I. Valves
a. Overview
Since very beginning, Viet Engineering have promoted and distributed valves for Oil & Gas and other industries. Our features are reliable brands and quality, fast-track delivery time for projects and custom-made specifications. Our supplying products can serve for severe environment where high corrosion, pressure, temperature occur.
Viet Engineering offers a wide range of valves including: ball valve, gate valve, Globe Valve, Check valve, and Butterfly Valve on standard design. Besides, we are able to perform custom-designed specifications on request.
Together with supplying with products, services are also essential. We supply warranty service (standard or extended), maintenance, and repair for valves. The valve origin are: EU/G7, Korea depending on customer’s requirements.
We offer a standard document set with valves:
- Certificate of origin (by chamber of commerce or manufacturer)
- Certificate of quality and quantity (EN 10204 type 3.1 certificate). Third party inspection certificate/stamp is available on request.
- Drawings, manuals
