Gemü‘s 740 series, available in DN 8 to 100, has been specially designed for demanding applications in the pharmaceutical and foodstuff industry. The cavity filled seat consists of two special half shells made from TFM. This sealing material complies with the stringent requirements of the US Food and Drug Administration (FDA) and conforms to FDA 21 CFR 177.1550. The spindle is triple sealed by pretensioned spring washers, V-rings and a conical gasket. The sealing package can be readjusted and requires little maintenance. The series is compliant with the TA Luft (German Clean Air Act). At the same time, this design ensures low friction as well as a long service life of the sealing system in conjunction with the finely machined spindle.
When open, the ball valves offer a good flow capability. The maximum permissible operating temperature is 180 °C. In the case of steam, the maximum permissible steam pres-sure is 8 bar. The maximum permissible operating pressure is 63 bar for liquids in the nominal sizes DN 8 to 50 and 55 bar in the nominal sizes DN 65 to 100. Butt weld spigots to DIN 11850, DIN ISO 1127, ASME BPE as well as clamp connections in accordance with ASME BPE are available as standard connections. The Gemü 740 is a 3-piece ball valve with top flange. Besides the hand lever, pneumatic quarter turn actuators and motorized actuators can also be mounted.
