Reliable Excavator Parts Seals: Choose Tonkee
Tonkee Machinery Co., Ltd. - Your Trusted Partner in Hydraulic Excellence
In the world of heavy machinery and construction equipment, the performance and reliability of hydraulic components are paramount. These systems are the muscle and sinew of excavators, bulldozers, and cranes, enabling them to perform demanding tasks with precision and power. At Tonkee Machinery Co., Ltd., we are dedicated to providing genuine and high-quality hydraulic parts that ensure your equipment operates at its peak performance. This article explores a range of critical components, including piston pumps and control valves, highlighting their specifications and applications.

Piston pumps are the beating heart of any hydraulic system. They convert mechanical energy into hydraulic energy, generating the high-pressure fluid flow needed to power cylinders and motors. The efficiency and durability of a piston pump directly impact the overall performance and lifespan of the machine. Our selection includes main pumps from industry leaders like **NACHI, KYB, and KAWASAKI**, each known for their robust design and superior performance.
While the pump provides the power, the **main control valve (MCV)** directs it. This intricate component precisely controls the flow and pressure of the hydraulic fluid to different parts of the machine, allowing the operator to maneuver booms, arms, and buckets with fine control. A high-quality control valve is essential for smooth and efficient operation, preventing system shocks and ensuring safety. We offer a variety of genuine MCVs for brands like **HITACHI and VOLVO**, guaranteeing seamless integration and reliable performance.
To help you find the right part for your needs, we have compiled a list of some of our key products. Each item is genuine, ensuring it meets the stringent quality standards required for heavy-duty applications. Our catalog is a testament to our commitment to providing genuine, reliable parts for a wide range of machinery.
