VIHUNG VALVE specialise in the supply and support of industrial valves and valve related products.

Industrial valves are crucial components in various industrial processes as they control the flow of liquids, gases, and other fluid substances These valves play a significant role in maintaining the safety, efficiency, and performance of various industrial systems, and therefore, it`s essential to have professionals who can install, repair, and maintain them. This is where industrial valve specialists come into the picture.We introduced advanced production and testing equipment at home and abroad, introduction of three-dimensional simulation manufacturing test design system, 3D printing technology, optimization and upgrading of products, reliable quality, stable performance, long service life, using precision machine tool equipment, vertical machining center, high-precision CNC machine tools to ensure high precision of product parts,are all guaranteeing that VHV Vihung`s products and services are the best you can find.

In order to the further development.the VHV established the CAD valve design center.the new production research center.3D analog design system and valve testing center.lt should be mentioned that the valve testing center is equipped with advanced processing machines.Direct reading spectrum analyzer.the valve curved bench.low temperature impact test machine.tensile testing machine.digital valve testing machine.torque and life test device.physical and chemical analysis laboratory.impact fatigue test device.With scientific and comprehensive test machines. VHV make the quality of product in international level and provide you products in good quality.VHV has become a fastest growing and leading enterprise in China.With careful operation and strict check, our products are in good quality.Strict attitude created excellent quality of VHV.
Quality control is a top priority at VHV. During the production process, we employ several stages of quality control:
Quality control of incoming materials and components

Incoming materials undergo several types of analysis - for example material analysis hardness analysis or porosity analysis Further analysis is carried out in cooperation with external laboratories and certification authorities.
In-production quality control

During the production stage, all machined components are being checked for accuracy. For this measurement.CNC controlled 3D machines are used (Contura G2 RDS 1000) with error of measurement at 1000 mm = 3,5 urn. Designated specialists are able to measure very effectively complex machined parts in a quick and reliable way via self-generating measure programs. Before serial production is started, the first piece of each series is checked on the CNC controlled 3D machines. In case of positive result, serial production gets started. Random checks are performed on the running production. Results from all relevant measurements get recorded by quality inspection workers. After evaluation of all results recorded, long term actions are suggested by our professionals.

This approach enables us to achieve continuous improvement in our production process.

Assembly inspection
VHVquality standards require that every single piece of valve passes a tightness test performed by assembly line operators and randomly checked by independent quality workers. Tightness tests at VHVare performed under standard conditions ace. PED 97/23/ES. VHV testing procedures also comply with API 598. EN 12266 and GOST R. Tightness tests according to other standards can be provided upon customer request.

Final inspection
At VHV. final quality inspection is performed after complete valves are handed over from the assembly line but before they are made available for expedition by the packaging and storage department. During the final inspection process, finished valves are inspected for conformity with customer requirements. This check is performed by auditors who are independent the production department, and only after conformity is confirmed, valves are released for expedition.

Adhering to these strict quality assurance and control standards has helped us to keep non-conformities to an absolute minimum.
