Management System Certification & Export Compliance

When European and South American buyers audit a hydraulic component supplier, their first questions are: is the system certificate valid for our scope, which standard governs cylinder mounting dimensions, and what documents are needed to export into the EU. Below are the standards and document set we actually work to.

ISO 9001 Quality Management System
Incoming inspection, assembly, hydrostatic testing and shipment release for hydraulic valves, pumps and cylinders are all controlled under the system. Scope coverage is checked against the client certificate original; anything outside scope is reviewed separately as a non-standard item.
ISO 6020 / 6022 / 6023 Cylinder Mounting Dimensions
Bore, stroke, piston rod diameter and mounting flange hole spacing are drawn to the standard series, with actual dimensions on the nameplate so customers can match machine interfaces directly.
ISO 4413 Hydraulic Fluid Power Safety
Valve blocks, accumulators and piping accessories are checked against this standard for rated pressure, burst and leakage risk items. Manifold blocks come marked with port flow bore sizes and working pressure.
ISO 4406 Fluid Cleanliness
Assembly and testing run under graded cleaning throughout, with valve port sampling cleanliness held to 18/16/13 targets. Cleanliness and leakage test records ship with the goods.
CE and PED 2014/68/EU Applicability
Our products are supplied as components, so whether CE marking and the Pressure Equipment Directive apply is confirmed order by order against the specific contract product. Once confirmed, we issue a declaration of incorporation only; the declaration text is not written on this page.
Shipping Documents for Europe and South America
Packing list, invoice, certificate of origin, pressure test report and material certification are issued to EN 10204 3.1. Documents required for import clearance in the destination country follow confirmation by the client and their local customs broker.

Common market-entry requirements; applicability and documentation are subject to the destination country's current regulations and mutual confirmation.

How We Work: From RFQ to Shipment, With Documents You Can Check at Every Step

  1. STEP 01

    Inquiry and REXROTH-compatible selection check

    You receive a selection table matching valve type, bore, pressure rating and flow

  2. STEP 02

    Drawing and inspection plan confirmation

    We confirm the manifold machining drawing, ISO 6020 mounting dimensions and the inspection item list

  3. STEP 03

    7-day sample build with measured records

    Samples shipped within 7 days, with a key-dimension measurement sheet and hydraulic pressure test data

  4. STEP 04

    Batch production and lot traceability

    Continuous production to the same drawing, each unit carrying a serial number and material heat lot record

  5. STEP 05

    Third-party inspection and shipment release

    We accept SGS factory inspection and issue a pre-shipment inspection report once passed

  6. STEP 06

    Shipment and shipping documents

    Packing list, invoice, certificate of origin and CE declaration delivered with the cargo

Common Questions Before Ordering Hydraulic Valves and Pumps for Construction Machinery

What is the minimum order quantity? Can mixed specifications be combined?

MOQ is 2 pieces per model. Multi-spool valves and hydraulic pumps with the same port size and pressure rating can be combined; prototype samples are not subject to the MOQ.

What does the 7-day prototype process include?

Once you provide the drawings, port dimensions and pressure rating, we confirm the drawings and produce samples within 7 days, with dimensional inspection records available for the same batch.

How REXROTH-compatible are these products?

Port dimensions, mounting flanges and pressure ratings follow the same REXROTH models. Functional components and flow paths must be checked item by item before final confirmation.

What is the standard lead time? Are hydraulic cylinders slower?

Valves and pumps normally take 25–35 days; hydraulic cylinders to ISO 6020 mounting dimensions take about 30–45 days. Batch orders are confirmed against the production schedule.

Which inspection documents are supplied with the goods?

Each shipment includes the packing list, invoice, certificate of origin and pressure test report. Documents required for EU projects are confirmed order by order against PED 2014/68/EU and CE applicability.

What are the payment terms and warranty period?

Standard terms are 30% advance payment and 70% against a copy of the bill of lading. The warranty is 12 months from delivery, covering replacement of seals and shaft seals.

Send the model number or old-part drawing, and we will verify the interface and reply with a sample plan

Provide the matching REXROTH model, pressure rating and flow requirement, and we will return a manufacturable sample plan and quotation within 7 days.
