Dwyer 38R系列自力式温控阀

38R系列自动温控阀不需要外部电源,适用于调节储罐、流程流和各种工业设备的温度。
执行机构是由一个坚固的压铸铝外壳与全封闭波纹管组件和内部超程保护。
阀门提供1/2"至6"连接尺寸和1/8"至6"端口尺寸。
阀体可采用单阀座直接或反向作用,双阀座直接或反向作用,3路设计,阀体材料有四种选择:青铜、铸铁、铸钢和316不锈钢。
执行机构可用指示或不指示刻度盘或故障安全.非指示执行器具有较低的轮廓,在空间限制可能是一个问题时,应该实现,而指示执行器允许操作者验证过程温度并帮助温度调整。
故障安全执行机构的设计是为了使阀门在终端系统发生意外损坏时在安全控制位置失效(在冷却应用中打开,在加热应用中关闭),从而导致压力电荷损失。
38R系列也提供了各种各样的毛细血管、灯泡和套管。
