Product Description
SUN PBDB-LQN / EFV-T11AG38 Hydraulic Pilot-operated Pressure Reducing Valve Manifold Assembly
The SUN PBDB-LQN / EFV-T11AG38 is a premium hydraulic pilot-operated pressure reducing valve manifold assembly designed for precise and stable fluid power control. At its core is the highly reliable Sun PBDB-LQN cartridge valve, seamlessly integrated into a durable rectangular manifold block. This assembly effectively reduces a high primary pressure at the inlet to a constant, lower secondary pressure at the outlet, regardless of fluctuations in the primary circuit. Engineered for demanding industrial and mobile applications, it offers a highly adjustable pressure reducing range of 5 to 25 bar and withstands a maximum inlet pressure of up to 240 bar, with a flow capacity of up to 40 L/min. The manifold features three standard G3/8 threaded working ports (marked 1, 3, and G) and is available in either robust black oxide steel or lightweight aluminum to suit specific system requirements. The cartridge valve includes a hex body with a threaded adjustment stem for easy tuning, and the unit ships with protective plastic caps to ensure port integrity.
