Larox Flowsys has developed a pinch valve with fireproof structure, suitable for firewater and sprinkler systems in various industries and applications. Salty offshore and other seawater applications are very difficult to most metal valves, because saline water corrodes valves and makes them almost impossible to operate. Larox valves are most suitable for these applications as the non-corroding sleeve is the only part, which is in direct contact with the medium. The elastic sleeve also ensures that the valve does not jam or clog even if it has been closed for a long period. The new fireproof valve consists of AISI 316 body, SBRT sleeve, bronze bushings and an extra flange cover. It offers both the good fire resistance and non-corrosive, anti-jamming reliable operation certified by Det Norske Veritas type approval of fire water system valves.
