FAQ

How do you ensure product reliability without in-house production?

We hold ISO 9001/TS 16949 certifications and have over 15 years of hydraulic manufacturing experience. Each batch undergoes a 5-stage quality verification, including pressure cycle testing and material composition analysis.
How to handle component failures during the warranty period?

We offer a 12-month limited warranty (covering manufacturing defects). Simply send a diagnostic video via our platform, and our engineers will confirm repair/replacement solutions online.
Can technical drawings be provided for custom projects?

After confirming the deposit, engineering schematics can be shared under an NDA. Our advanced production system shortens lead times by 30% compared to traditional suppliers.
What is the minimum order quantity (MOQ) for hydraulic valves?

Standard models have a flexible MOQ of 50 pieces. Sample orders start from 20 pieces.
How to handle urgent breakdowns?

Our national partners stock critical spare parts in 6 regional centers, with priority delivery services available at major ports.
What are the payment terms for new customers?

A 50% T/T advance payment is required for the first transaction. Payment terms can be further discussed after three consecutive successful deliveries.
Are certification documents available?

Each shipment includes CE/ISO/REACH certificates. Special certifications (e.g., ATEX) require 45 days' prior notice.
Can you provide samples?

Yes. We can supply samples for your testing and verification needs. For sample requests, please inform us of the specific product model, quantity, and any special requirements. We’ll communicate details like sample preparation time, shipping arrangements, and relevant costs (e.g., sample production fees, logistics charges; partial costs may be negotiable under certain conditions).
