PARKER GRESEN

Parker Gresen is a brand within the Parker Hannifin Corporation, a global leader in motion and control technologies. The Gresen product line specializes in hydraulic valves and flow-control components designed for mobile and industrial equipment applications. Originating from the Gresen Manufacturing Company, which was acquired by Parker Hannifin, the brand has a long history of producing robust hydraulic components for off-highway vehicles, agricultural machinery, construction equipment, and material handling systems. 3G Electric supplies a range of Parker Gresen hydraulic valves, including manual selector valves, inline pressure relief valves, adjustable flow dividers, spool-type flow dividers, and stack valve accessories. These components are engineered to meet the demands of hydraulic systems operating under moderate to high pressures, with typical pressure ratings up to 5,000 psi and flow capacities ranging from 20 to 35 gpm. The product line includes four-way/two-position selector valves (models S-50 and S-75) for directional control, cast-iron pressure relief valves (RPL-12-A and RP51A-3000) for system protection, and flow control valves (CFQ-A-75 and CFQ-A-12) for precise flow regulation. Spool-type flow dividers (PDC-12-50) enable equal or proportional flow splitting in hydraulic circuits. Parker Gresen components are built with materials such as cast iron and feature port configurations including NPT and SAE O-ring boss, making them suitable for integration into existing hydraulic systems. 3G Electric supports the Parker Gresen line by offering these products for global procurement, with specifications clearly listed to assist engineers and maintenance managers in selecting the correct valve for their application. The brand's focus on reliability and standardization aligns with the needs of plant engineers and procurement specialists who require consistent performance in demanding environments.

Frequently asked questions

Common questions about PARKER GRESEN from 3G Electric.

What types of hydraulic valves does Parker Gresen offer through 3G Electric?

Parker Gresen offers a range of hydraulic valves including manual selector valves (four-way/two-position models like S-50 and S-75), inline pressure relief valves (RPL-12-A and RP51A-3000), adjustable flow dividers (CFQ-A-75 and CFQ-A-12), spool-type flow dividers (PDC-12-50), and stack valve accessories such as relief plug kits (K-20-NR). These components are designed for mobile and industrial hydraulic systems.

What are the pressure and flow ratings for Parker Gresen selector valves?

Parker Gresen manual hydraulic selector valves, such as the S-50 and S-75, are rated for a maximum operating pressure of 2,000 psi. The S-50 has a flow capacity of 20 gpm, while the S-75 handles 30 gpm. Both are four-way/two-position valves suitable for directional control in hydraulic circuits.

What materials are used in Parker Gresen pressure relief valves?

Parker Gresen pressure relief valves, such as the RPL-12-A, feature a cast iron body. This material provides durability and resistance to high-pressure hydraulic systems. The RPL-12-A is rated for a maximum pressure of 5,000 psi, while the RP51A-3000 has a range of 500 to 3,500 psi.

How do Parker Gresen flow dividers work in hydraulic systems?

Parker Gresen flow dividers, like the PDC-12-50 spool-type model, split incoming flow into two equal or proportional outputs. The PDC-12-50 has a 1:1 ratio and handles flow rates from 20 to 35 gpm with #12 SAE O-ring boss ports. Adjustable flow dividers (CFQ-A-75 and CFQ-A-12) allow manual adjustment of flow division via a lever.

What port configurations are available for Parker Gresen valves?

Parker Gresen valves are available with various port configurations. For example, the CFQ-A-75 flow control valve uses 3/4-inch NPT ports, while the CFQ-A-12 and PDC-12-50 use #12 SAE O-ring boss connections. Selector valves like the S-50 and S-75 typically have threaded ports compatible with standard hydraulic fittings.

Can Parker Gresen valves be used in high-pressure mobile equipment?

Yes, Parker Gresen valves are designed for mobile equipment applications. The pressure relief valves handle up to 5,000 psi, and selector valves are rated to 2,000 psi. Flow dividers and control valves are built with cast iron bodies to withstand the demands of off-highway vehicles, agricultural machinery, and construction equipment.
