Project Overview
This project involves the production of NG16 hydraulic valve body components for an industrial hydraulic system customer in India.
These hydraulic valve body components are widely used in industrial hydraulic systems and manifold blocks.
The order was completed before the Chinese New Year holiday and shipped on schedule after final inspection.
The product set includes:
- NG16 hydraulic valve body
- valve cover
- fastening bolts
- locating dowels
These parts are used in hydraulic control systems where precise internal bore machining and reliable sealing performance are required.
According to the project order documentation, the total order quantity for this shipment was 1,092 sets of NG16 valve components.
Standard Model – NG16 Hydraulic Valve
The NG16 hydraulic valve body is a commonly used standard size in hydraulic manifold systems. Because this model is widely used in industrial hydraulic equipment, customers and engineers often search for this model directly when sourcing replacement or custom components.
For this project, the valve body and cover were manufactured according to the customer’s specifications and assembled as complete sets before shipment.
Precision Bore Machining Requirement
One of the key technical requirements of this project was the precision machining of the valve bore.
The internal bore diameter is specified as:
Ø27 mm with tolerance -0.000 / +0.003 mm (maximum). proforma invoice YT25100
This tight tolerance ensures proper hydraulic sealing and smooth valve spool movement.
To verify the dimensional accuracy, we conducted internal inspection and recorded measurement videos. The inspection video was shared with the customer for confirmation before shipment.

Material, Surface Treatment and Assembly
The valve body components were manufactured and finished according to the project requirements, including:
- precision machining of valve bore
- drilling of hydraulic oil channels
- surface treatment and coating
- final assembly with cover, bolts and dowel pins
The external surface was coated in green RAL5021, a common color used in hydraulic system components.
Packaging and Shipment
All finished valve components were carefully inspected and packed before shipment.
The packaging process included:
- individual protection of machined surfaces
- carton packing
- wooden crate protection for international transportation
The shipment was prepared for export after final inspection and customer confirmation.
This project demonstrates our ability to supply precision hydraulic valve components with strict dimensional requirements and reliable quality control.
