ARI-CHECKO-D Disc Check Valve DN40 55.001/PN40

Safe Flow Control at High Pressure with the Assurance of ORFA Industrial

As a critical component for flow control in industrial plants, the disc check valve ensures that liquid or gas flows only in the desired direction. Manufactured with ARI-Armaturen quality, this disc check valve is designed for high-pressure systems with nominal diameter DN40 and pressure class PN40. Thanks to its stainless steel body, the disc check valve exhibits superior resistance to corrosion and is used in many sectors, especially petrochemical and energy plants. With its compact wafer design, this disc check valve offers easy installation and instantly blocks reverse flow, protecting system components. With leakage rate Class A according to DIN EN12266-1, the disc check valve guarantees tightness and operates reliably at high temperatures up to 300°C. With a spring set pressure of 0.02 bar, the disc check valve responds sensitively even at small pressure differences. This disc check valve, available from ORFA Industrial stocks, ensures a long service life with an AISI 316 stainless steel body and AISI 316Ti internal parts. Using a disc check valve in your installation protects pumps and valves from damage due to backflow. Each disc check valve unit is shipped after passing strict quality controls.
