The F3-DGMPC-7-ABK-BAK-30 valve is part of the Vickers SystemStak Modular Valves series and is intended to block and release hydraulic flow in automated circuits. It is a pilot-operated check design, so reverse flow remains blocked until a pilot signal opens the poppet, allowing actuators to hold position under load. Pressure-operated actuation lets the unit respond directly to line pressure without external mechanical input, supporting compact stack layouts. A single-stage internal arrangement keeps the flow path simple for fast response. Subplate or manifold mounting positions the valve directly between other stack elements, and the ISO 4401-07 port pattern aligns with common industrial bases for quick interchange. The cast-iron body provides strength against repetitive loading, while Buna-N seals contain the working fluid and reduce leakage. Compatibility with anti-wear hydraulic oil means the valve can run in standard industrial power units without special fluids.
In operation, each check element opens after reaching a cracking pressure of 1.0 bar, which minimizes energy loss while still preventing unintended backflow. The assembly withstands a maximum operating pressure of 315 bar, enabling use in high-pressure mobile or stationary systems, and it passes up to 180 L/min to match medium-size pump outputs. Physical dimensions influence stack planning; the valve measures 8.3 in in length, 3.15 in in width, and 3.54 in in height, so technicians can predict manifold spacing. A weight of 16.5 lb aids stability during service yet remains manageable for single-person handling.
