Globe Valve, Metal. Sectional drawing

Transcription

1 Globe Valve, Metal Construction The GEMÜ pneumatically operated 2/2-way globe valve has a low maintenance membrane actuator which can be controlled by inert gaseous media. The valve plug is fixed to the spindle in such a way as to allow flexing during closure in order to ensure tight shut off. The valve spindle is sealed by a self-adjusting gland packing providing low maintenance and reliable valve spindle sealing even after a long service life. The wiper ring fitted in front of the gland packing protects it against contamination and damage. Advantages Good flow capability Broad range of operating temperatures and s Accessories: Stroke limiter / optical position indicator / manual override / pilot valve with manual override / electrical position indicators / electro-pneumatic positioner Sectional drawing

2 Technical data Working medium Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and seal material. Max. perm. of working medium see table Media temperature -1 C to 18 C Max. permissible viscosity 6 mm²/s (cst) Other versions for lower/higher temperatures and higher viscosities on request. Control medium Inert gases Max. perm. temperature of control medium 6 C Max. control 7 bar Filling volume Actuator size 3, 5, dm³ Actuator size 4, 6, dm³ Ambient conditions Max. ambient temperature 6 C Maximum permissible seat leakage rate Seat seal Standard Test procedure Leakage rate Test medium PTFE DIN EN P12 A air Metal DIN EN P12 F air Operating Control function 1 Control function 2 Control function 3 Control Actuator size Weight Operating Control Actuator size Weight Operating Control Actuator size Weight Kv values DN [bar] [kg] [bar] [kg] [bar] [kg] [m³/h] / / max max / / max max / / / / max max / / / / max max / / / max max / / max max / max max / / max max / max max / max max / max max max max All s are given as gauge s, when applied upstream only. Higher s and temperatures on request. Kv values determined acc. to DIN EN 6534, valve body material cast iron EN-GJL-25 and flanges EN 192. The Kv value data refers to control function 1 (NC) and the largest actuator for each nominal size. The Kv values for other product configurations (e.g. other connections or body materials) may differ. 2
