Professional FAQ: Double Acting Power Unit

1. What primary materials are used in a high-end double acting power unit?

A: Top-grade units use A356-T6 aluminum (for housing and tank), 1045/4140 steel (shafts and gears), and specialized seals (e.g., Parker Nitrile) to secure both durability and a high strength-to-weight ratio.

2. What certifications or standards must a reliable unit meet?

A: ISO 9001:2015 quality management ensures process control, while ISO 4413 governs hydraulic safety and system integrity. CE and RoHS marks indicate global compliance and environmental responsibility.

3. How do flow rate and pressure influence actual application?

A: Flow rate (e.g. 8–15L/min) affects actuation speed, while rated pressure (up to 21 MPa) determines max load and force capability. Oversizing these lowers efficiency; precise engineering is key for optimized performance.

4. Are custom voltages, controls, or mounting available?

A: Yes, reputable manufacturers like Shenghan offer 12V/24V/48V DC, 220V/380V AC motors, multiple valve logics, and universal/flange mounts tailored to client specifications.

5. How is leakage prevented in premium units?
