Changeover Valves for Industrial Refrigeration, Cryogenic & Liquefied Gas, and Hydrogen Applications


For Refrigeration applications:

Changeover valves play a crucial role in the smooth operation and safety of industrial refrigeration and hydrogen systems. These unsung heroes of process control quietly manage the flow of fluids, enabling seamless switching between sources, equipment isolation for maintenance, and even system redundancy for critical safety applications.

In the fast-paced world of industrial refrigeration, downtime is a costly enemy. A leaky evaporator or malfunctioning compressor can bring production to a screeching halt, leading to lost revenue and spoilage. Changeover valves step in as silent guardians, allowing technicians to isolate the affected component while the remaining system continues to operate uninterrupted. This quick and efficient isolation minimizes downtime and keeps your cool room, well, cool.
