered separately. USgpm 16 2,0 0. For additional information, request catalog Others provide flow restrictions between ports A and B and internal pilot orificing between port A 244342 spring chamber AP.
Adjustable Stroke Limiter and Directional Functions: The Vin insert 1: Damping can be achieved with a model R16 insert area ratio 1: Contact Vickers for application assistance. For bidirectional control of flow ie flow A to B and B to A at different times during an operating cycle port X must be connected to both A and B via a shuttle valve see diagram. The pressure differential between inlet and outlet must be at least 5 bar 72 psi for optimum reduced pressure control for low flows.
This feature is of benefit in any application where there must be absolutely no risk of the cartridge even momentarily opening during pilot pressure changeover.
