新型铸钢控制阀由KSB为工业

新型系列可采用铸钢(GP 240 GH)，从DN 15到DN 200，公称压力等级为PN 40。最高允许温度为450℃。无需任何特殊工具，只需拧开阀盖螺栓即可拆卸阀门。这使得用户能够更换整个阀门饰件，并使其与不同的控制要求相匹配。这种阀门内饰包括各种不同的阀座和阀塞直径，适用于所有公称直径。均可提供等百分比和线性特性阀塞。阀座的设计使它可以在两侧使用。如果座椅损坏，只需将其翻转而不是更换就足够了。该阀门还具有抛物线塞、穿孔塞和多孔保持架，以解决气蚀和噪音问题。阀门制造商KSB为严格的密封性要求提供软阀座阀塞变体。 Stem sealing on standard variants is ensured by a maintenance-free spring-loaded PTFE V-packing, and graphite gland packings are used for temperatures above 250 °C. Balanced plugs are available on request for valves larger than DN 50 (i.e. from DN 65) and allow the use of small, inexpensive actuators. The operator can choose between electric and pneumatic actuation. The electric actuators offer input and output signals from 0/2 to 10 V or 0/4 to 20 mA. In addition, 3-point (Open/Stop/Closed) actuation for straightforward control applications is also available. The actuators which are available in five sizes and as 24 V, 230 V and 400 V variants have maximum actuating forces of 25,000 Newton. The pneumatic diaphragm actuators which come in three sizes have a maximum actuating force of 55,000 Newton.
