Solenoid Operated Unloading Relief Valve
Varenummer: AS04G2Z14V
Parker’s solenoid operated unloading relief valve provides cost and space savings by combining a solenoid operated unloader valve and a system relief into a single cartridge valve and cavity. By utilizing a pilot operated design, this valve is capable of handling flows up to 60 lpm (16 gpm) and pressures as high as 280 bar (4000 psi). This valve is ideal for unloading circuits and allows pumps to unload to the tank at low pressure when no current is applied to the coil, therefore reducing power consumption and heat generation. Once current is applied, the valve will act as standard relief and can be used in several applications within mobile or industrial hydraulic systems.
Markets:
• Agriculture
• Construction
• Material Handling
• Miscellaneous Industrial
• Miscellaneous Manufacturing
• Miscellaneous Mobile
Features/Benefits:
• Two functions in one valve
• Integral 250 micron pilot flow filter
• All external parts zinc plated
• Factory set relief pressure or adjustable option
• Hardened, precision ground parts for durability
Value Statement:
Parker AS04G2 high flow relief valves incorporate a solenoid operated unloading feature to seamlessly divert pump flow to tank at low pressure when not required by work functions, which results in reduced heat and improved machine efficiency.
Applications:
• Pump unloader
• System relief
Additional Technical Insight:
Parker’s AS04G2 provides cost and space savings by combining a solenoid operated unloader valve and a system relief into a single 10-2 cavity. By utilizing a pilot operated design, the AS04G2 is capable of handling flows up to 16 GPM and pressures as high as 4000 psi. When no current is applied to the coil, pump flow is allowed to unload to the tank at low pressure therefore reducing power consumption and heat generation. Once current is applied, the valve will prevent the pump from unloading to tank as long as the pressure remains below the mechanically set maximum pressure.
Parker HCS offers four standard pressure settings, and can provide customer specific tamper-proof fixed settings upon request. The full 100-4000 psi max pressure range can be achieved by ordering any of the pre-set adjustable versions and adjusting the setting in the application.
The common cavity design enables this valve to offer design flexibility in many applications. It can be integrated into manifolds, mounted in-line with standard line-bodies, or sandwich mount into a D03 stack using our Cartpak BD03-PT stackable body. By utilizing Parker’s IP69K Super Coil technology, the AS04G2 can be used in a wide range of environmental conditions.
