Strainers
High-Quality Hydraulic Strainers
The hydraulic strainer removes large debris and coarse particles from hydraulic fluid, preventing contaminants from entering critical system components. By capturing solid impurities at an early stage, the hydraulic strainer helps protect pumps, valves, and other sensitive equipment from damage, ensuring stable and efficient system operation.
Installed as a first-line filtration device in hydraulic systems, JUNWELL’s hydraulic strainers play an essential role in maintaining fluid cleanliness and reducing wear caused by foreign particles.
Our strainers are widely used across engineering vehicles, agricultural machinery, marine equipment, automotive systems, and various types of industrial and special-purpose machinery. They are suitable for system repair and replacement applications.
Fluid Level Gauges
Fluid Level Gauges with Superior Clarity and Leak-Proof Design
A fluid level gauge, also known as a fluid level indicator, is a device used to measure and display the level of liquid (such as oil, coolant, fuel, or hydraulic fluid) inside a tank, reservoir, or gearbox. It allows operators to monitor fluid levels quickly and accurately, helping prevent damage from low fluid conditions.
JUNWELL’s fluid level gauge features crystal-clear visibility and a robust, leak-proof design, allowing operators to easily check oil levels, ensuring safe and efficient system operation.
Our fluid level gauges are widely used in hydraulic systems in construction equipment, agricultural machinery, marine vessels, commercial vehicles, and special machinery. JUNWELL’s fluid level gauges deliver reliable performance and long-lasting durability.
Hydraulic Check Valves, Needle Valves & Flow Control Valves
Precision Valves for Reliable Hydraulic Flow Control
JUNWELL offers various valves, including hydraulic check valves, needle valves, and more. Our valves are designed for precise hydraulic flow control in industrial systems. They allow unidirectional flow, fine adjustment, or complete shut-off of fluid lines, ensuring safe and efficient operation in demanding applications. Engineered for durability and high-pressure resistance, they offer stable performance under continuous industrial use.
These valves are widely applied in hydraulic systems used in engineering vehicles, agricultural machinery, marine equipment, automotive systems, and various heavy-duty industrial machines. Whether for repair or replacement, our valves deliver consistent flow regulation and system protection.
Made with precision manufacturing standards, our hydraulic valve solutions improve system efficiency, reduce leakage risk, and extend equipment lifespan.
Filler Breather Filters
High-Quality Filler Breather Filters
JUNWELL’s filler breather filters combine oil filling and air filtration functions in one compact design, helping maintain oil cleanliness in hydraulic and lubrication systems. Equipped with a built-in air filter element, it effectively prevents dust and contaminants from entering the tank during air exchange, reducing the risk of oil contamination and extending equipment service life.
The FB Series and PFB Series are designed to protect hydraulic components from wear, damage, and system problems. This helps make the system more dependable and saves space when installing. These filler breather filters come in different sizes and can handle various flow amounts. They are suitable for hydraulic reservoirs, lubrication systems, power units, industrial machinery, automation equipment, and heavy-duty applications.

Oil Coolers
Caution:
The ports on both sides of the cooler can be oil inlet or oil outlet according to your needs. However, water must enter into the system from the underneath water inlet and come out from the upper water outlet. Only fresh water can be the cooling medium. It is imperative to maintain the oil and water in equal volume when the cooler is used in the application of viscous oil.
Max. pressure: oil side 10 kg/cm², water side 7 kg/cm²
