CHECK VALVE

Check valves, essential for preventing backflow, function as one-way valves allowing flow in one direction while closing to protect pipelines, valves, and pumps if the flow reverses. They find diverse applications, commonly positioned downstream of pumps to safeguard against reverse flow and potential water hammer damage. To ensure optimal system protection, the suitability of each check valve must be individually evaluated, considering factors like water hammer risk, acceptable pressure loss, and financial implications of selecting a valve with excessive safety margins. Check valves are integral in the oil and gas industry, with designs tailored for challenging and hazardous service conditions, offering precise control over fluid flow in various configurations. Emcor Engineering is a leading provider in this field.
