DGMDC3YPK41

The DGMDC3YPK41 valve belongs to the SystemStak Modular Valves series and is manufactured by Vickers. It is a direct check valve used to prevent reverse flow in hydraulic automation circuits. Pressure-operated actuation opens the poppet only when upstream pressure rises, removing the need for external control lines. The flow path is oriented toward the actuator so oil reaches cylinders or motors without restriction during forward motion. A cracking pressure of 1.00 bar (15 psi) sets the threshold at which the valve begins to open, giving smooth transition from static to dynamic flow. The unit tolerates a maximum operating pressure of 315 bar (4500 psi), making it suitable for high-pressure industrial manifolds. It handles up to 60 L/min (16.0 US gpm), supporting medium flow rates common in presses and machine tools. Petroleum oils are specified for compatibility, protecting internal parts from swelling or degradation. Subplate or manifold mounting simplifies stacking with other SystemStak elements and removes external piping.

The DGMDC3YPK41 connects through an ISO 4401-03 interface, which provides a standardized port pattern for multi-station blocks. The check element is positioned in Line P so system pressure is retained on the pump side while reverse flow is blocked. Viton seals withstand heat and petroleum oils, ensuring leak-tight service over long duty cycles. A required fluid cleanliness of 19/17/14 per ISO 4406 limits particle wear on the seating surfaces. Physical dimensions of 87.884 mm length, 47.498 mm width, and 39.878 mm height allow dense stacking inside restricted control blocks. These compact proportions help engineers combine several functions without expanding manifold size. Together, the interface, sealing, cleanliness, and size characteristics support reliable, space-efficient pressure control for hydraulic actuators.
