Cross Keluos butterfly valve technical parameters nominal diameter: face-to-face standard: connecting flange: flange sealing surface: top flange: Valve identification: sealing grade: working temperature: working pressure: - ensure two-way complete sealing of the valve - fine machining of valve body and valve plate, small torque and long service life - three bearings on the valve stem prevent valve stem deflection, even after many years of use, It can still ensure high positioning accuracy - four flange positioning holes ensure the correct position of the valve during installation - can be installed in any direction - maintenance free - removable, materials can be recycled - spraying industry, Silicon free treatment valves - chemical and petrochemical - water treatment and sewage treatment - pneumatic transportation - shipbuilding - Energy Engineering - transportation of dangerous goods (EN 14432) DN 50 - DN 1200 (DN 50) can be selected   Only PN 10 / 16) en 558 series 20 ISO 5752 series 20 API 609 Table 1 en 1092 PN 6 / 10 / 16 ASME Class 150 as 4087 PN 16 en 1092 form a / b ASME RF, FF EN ISO 5211 en 19 en 12266 (leakage rate a) ISO 5208, category 3 - 40 ° C to + 200 ° C (related to pressure, medium and material) max. 16 bar

Torque Kv value-   Kv value (m) ³/ H) is the measured water flow when the water temperature is 5 ° C ~ 30 ° C (41 ° f ~ 86 ° f) and the pressure difference is ∆ P = 1 bar - the Kv value listed in the right table is measured by the authoritative European Hydraulic Laboratory - the maximum allowable medium flow rate: liquid: maximum 4,5 M / S; gas: maximum 70 m / S - when the opening is 30 ° ~ 70 °, the flow and opening are approximately linear - cavitation should be avoided. More data, Please contact our engineer - when the data listed in the right table is liquid or lubricating medium, the starting torque value of the valve - the data listed in the right table is the reference value, and the actual value is related to many factors, such as pressure, medium, rubber material, quality, temperature, etc. - for more data, please contact our engineer - granular powder (non lubricating) medium MD x 1, 3 - dry gas / high viscosity medium MD x 1,2
