This pressure must be equal to the pressure setting of the unloader pilot stage to initiate unloading; the system pressurizes again when this pressure drops by approx. This cartridge arrangement has a 1: Installation dimensions unchanged for design numbers 10 to 19 and 40 to 49 inclusive. Reducing valve arrangements described in this catalog can be built djn system manifold assemblies with directional, manually adjustable flow restrictor and pressure relief functions in cartridge form.
Torque to Nm lbf ft Port B Size 03 pilot control valve to be ordered separately. Port Z1 should be blocked when not required. All features must be specified when ordering; those in brackets are optional or apply only to specific models.
Positive closing using pilot pressure. In this form, they serve as a one-way valve, allowing free flow in one direction while blocking flow in the reverse direction.
Note that the circuitry i. Good practice suggests that detented pilot valves, e. Sizes 16 to 63 Sizes 16 to A right hand model would allow venting when the solenoid is energized. Cartridge valve systems will become more cost effective if some of the following design parameters are significant. Presses Plastics molding machines Die casting machines Shears and balers Machine tools and metal forming machinery Steel mill machinery and other primary metal processing equipment Mobile vehicles Marine Response Time Response time is generally faster than that of large spool type valves which have to clear their overlap before flow starts.
Initially the flow through the pilot valve equals the flow through the slot dij the volume displaced by the opening movement of the main dun. Difficult environments could mean that extra screening may be necessary to avoid the interference. All functions are available in sizes 16, 25, 32 and Electronic controllers for 42342 pilots are also shown.

dij For stable valve operation follow Vickers recommendations for selection of spring for each size of insert. B T Profile for size 16 only Z2 85,2 3.
Single or dual solenoid pilots are applicable Figure 15depending on circuit requirements. Unlike most reducing valves, pilot pressure is obtained from high-pressure port B rather than from reducedpressure port A, thus providing significantly more flow capacity.
Therefore the position of the main poppet is controlled by a closed-loop system with a variable orifice in the poppet acting as the internal position feedback element. The Z2 port is used for remote control djn the dynamic insert. Speed control in accordance with machine operating cycles or programs. Metric bolts supplied with cover sizes 16 to 40 inclusive, type -B When the solenoid is energized, pressure at port A P is limited by the setting of the 2432 in the cover.
Simple on-off solenoid pilot controls, as well as air operated types, are also available.
Location for optional orifice Z2. Conforms to ISO For customers wishing to use UNC mounting bolts as offered in this catalogVickers recommendations for thread size dij tapping depths are given in the table at the bottom of this page.

For dimensions of CVGC-3 module see pageand for adjustment types see page With cartridge valves, flow starts as soon as the poppet starts to lift off the seat in the cartridge sleeve. The higher of these two pressures is then available at pilot port P to close the insert via the size 03 solenoid operated valve.
In Figure 53 the cartridge valve insert functions as a pilot-operated check valve. The maximum pressure limit at pilot ports X, Z1, Z2 and AP and pilot valve interface ports P, T, A and B is generally bar psidependent on the limit of any associated pilot valve or module.
Control ports alignment ensured by cover pilot diameter. Also minimum centerline to centerline distance for two identical cavities in a manifold block. The D16 insert is not to be used as a pressure control such as relief or counterbalancing. Springs, seals, spools and poppets ar available, as defined in Vickers Service and Spares literature.
Electrically proportional control is also available. Sizes 16 to 40 When used with an electrohydraulic proportional pressure control connected to Z1 portpressures as low as 1,5 bar 22 psi are controllable at port A, making it ideal for plastics injection molding machine applications. Options include electrical selection of high and low pressures, and electrohydraulic proportional control of reduced pressure.
When the solenoid is energized the unloader function operates via pilot port X as described above. Contact your fluid supplier for seal recommendations. For selection of pilot control module CVGC-3, see pages At both of these positions the main flow path A—B is closed. Others provide flow restrictions between ports A and B and internal pilot orificing between port A and spring chamber AP.
