型号描述

基于 Bürkert 公司针对模块化过程阀和传感技术的理念，2301 型直座阀的设计满足所有的实际应用要求，即使在恶劣的使用条件下。通过经验证的、能够自动调整的压盖，可以实现最长的使用寿命和的密封性。每个直座阀体均可装配三到五个不同的阀座尺寸。这种抛物线状阀座，能够根据通过量的变化得出一个准确、可重复的特征曲线。接口密封用阀锥可提供不锈钢型或配有耐久 PTFE 密封件的类型。驱动装置的设计可简便整合所有结构分级中的自动化单元，以及数字的电气位置调节器乃至过程调节器。高度集成的系统由阀门和自动化单元构成，其特征在于设计的紧凑性和表面光滑性、集成式的控制空气管道、防护级 IP65/67/NEMA4X 以及高化学抗性。

1）出色的调节质量，带有紧凑型外壳
2）通过可更换的阀座实现了较高的使用寿命和多变性
3）自动化单元及 ELEMENT 的简单集成
4）带有法兰接头、连接套头或焊接接头的不锈钢外壳
5）适合 10 bar(g) 蒸汽

Type Description

In line with Bürkert’s philosophy the construction of the type 2301 globe valve fulfils tough criteria for process environments. Unrivalled cycle life and sealing integrity is guaranteed by the proven self adjusting spindle packing with exchangeable V-seals. Each globe valve body can be fitted with up to five sizes of trim sets. These parabolic trims provide a reliable and repeatable characteristic to vary the flow. The control cones are available in either stainless steel or with a durable PTFE seal or PEEK seal for tight shut-off. Leakage class III, IV or VI are available. The design enables the easy integration of automation modules whether they are digital electropneumatic positioner or process controller. The fully integrated system has a compact and smooth design, integrated pneumatic lines, IP65/67 protection class and superior chemical resistance.

1）Excellent control characteristics
2）High cycle life and maintenance-free operation
3）Flow optimised body in stainless steel
4）Several Kvs value per port size due to removable trim kit
5）Control units can be mounted directly without external tubing
