Valve Testing (EN 12266-1 - EN 1074 standards) Testing pressures Shell tightness: 1,5 times the allowable pressure at room temperature. Seat tightness: 1,1 times the allowable pressure at room temperature. Minimum test duration (in seconds) Nominal Diameter DN Up to DN50 included From DN65 up to DN200 (both included) From DN250 up to DN450 (both included) DN500 and above Maximum allowable seat leakage The criteria for seat leakage of Belgicast soft sealing gate valves is Rate A: no visually detectable leakage for the duration of the test (“zero drops”). Pressures and temperatures • Up to 25 kg/cm2...

Valve Testing (EN 12266-1 - EN 1074 standards) Operating Torque The operating torque of Belgicast soft sealing gate valves complies with the Maximum Operating Torque (MOT) requirement of the standard EN 1074. The chart shows the typical operating torque values of BELGICAST soft sealing gate valves with clean water and at room temperature. These values are only for orientation and can vary depending on the typical manufacturing variables. For other fluids and temperature please feel free to contact us. Please apply 1,3 as safety factor for actuator selection. DN 40 50 65 80 100 125 150 200 250...
