TECHNICAL ADVANTAGES FOR ENAMELED VERSION, THE VALVE INTEGRATES AN EDGE PROTECTION (1) PLACED ALL AROUND BETWEEN THE BODY AND THE BONNET. 6 The technical data and performance may be modified without prior notice depending on the technical advances.

07: Male guiding system with locking tab bayonet system, The INFINITY gate valve has no threads, enabling a continuous coating and therefore avoiding corrosion problems. Moreover, it is easy to remove the stuffing nut, with the valve under pressure and fully open, in order to change the O-ring. * List of the countries on request. TECHNICAL ADVANTAGES 04: Stem and collar made in one piece in stainless steel for better resistance to axial load and to withstand higher operating torques. A polyamid washer (1) placed under the collar allows to reduce friction torque and protect coating inside the...

OPTIMUM PROTECTION The INFINITY resilient seated gate valve has been designed with even more rounded surfaces and more ergonomic shapes that allow more uniform coating and ensure protection of the highest quality. Minimum 250 micron corrosion protection The new state-of-the-art coating line installed in BELGICAST, based on an innovative process with fluidized bath and dipping robot, ensures an excellent adhesion, as well as controlled thicknesses and perfect continuity of the coating without porosity. The epoxy powder used by BELGICAST is approved for use with potable water by the most prestigious...

QUALITY & TESTING VALVE TESTING ACCORDING TO EN 12266-1 - EN 1074 Testing pressures • Shell tightness: 25 bar at room temperature. • Seat tightness: 17.6 bar at room temperature. Minimum test duration (in seconds) Nominal diameter DN Up to DN50 included From DN65 up to DN150 included From DN200 up to DN300 included DN350 and above Maximum allowable seat leakage The criterion for seat leakage of BELGICAST resilient seated gate valves is Rate A: no visually detectable leakage for the duration of the test (“zero drops”). Quality control • 100% of BELGICAST resilient seated gate valves are tested...
