6061 Aluminum Pressure Reducing Valve Piston
The pressure reducing valve piston is made from 6061 aluminum alloy turning using precision CNC turning. This aluminum CNC turning part is used in valve assemblies, where it reciprocates within the valve cavity to regulate oil pressure.
The internal groove requires a surface roughness of Ra ≤ 0.8. No steps, sharp edges, or burrs are allowed, as they may damage the sealing ring during assembly and lead to product failure.
The part contains multiple radii and fillets. To control production costs, customers often require manufacturing using automatic lathes. With extensive experience in custom non-standard parts, we are able to provide practical solutions to achieve cost reduction and efficiency improvement. Our expertise enables us to optimize both cost and performance for precision components.
Stable Production Experience
As a key component, this CNC turned aluminum part requires 100% consistency in quality. To ensure product stability, our factory has established standardized operating procedures covering:
• Raw material inspection
• CNC turning process control
• Cleaning procedures
• 100% final inspection
All processes are documented and strictly followed.
This product has been in continuous production for nearly 8 years, with zero quality complaints. We have been recognized as an "Excellent Machining Partner" by our customers for three consecutive years.
Main Applications
Hydraulic Systems in Construction Machinery
The pressure reducing valve piston is a precision 6061 aluminum turning part widely used in hydraulic systems of construction equipment such as excavators and cranes. The piston movement regulates oil pressure within the system. The lightweight nature of aluminum makes it ideal for high-frequency moving components.
Pneumatic Tools and Compressors
In air compressors and pressure regulating valves, aluminum pistons offer good corrosion resistance and wear resistance, ensuring reliable long-term operation under high-pressure air conditions.
Medical Gas Equipment
This component is also used in oxygen cylinders and ventilator pressure regulators. Aluminum is easy to sterilize and non-toxic, meeting medical hygiene standards.
Material Information – 6061 Aluminum Alloy
6061 aluminum alloy is one of the most widely used heat-treatable aluminum alloys and is often referred to as a "general-purpose alloy" due to its balanced mechanical properties.

Strengthening Mechanism
The strength of 6061 aluminum is primarily achieved through heat treatment (T6 condition). During this process, magnesium and silicon form fine Mg₂Si strengthening particles, which are uniformly distributed in the aluminum matrix and effectively hinder dislocation movement, thereby significantly improving strength and hardness.
