Why Valveworks USA?

As complex and multi-faceted as this question is, the most important answer is that Valveworks USA delivers.   The proven relationship between Valveworks USA and its customers is that Valveworks delivers the product which the customer requires for the service requirement, when the customer requires it, with quality that performs and is reliable at a globally competitive value.

Someone may ask, how is this achieved superior to other suppliers in the industry? The answer is in the many years of building an infrastructure directed to achieving customers demand for performance and reliable quality product through responsive precision engineering, diligent quality management, and Valveworks USA’s inhouse manufacturing.  No customer’s demand or request for a valuable quality product or service has ever gone unattended regardless of concern.

The lowest cost product is one which outperforms expectations and saves time and cost in the long run. The Valveworks way to create this quality product is to put the engineering and quality into each and every component it manufactures.  Valveworks USA is one of the very few manufacturers which designs, engineers, and manufactures every component which goes into its API 6A gate valves and wellhead equipment used in oil and gas drilling, completions and production. The concept is that if you manufacture a superior quality component, along with quality managed validation and testing, you will create a superior product.

Material Selection

Material selection and availability begins with global procurement and quality management. Global infrastructure affords Valveworks a global competitive edge inaddition to providing availability of material. Valveworks USA acquires all possible availability of steel from the USA while accessing material from our three production plants in India.
