Choose what arrives at your assembly line
The company identifies 宁波奥尔液压科技有限公司, using “Ningbo AORE Hydraulics” in its introduction. It describes threaded-cartridge and custom-manifold design/manufacture for mobile and industrial equipment. [1] Its catalogue separately lists functional assemblies, standard blocks, custom machining and accessories. [2]
Individual cartridge
Obtain the full order code, function diagram, cavity, seals, adjustment and model-specific installation requirements. Identify the receiving block and responsible circuit designer.
Machined manifold
Release a controlled block drawing with cavity/port identities, material, passages and inspection/cleanliness requirements. State whether cartridges and other fittings are excluded.
Assembled functional manifold
Align circuit and block revisions with valve codes, settings and accessory scope. Identify setting/test responsibility and the record that accompanies the delivered assembly.
Form tools, damping elements, seal kits and control pistons are listed separately. Their appearance in navigation does not prove inclusion with a valve or block.
Keep operating principle and port direction explicit
The relief range separates direct-acting, pilot-operated and other branches. The homepage names RP-14W-20A as a pilot-operated balanced-poppet relief reference; nearby RP and RD items retain different designations. [2] A family name cannot authorize substitution.
- CX-5A-2ED
- Catalogue label: free flow port 2 → port 1.
- CX-162A-2BA
- Catalogue label: free flow port 1 → port 2.
- CKIB-XCN and other three-port checks
- Separate pilot-operated check references; require their actual diagram and pilot arrangement.
These check-valve examples illustrate why direction matters; they are not RP-14W-20A’s diagram. “Industry-common cavities” in the company text is not a guarantee that two visually similar cartridges fit or behave identically. Compare exact cavity and circuit documents.
Turn the testing statements into deliverable records
The introduction claims 100% finished-product performance testing and million-cycle capability testing for standard products. [1] It does not supply an identified RP-14W-20A or order-lot report. A zero-leakage marketing phrase similarly needs pressure, flow, fluid, temperature and an agreed measurement criterion.
- 1
Freeze duty and documents
Identify circuit duty, fluid, thermal conditions, full code, cavity and block revision. Obtain the exact pressure/flow curves and permitted operating modes.
- 2
Agree factory records
Define valve-setting, leakage and functional checks where applicable, sampling and acceptance. Request results tied to the delivered codes/lot or assembled block.
- 3
Assign system validation
Keep component tests separate from the installed circuit’s function and safety checks. Name the integrator, commissioning conditions and change-control responsibilities.
The supplier’s dated fluid guidance discusses mineral oil, NBR seals and cleanliness. [4] [5] Obtain the exact seal/fluid variant and model-specific cleanliness/installation requirements. ISO 4413’s publisher scope includes hydraulic-system construction, modification and installation; it is not a certificate for this offer. [6]
Stock age matters to the published warranty
The reviewed statement is dated 18 March 2020.
| Published condition | Purchase question |
|---|---|
| Original purchaser; 12 months after first installation, capped at 20 months from production date. | What manufacture date and current agreed coverage apply to this order and spare stock? |
| Seals/O-rings and non-AOER accessories excluded from that statement. | Which separate terms cover seals, sensors, fittings and other supplied components? |
| Contamination and unauthorized handling/changes excluded. | What cleanliness, handling, installation and authorization records must be retained? |
These are dated website terms, not a newly negotiated warranty. [3] Confirm them in the current offer. The same statement puts final selection and system validation on the user and requires written permission for listed restricted applications; review the actual use with the supplier rather than treating a valve catalogue as application approval.
Two history dates remain unreconciled
The homepage says March 2003; the company introduction says January 2009. [1] [2] We do not assign a verified founding date. The introduction references ISO9001:2008 and TS16949 process control without an authenticated current certificate; those statements are not current certification badges.
Confirm the contracting holder/site and current qualification documents if required. The live website was readable on 11 October, replacing the earlier connection-failure note. The linked NewAOER.pdf could not be retrieved successfully in this review, so no unseen curve or cavity page is cited as checked.
