Pump-protection valves from Red Valve Co. can be used throughout a plant to isolate pumps and equipment and control fluid pressure and flow as it is processed. They are designed for various pressures, temperatures and chemicals for any equipment application and to manage the corrosive and abrasive nature of numerous fluids. Gate valves section off the pump when service is required. Tideflex check valves ensure that fluid in the system flows in one direction to prevent pump backflow contamination. Automatic recirculation valves protect pumps during low-load operation and startup. 412/279-0044; www.redvalve.com.
