HSTECH is proud to be the exclusive supplier of valve products for Combet Valves B.V, a Dutch company specializing in design, engineering and manufacturing of compact Check Valve, Ball Valve & Sub-sea Valve.

1. Production Range

Valve design has not changed very much over the years, especially if we delve into the history of the ball valve. There are two types of ball valve designs that primarily dominate this market, namely the floating and the trunnion design. Although manufacturers have produced these basic valve designs for many years, the designs have changed very little. One aspect that has changed is the compactization of the floating design.

The space savings alone is nearly 50% of conventional flanged end ball valves. We concentrate on the basics, saving Weight, Space and Money. By taking this “no-nonsense” approach and sticking to our core business, we are able to provide our customers with efficient, practical designs that work in the field.

3. Size range

Our range of 1” -6” NPS, high pressure valves are the smallest in the market, saving you space and weight, when compared to standard API 6D and API 6A valves.

4. Application

– Upstream oil & gas manifolds for land based and onshore installations
