This picture shows the KAMAT High-Pressure Unloader Valve DN50

Smooth control of flow directions and pressure with the unloader valves of KAMAT

KAMAT unloader valves are the ideal solution when it comes to precise pressure control in fixed or varying volumes. A fast and smooth acting high-pressure valve that redirects the flow of the conveyed medium when the desired pressure on the discharge side is reached.

The ideal companion for pressure testing units of pipelines and vessels or other volumes

The smooth action makes it a trusty partner when hydrostatic testing pipelines and vessels in all conditions. Further increased reliability is archived by the addition of a surge valve which is further protected by its own filter. This added filter is of great importance when solid particles are included in the conveyed medium, examples for that being the reinjection of drill slurry into the drilling hole. But our valves are not only reliable but also easy and versatile in their control. They can be controlled mechanically, pneumatically, electrically or hydraulically, all with the option for it to be remote controlled. Manufacturing using special materials is also possible to provide an ideal solution for the process industry.
