38R系列自動溫度控制閥不需要外部電源，適用于調節儲罐、工藝流程和各種工業設備的溫度。 執行機構采用堅固的壓鑄鋁外殼，具有全封閉的波紋管總成和內部超量程保護。 閥門有1/2"到6"的連接通徑和1/8"到6"的端口通徑。 這種閥體有單閥座直接作用或反向作用、雙閥座直接作用或反向作用三種結構形式，閥體材料有四種選擇:青銅、鑄鐵、鑄鋼和316不銹鋼。 執行機構有或沒有指示刻度盤，也有故障保險裝置。 非指示執行機構具有較低的輪廓，當指示執行機構允許操作員驗證工藝溫度并幫助溫度調整時，應在可能存在空間限制的地方實施。 故障安全執行機構的設計目的是，如果終端系統發生意外損壞，導致壓力負荷損失，則會導致閥門在安全控制位置(冷卻時開啟，加熱時關閉)出現故障。 38R系列還可提供各種毛細血管、和溫度計套管。
