Introduction

Controlling water temperature is critical for photographic processing. We make two series of valves that hold water temperature to +/- 0.2 degrees Fahrenheit, the D Series and the K Series. These valves are called water temperature control valves, mixing valves, tempering valves, thermostatic valves, etc. No matter what you call them, they are an important tool to aid in fine photographic processing. See our article A Biased Guide to Water Temperature Control in Photographic Darkrooms for more information. See below for a comparison between the D Series and the K Series.
