SOLENOID VALVE

Parker’s D1VW directional control valves are high performance on/off direct operated hydraulic valves. There are 15 solenoid voltage options including DC, DC rectified and true AC voltages. There are 9 basic termination options including DIN, Deutsch, conduit box with wires and conduit box with plug-in coils. The conduit box with plug-in coils also allows for connections including terminal strip, Manaplug (Brad Harrison) and micro connection (M12 connector). D1VW valves are available with other options such as soft shift tubes (4 orifice size options), monitor switches, extended manual over rides and surge suppression diodes. DIN connector and Conduit box connections provide an IP65 (NEMA 4) ingress rating

The D1VW valve is well suited for both the industrial and mobile applications. Painted bodies and Deutsch connectors are offered for tough environment applications.

RELIEF VALVE

Well known as excellent pressure relief valves, Parker's series R4V/R6V and R4V/R6V Proportional for subplate mounting work stable across the whole pressure range and thus contribute to a smooth-running operation. Additionally they provide a wide range of options and connections for a versatile use in various applications.

Pilot operated pressure relief valves series R4V (DIN 24340 Form D) and R6V (DIN 24340 Form E) consist of a manually or a proportionally adjusted pilot stage and a seated type main stage. A vent function with a solenoid operated directional valve is available for circulation at minimum pressure. The optimum performance of the proportional version can be achieved in combination with the digital amplifier module PCD00A-400.

Function: Series R4V/R6V System pressure in port P is applied via the X gallery to the spring loaded cone in the pilot head. The pilot head controls the pressure in the Z area on top of the main cartridge which is additionally kept close by the main spring. If the pilot pressure exceeds the setting pressure the pilot cone opens and thus limits the pilot pressure. When the system pressure exceeds the pilot pressure plus the spring force, the main cartridge opens to port T and limits the pressure in port P to the adjusted level.

Series R4V/R6V with vent function Additionally to the relief function, a solenoid operated vent valve connects the Z area to tank. This allows oil circulation from P to T at minimum pressure drop. The vent valve can either be a standard CETOP 03 valve (R6V) or a sandwich unit (R4V). For both types the vent position can be either at the energized or de-energized solenoid.

PROPORTIONAL VALVE L90

L90LS has a wide range of selectable functions, offering great flexibility in terms of system structure in simple as well as advanced hydraulic system solutions. L90LS is a result of Parker’s wide experience in mobile hydraulics, offering excellent performance, made with high grade materials and precision manufacturing. L90LS can be equipped with manual, hydraulic or electrohydraulic spool actuators in any combination. Each valve section can be optimized for its particular function in the machinery, with a large range of main spools, pressure relief valves, pressure compensators, signal pressure limiters and other performance enhancing functions.

The L90LS hydraulic valve can be constructed in many different designs, with different inlet sections, work sections, end sections and also generic function manifolds for example to obtain proportional pressure control. The L90LS can also be combined with the bigger K220LS directional control valve in order to further optimize functional performance in machinery with large variations in flow requirement.

For complete customer-specific functional adaptation and to accommodate every conceivable need in terms of auxiliary function control, the L90LS can be combined with tailor-made function manifolds, consisting of components from Parker's many product divisions.

The L90LS is designed to operate in perfect harmony together with Parker pumps, motors, electronic systems and joysticks as well as with equipment from other manufacturers.

COMMERCIAL VALVE DVA/DVG

The VA and VG model valves are updated versions of our proven A20™ and A35™ units. The VG models are cast from compacted graphite, a high strength iron alloy, which allows the valve to be rated to 3500 psi. VA models are cast from gray iron and are rated at 2500 psi. These open-center, directional-control valves are available in parallel, tandem, and series circuitry. As needed, the sectional, stack-type construction provides flexibility for the addition of subtraction of work sections to an existing valve bank. This design also permits the combination of parallel, tandem, and series circuitry in a single bank. The internal coring of each valve section determines its circuitry and the number of gasket seals required. All sections with optional features, such as port relief valves, crossover relief valves, and anticavitation checks, are dimensionally larger when measured from the top of the port to the bottom of the housing. These are referred to as “hi-boy” sections. Those without work-port options can use the low-profile castings, which are called “loboy” sections.

CATDRIGE VALVE

Parker’s 2-way poppet style solenoid valves feature a proven design that ensures very low leakage when flow is blocked in one direction and minimized pressure drop in the free flow position. These valves can operate with hydraulic system flows as high as 260 lpm and pressures up to 350 bar with normally-open or normally closed configurations available. Parker’s 2-way poppet solenoid valves are ideal for unloading and load holding applications that require low poppet style leakage within mobile, industrial, or manufacturing markets.

Applications: • Unloading circuits • Load holding applications • Lift circuits

AUTOCLAVE VALVE

Parker Autoclave’s VRMM Series micro-metering valves are designed for applications where more precise control of small flows is required than is possible with a standard regulating stem. Barrel and Thimble micrometer design permits settings to be repeated. Metering is effected by a finely tapered stem acting in a precisely mated replaceable seat. Very fine stem position is achieved utilizing a 40 TPI thread. The Barrel and Thimble are set for proper metering at the factory.

These valves are designed for metering only and cannot be used as a shutoff valve. Minimum flow is factory set and occurs at “0” position. DO NOT OPERATE THE VALVE BELOW THE ZERO POSITION OR DAMAGE WILL RESULT. When shutoff action is required, a correlated shutoff valve from Parker AE series 10V, 30VM or 60VM should be installed in series with the micro-metering valve.
