38R系列自动温度控制阀不需要外部电源，适用于调节储罐、工艺流程和各种工业设备的温度。 执行机构采用坚固的压铸铝外壳，具有全封闭的波纹管总成和内部超量程保护。 阀门有1/2"到6"的连接通径和1/8"到6"的端口通径。 这种阀体有单阀座直接作用或反向作用、双阀座直接作用或反向作用三种结构形式，阀体材料有四种选择:青铜、铸铁、铸钢和316不锈钢。 执行机构有或没有指示刻度盘，也有故障保险装置。 非指示执行机构具有较低的轮廓，当指示执行机构允许操作员验证工艺温度并帮助温度调整时，应在可能存在空间限制的地方实施。 故障安全执行机构的设计目的是，如果终端系统发生意外损坏，导致压力负荷损失，则会导致阀门在安全控制位置(冷却时开启，加热时关闭)出现故障。 38R系列还可提供各种毛细血管、和温度计套管。
