DWYER SERIES 38R SELF-ACTING TEMPERATURE CONTROL VALVE  | POWER-FREE REGULATOR

The Series 38R uses a vapor-filled thermal system to actuate a valve bellows directly as temperature changes. This “set-and-forget” device is recommended for stable systems where small valve stroke modulations can correct temperature drift. It features a rugged die-cast aluminum housing and is available in multiple body materials including bronze, cast iron, and 316 stainless steel.
