HPV HGV Flap Gates

The perfect introduction to Your process

For your requirements, you also can take advantage of HAZEMAG’s 75+ years experience in supplying hundreds of gate valves worldwide. Each application is carefully considered on its merits to decide which type and design of valve would be most suitable.

The purpose of these valves is to transfer flowing material from one process stage to another. Depending on the particular requirement, they can be used as feed or discharge valves, or as air locks to seal off a part of the process.

HAZEMAG gate valves are characterized by high reliability, extreme robustness and easy maintenance. Moreover, we place great emphasis on quality, a feature of our gate valves highly valued by all our customers.
