The DAIKIN MR-03P-3-40-56 is a highly reliable modular hydraulic relief valve engineered for precise pressure control within industrial hydraulic systems. Manufactured by Daikin Industries, Ltd., this valve acts as a crucial safety and regulation component, effectively managing pressure in the P-line and venting excess fluid to the T-line through its normally-closed relief circuit. The unit features a heavy-duty cast valve body integrated with a rectangular mounting block and four bolt holes for secure subplate installation. Operators can easily configure system pressure using the integrated hex pressure adjustment screw, which is secured by a heavy-duty lock nut to prevent drift during operation. Built to Daikin’s exacting standards, this valve ensures optimal performance and protection against overpressurization in demanding fluid power applications.
