Gate Valves
The resilient seat gate valves provide the most reliable solution for networks. They guarantee perfect watertightness, without leakages and smooth flow with minimum losses. They are designed so as to avoid corrosion risks. No bolts and nuts are found externally.
The construction materials are of high quality and endurance that assure long life valve operation. The valve can be dismantled without being removed from the pipeline. The valves are internally and externally coated by epoxy powder, electrostatically applied, thickness 200μm (extra thickness upon request).
The operation of the valve is achieved by a handwheel and with suitable spindle extensions in case of underground installation or deep manholes. The valve can be accompanied by a gearbox which is mounted on a special adjustment head.
The gate valves are manufactured according to the international standards ISO, DIN, EN. They are tested thoroughly at each stage of production. The tests are executed according to DIN 50049 3.1B / EN 10204-2004 in the test laboratories of latest technology
