Sales and replacement services of dampers in large water tanks. We produce dampers with diameters from DN50 to DN150. Please remember that elements of this type should only be installed by specialist service teams.
Butterfly valves
Throttles are a component of most liquid media storage installations. Thanks to progress in the production of materials, especially elastomeric seals, it is possible to find the most effective solution for the designed installation.
The pass-through valves we offer guarantee complete external and internal tightness as well as uniform pressure distribution on the disc and tightness of the closure regardless of the direction of water flow.
