2. component design, system integration help, and after-sale services; thus, customers do not simply receive products, but power transmission solutions. Applications Across Industries Fluid power systems are vital in: •Manufacturing: operating presses, robotic arms, and assembly lines. •Construction: operating excavators, loaders, and cranes. •Agriculture: operating tractors, harvesting machines, and sprayers. •Aerospace and defense: operating and controlling flight control systems, landing gear, and weapons. •Transportation: operating assembly lines and hydraulic. 4L, LLC’s components are engineered to perform in all these demanding environments, offering consistent power, precision, and reliability. Core Components of a Fluid Power System A well-designed fluid power system consists of several essential components. Each component serves a critical role in maintaining performance, reliability, and control. 1. Pumps and Compressors Pumps (for hydraulics) and compressors (for pneumatics) provide the power in fluid power systems. They take mechanical energy from motors or engines and convert it to fluid energy producing flow and pressure. •Hydraulic Pumps: Hydraulic pumps come in several design types including gear pumps, vane pumps or piston pumps. Each design will have a specific application with trade-offs based on pressure, efficiency and flow rate. •Pneumatic Compressors: Pneumatic compressors generate and maintain the air pressure the pneumatic system requires. The main

3. types of pneumatic compressors are rotary screw, reciprocating, and centrifugal. 4L, LLC sells high-performance pumps and compressors focused on energy efficiency, low vibration and long life. All components are drilled down for rigidity, reliability and durability even in demanding operating situations. 2. Actuators Actuators are the work-performing components that convert the fluid’s pressure and flow into mechanical motion. They can generate linear, rotary, or oscillatory movement depending on the design. •Hydraulic Actuators: Also known as hydraulic cylinders, these deliver significant force with high precision, making them essential in heavy-duty applications like presses, loaders, and cranes. •Pneumatic Actuators: These provide fast and smooth motion and are commonly used in automation lines and robotic systems. 4L, LLC’s actuators are engineered with precision materials to reduce friction, enhance response time, and maintain high operational accuracy. Their commitment to quality ensures longer lifespan and reduced maintenance costs. 3. Valves The heart of fluid power circuits are valves, which control the direction, pressure, and fluid flow regulator to ensure that the motion is as desired, with the intended force.The main types include: There are three primary classifications of valves: •Directional Control Valves: Control the direction of flow through the circuit. •Pressure Control Valves: Control the pressure within an operational and safe value.

4. •Flow Control Valves: Control the flow rate to regulate the speed of actuators. 4L, LLC offers a broad selection of manual and electronically controlled valves that incorporate smart technologies which allow for remote monitoring and automated adjustments for optimized system performance. 4. Reservoirs and Accumulators Reservoirs serve to store and condition hydraulic fluid in the hydraulic system. They are used to filter and settle contaminants from the hydraulic fluid, to dissipate heat, and to provide the required volume of fluid for the operation of the system. Whereas accumulators are used to store energy in hydraulic systems as pressurized fluid, and are primarily used to maintain consistent system pressure. 4L, LLC designs reservoirs and accumulators with advanced thermal management capabilities, and using corrosion-resistant materials, to provide longer fluid life and improved stability of the overall hydraulic system. The Importance of High-Quality Components A fluid power system is only as strong as its weakest link. Poor quality parts can cause leaks, pressure loss, expedited wear or failure of a system. Using superior quality, precisely manufactured parts, like 4L, LLC products, will hold your systems operating reliably for the long haul, with minimal maintenance for you to deal with, saving you time, money, and productivity. 4L, LLC focuses on: •Precision Engineering: All of our products are precision engineered to our specifications, taking advantage of advanced technology, controls, and validated performance.

5. •Material Excellence: We only choose durable metals, composites, and elastomers capable of wearing, corrosion, and temperature longevity. •Testing/Validation: Each performance component undergoes testing of performance and product validation under extreme conditions within industry. •Customization: 4L, LLC components are custom and engineered to your operations and specifications. The Future of Fluid Power Systems Combining digital technology with fluid power systems is the next evolution for the industry. Hybrid systems that include hydraulics, pneumatics, and electronics are now truly enabling intelligent flexible and energy-efficient systems. 4L, LLC is leading this initiative by developing intelligent control systems that will, in the future, bridge classical mechanical power with present digitization. As automation expands and industries demand more efficient machinery, the role of companies like 4L, LLC will become even more vital. Their ongoing investment in technology, quality, and customer satisfaction ensures they remain a trusted partner in advancing industrial power systems. Conclusion Fluid power systems are the lifeblood of modern industry — powering machines, enabling automation, and driving innovation. The effectiveness of these systems depends entirely on the quality and integration of their components. With its strong commitment to engineering excellence, product reliability, and sustainability, 4L, LLC continues to set the benchmark for performance in the field of fluid power.

6. In today’s competitive industrial marketplace, efficiency, reliability, and accuracy are critical to any business being successful. Many of the world’s industries rely on fluid power systems — which are complex, interconnected systems that transmit and control power to do work by means of pressurized fluids — to maintain operational excellence. These fluid power systems (hydraulics or pneumatics) are utilized in various markets, including manufacturing, construction, agriculture, aerospace, and automotive. The efficacy and viability of these systems are impacted by the quality and performance of the  fluid power system components. This is where we — 4L, LLC — serve as a leader in precision engineered components that increase productivity, reduce operating costs, and promote sustainability.
