Quality Control
A Quality System You Can Audit — Not Just a Promise
Hydraulic valves fail silently and fail expensively. That is why we test every unit, trace every batch and document every shipment.
Process
From Raw Material to Shipment
- STEP 01
Raw Material Inspection
Incoming steel and components are verified against material certificates before entering production.
- STEP 02
Precision Machining
CNC machining centers hold tolerances to microns; critical bores are honed for leak-free sealing.
- STEP 03
100% Function Testing
Every single valve is pressure- and function-tested on calibrated test benches — no batch sampling.
- STEP 04
Packing & Delivery
Anti-rust treatment, export-grade packing and full documentation accompany every shipment.
Testing Capabilities
What We Measure Before You Receive It
100% Pressure Testing
Every single valve is pressure-tested on calibrated benches — no batch sampling.
Dimensional Inspection
Critical bores and spools are checked against drawings with micron-level instruments.
Material Verification
Incoming steel is verified against mill certificates; material test reports available on request.
Function & Endurance Test
Solenoids are cycled and response-tested to confirm switching performance and leak-free sealing.
Pre-Shipment Inspection
A final AQL inspection covers marking, packing and documentation before release.
Batch Traceability
Every production batch is recorded — from raw material lot to final inspection report.
Certifications & Warranty
Documented, Not Just Claimed
Inspection reports, material certificates and test data are shipped with every order. On-site audits and third-party inspections (SGS, BV, TÜV) are welcome.
FAQ
Quality Questions, Answered
Do you really test every valve before shipping?+
Yes. Unlike batch sampling, every VEYDOR valve passes an individual pressure and function test on calibrated benches before it is packed. Inspection records are kept per batch and available on request.
What certifications do you hold?+
Our quality system follows ISO 9001:2015. Material test reports (MTR) are provided with shipments, and CE documentation is available for applicable models. We can support customer-specific audits and documentation packages.
What is the MOQ and typical lead time?+
MOQ is model-dependent (usually from 1–10 pieces for stock series, mixed models welcome). Typical lead time is 7–15 days after order confirmation, depending on the series and quantity.
Do you offer OEM / ODM service?+
Yes. We produce under your brand — private labeling, custom color/cartons and customer part numbers. Send us your drawings or specifications and we will quote tooling and unit cost.
What warranty do you provide?+
12 months from shipment against manufacturing defects. Warranty claims are handled with replacement parts or units after failure analysis.
How are valves packed for export?+
Anti-rust treatment, plastic sealing, then export cartons or wooden cases. Multi-model mixed containers are supported, with full packing lists and shipping marks.
