Discover RAVETTI also known as the Italian market leader in the development of new tools for the maintenance of pressurized pipes, gas bags and hot tapping machines. The first Italian manufacturer on the world market. Ravetti has succeeded in developing solutions that bring the hot-tapping and flow-stopping tools to higher levels of safety and functionality.
STOP/SYSTEM
The innovation of STOP/SYSTEM is based on the original mechanical expansion of the rubber gasket that makes it possible to always achieve a perfect seal through the stopper, regardless of the back pressure of the liquid. Fully compatible with steel, ductile cast iron and polyethylene pipes. The modularity and interchangeability of the components with different piping materials allow a significant reduction in the investments in capital, consumables and operator training. STOP/SYSTEM operates up to a pressure of 8 bar, pipes from 2" to 10".
MINISTOP
Ministop, the safest, most compact and reliable system for temporarily sealing pipes from 1/2" - 2". Ministop works up to a maximum operational pipe pressure of 12 Bar and is applicable to gas, water, system, heat and other pipes. Complies with VIAG-14
RAVETTI FLOWSTOP
Flowstop is the only temporary shut-off system that closes 100% leak-free under all circumstances. The reliability of the single solid sealing mechanism is at an unprecedented high level, so much so that single block sealing is permitted on 24" 40 Bar gas transport pipelines! (Ref. Ital/Gazprom) Ravetti Flowstop has 3 standard systems: Flowstop for steel, cast iron, AC, PVC, up to 24", 12 or 25 Bar. Flowstop for PE, up to DN350, 8 Bar. Flow stop for all cladding materials (Hybrid system), up to 12", 12 Bar.
