Quality Control

Quality Follow-up for Brass Valve Supply

Consistent quality starts before production and continues through manufacturing, inspection and final shipment.

SUNRICH FLOW works with selected manufacturing partners to confirm product requirements, coordinate suitable production resources and follow key quality points throughout each order.

Before Production

Clear Requirements Come First

Many quality problems begin with unclear specifications. Before production, key product requirements should be confirmed as clearly as possible.

01

Product Specifications

Valve type, size, structure and other key product details are confirmed before production coordination.

02

Material & Thread

Material requirements, thread standards and connection details are confirmed according to the project.

03

Drawing or Sample

Drawings, reference samples or confirmed specifications can be used to clarify important product details.

04

Sample Approval

For suitable projects, sample confirmation can be discussed before bulk production.

From Material to Shipment

Key Quality Stages We Follow

Different stages address different quality risks. Inspection requirements depend on the confirmed product specification and customer requirements.

06 / SHIPMENT

Packing & Shipment

Packing, labels, quantities and shipment details are coordinated according to the confirmed order.

What We Check

Inspection Points Based on Product Requirements

Inspection items vary by valve type, application and customer specification. Typical quality points may include:

01

Material

Material requirements according to the confirmed product specification.

02

Dimensions

Key dimensions, overall size and relevant dimensional requirements.

03

Threads & Connections

Thread type and connection details according to the agreed specification.

04

Pressure & Sealing

Pressure and leakage requirements according to confirmed testing conditions.

05

Appearance & Assembly

Surface condition, assembly status and agreed functional details where applicable.

06

Marking & Packaging

Logo, product marking, labels, cartons and other agreed packaging details.

Project-specific Requirements

Quality Requirements Can Vary by Market and Project

Additional inspection, documentation or certification requirements should be confirmed before quotation and production.

Inspection

Third-party Inspection

Customer-appointed or third-party inspection arrangements can be discussed depending on the project requirements and order conditions.

Documentation

Certification & Special Requirements

If a project requires specific certification, material documentation, testing records or other compliance information, these requirements should be confirmed in advance.
