Cole-Parmer Y11-C444D (330 CGA) 高纯度气体调节器

Cole-Parmer Y11-C444D (330 CGA) 高纯度气体调节器

用于实验室研究使用的轻度腐蚀性气体

隔膜无衬垫阀提高了系统的纯度

无螺纹设计使用寿命更长

这些不锈钢单-双级高纯度的调节器用于非腐蚀性分析，轻度腐蚀性和流程应用需要精确，稳定的输送压力控制。隔膜无衬垫的1/4“压缩管接头允许出口阀的流量控制和维护系统的纯度。

单级稳压器具有卷曲的不锈钢膜片密封提供良好的调节特性，并允许内部真空清洗

双级式调节器配备了卷曲的Hastelloy C-22隔膜密封件，以防止污染消除软密封件的需要，泄漏率小于2×10 -8 ccs 氦。这两级型号产率低于0.04/100 psi 入口变化。

Designed for laboratory research using mildly corrosive gases

Diaphragm packless valve promotes system purity

Threadless seat design provides longer life

These stainless steel one- and two-stage high-purity regulators are designed for non-corrosive analytical, mildly corrossive and process applications requiring precise, stable delivery pressure control. A diaphragm packless outlet valve with a 1/4" compression tube fitting allows flow control and maintains system purity.

Single-stage regulators feature a convoluted stainless steel diaphragm seal that provides excellent regulating characteristics and allows for internal vacuum purging

Dual-stage regulators feature a a convoluted Hastelloy® C-22 diaphragm seal that prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10–8ccs helium. The two-stage models yield a delivery pressure change of less than 0.04/100 psi inlet change.
